Towards an Ecosystem of Hospitality: The Dynamic Future of Destinations

: Digitalization, new work and leisure concepts and global challenges are transforming the way we live. More stakeholders, including residents and entrepreneurs, actively participate in the implementation of alternative socio-economic concepts; as such, entrepreneurial ecosystems are seen as drivers of regional development. The research still lacks holistic approaches to the application of ecosystems in tourism destinations. Hence, the objectives of this article are to capture research on entrepreneurial ecosystems in tourism and, speciﬁcally, to derive a holistic model that integrates destination and location management across stakeholders. This research utilizes the method of a systematic literature review, starting with 597 articles on ecosystems. Following four stages of exploring the literature, the results show that most articles have been published in rather isolated ﬁelds of smart tourism or quality of life aspects. Based on the rather qualitative review that reveals speciﬁc ecosystem components, we propose a model of an “Ecosystem of Hospitality” (EoH). Focusing on stakeholder interaction and encounters, the EoH fosters the adoption of the entrepreneurial ecosystem to destinations in a dynamic approach. The practical implications are, for example, a broader consideration of various stakeholders, including the local population, and a switch in typical destination management tasks from mere tourism service production to regional development and living space management.


Introduction
Locations and destinations are in a state of transformation. The framework conditions of living and economic spaces are changing as a result of technological innovations and digitalization, new work concepts or dynamic developments in cities [1][2][3]. Destinations, in particular, are undergoing a fundamental transformation, with sustainability and resilience becoming central elements of a new understanding of travel [4,5], which results in a new role of tourism in the society and economy. More than ever, cities, municipalities and regions have the opportunity to put people at the heart of the discussions on spatial development and to involve a variety of stakeholders. Local actors take on creative responsibility and revitalize the cultural and creative scene [6]. A culture of personal encounters lays the foundation for sustainable location, destination and living space development and establishes a new relationship between hosts and guests.
From a conceptual perspective, the importance of tourism and leisure as soft location factors has often been taken into account [7,8] and is also shown by models of integrated location development [9][10][11], which define companies, workers, tourists and residents as core stakeholder groups. From a mix of entrepreneurs, young creatives, tradition-conscious residents, cultural workers and (international) guests, new concepts are emerging that break up previous structures and bring a transformation. The focus is no longer on the quality of experiences alone, but on the quality of life as well.
These new concepts shape the integration of entrepreneurs and the development of a lively start-up scene in the context of entrepreneurial ecosystems (henceforth referred to as ecosystems) [8,10,[12][13][14]. With their innovative and creative charisma, these entrepreneurs are now also drivers of district design and contribute to the attractiveness of a location. The first adaptations to tourism [8,10,15] also show interfaces with the destination, e.g., in leisure-relevant services for the local population and tourists on the one hand, and for start-ups seeking a dynamic environment on the other.
However, the research lacks conceptualizations that display how an ecosystem in tourism destinations may look like, including business functions, output orientation, processes and encounters [16,17]. Similarly, the role of networks in the context of touristic, cultural and local development [18] as well as the interactions of guests with other stakeholders [19] need to be further elaborated. Lastly, there is a need to adopt the entrepreneurial ecosystem approach to creative tourism and culture-based contexts [18]. By investigating these research gaps, our research aims to re-conceptualize destination development and encourage a transformation of the tourism industry. To do so, the objective of this article is to adopt the ecosystem potentials at the destination level by answering the following research question: What are the potentials of the entrepreneurial ecosystem approach in destination development, and how can a holistic Ecosystem of Hospitality be conceptualized?
In contrast to strategic networks, our contribution aims to systemize current research on entrepreneurial ecosystems in the spatial setting of destinations to derive a model of an "Ecosystem of Hospitality" (EoH). In short, the EoH integrates the theoretical approaches of location, destination and living space management (Section 2; theoretical background). The systematic literature review (Section 3; methodology) unfolds the potential to increase the connectivity of multiple stakeholders (Section 4; results of the literature analysis). The derived model of the EoH (Section 5; discussion) recognizes the interrelatedness of local stakeholders across sectors and emphasizes the relationship and interactions between locals and guests. These are referred to as "hospitality", exceeding the traditional definition of hospitality in terms of fare or accommodation provision (cf. Section 5). The present article proposes an integrated destination, location and living space development and, thus, (1) contributes to discussions of alternative approaches in tourism destinations, following contemporary changes and challenges, and (2) opens new potential research paths (Section 6; conclusion).

Current Challenges of Destination Management
A destination is a "geographical space [ . . . ] which a visitor (or visitor segment) chooses as their travel location. It contains all facilities essential for accommodation, gastronomy, entertainment/activity during the stay. Hence, it is that competition unit within incoming tourism that needs to be managed as a strategic business unit" (translated from German) [20] (p. 54). According to Wiesner [21], destination include aspects such as culture, sports, nature, cuisine, accommodation, health, local traditions, shopping, leisure, sightseeing or a transport and communication infrastructure. This understanding of destination management, therefore, requires an interplay of multiple stakeholders and a consideration of their various interests and demands.
The current challenges of destination management are manifold. Among them are global challenges such as societal change, demographic change or the digital transformation [22,23]. Recent discussions on resilient approaches aim to address these and provide solution attempts, in tourism and beyond [24]. The growing inequalities and income gaps between nationalities, genders or economic sectors are general issues and challenges that are not exclusive to tourism, but are particularly present in the industry due to the economic scope. Hence, alternative concepts are needed that focus on public welfare considerations [25]. A more tourism-specific issue in the context of experience creation is the development of authenticity and story-telling, which has become essential in tourism to individualize tourist offers [26]. This is, to some extent, connected to the emerging relationships between guests and locals, which can be built around pragmatic (i.e., economic), experiential (i.e., experience) or spiritual (i.e., hospitality) values [27]. Further challenges such as overtourism or the recent COVID-19 pandemic have shown that a relationship exists between tourism and the quality of life of residents within a city or region. The emergent discussions on overtourism and similar issues of mass tourism stimulate the need for an integrated, holistic development of the living space that allows for the participation and involvement of various stakeholder groups within the different processes and layers of destination and location management to meet the needs of individuals as well as society at large [28]. In doing so, experiences will be created for visitors and residents alike, local interest groups will be included in decision-making processes, and residents may benefit from the visitor economy and improved urban infrastructures [29].
It has been pointed out that destinations that aim to be competitive in a future global market not only need a strong brand, functioning infrastructure and professional distribution, but also committed entrepreneurs and a well-conceived innovation and product development [30]. Therefore, there is a need for a more holistic perspective of destination management that considers all actors and stakeholders.

The Role of Urban and Rural Development for Tourism
Regional development focuses on the improvement in socio-economic and ecological conditions within all types of regions, from urban to rural areas [31,32]. Hence, a distinction can be made between urban and rural development, whereby the overarching aim is to develop and improve living conditions in urban or rural areas.
In Europe and America, the relationship as well as the interaction between urban and rural areas has changed significantly, with industrialization and increasing economic growth. In the past, village regions were seen as a food and material storehouse for urban areas. In the age of globalization and the rise of the knowledge economy, rural areas in industrialized countries have developed into modern, diverse and creative places to live and spend leisure time [33]. Similar to urban areas, rural areas are always confronted with changing conditions, and megatrends such as global economic power (1), demographic and social shifts (2), accelerating urbanization (3), the rise of technology (4) and climate change and resource scarcity (5) have an impact on urban and rural development. Megatrends not only drive the transformation of the world, but can also be seen as one of the greatest challenges and opportunities for society [34]. In addition, there are discussions about multi-locality. Today's society divides its everyday life into several locations, and living and working places are not always close to each other. Although this can prevent daily commuting or migration, demands and expectations for space (e.g., infrastructural connections, housing market) change and financial or psychological strains can arise for society. Nevertheless, multi-locality promotes participation in social and economic contexts and networks as well as the possibility of financial transfers [35].
Another consequence of multi-locality and increasing urbanization is urban fragmentation. Urban spaces, and thus urban life, have expanded further, and the boundaries between urban and rural areas have become blurred [36]. "Rural-urban linkages play a crucial role in the generation of income, employment and wealth" [37] (p. 20). However, the implications of this change for urban and rural development are, as of yet, unknown, and further research is needed. At the present time, the COVID-19 pandemic is the main concern in urban and rural development. New fields of action are arising and sustainable transformations in cities and villages can be driven forward. The COVID-19 pandemic offers the opportunity, for example, to question spatial use concepts, strengthen the resilience of urban and rural areas or criticize housing policy. In the context of the crisis, sustainable, resilient and health-oriented urban and rural development can be promoted, which should consider the changes in society, innovations in science and the economy, political changes as well as digitization. Nevertheless, the approach to a post-crisis period is still unclear [38].
Still, approaches can be found in science that propose practical ways forward. For example, Knieling's [39] research shows that urban and rural planners are the pioneers of sustainable transformation. Similarly, the concept of the smart city, in which innovative technologies are used to further develop the city's infrastructure and services, offers potential. However, the understanding of the smart city varies. It is understood as a future market, as a field of technological innovation or as a solution to existing energy and resource problems [40]. Thus, there is no universally valid definition of the smart city to date. According to Shcherbina and Gorbenkova [41], however, the following central elements of a smart city can be named: E-governance and citizen services (1), waste management (2), water management (3), energy management (4), urban mobility (5) and others, such as tele-medicine and education. With regard to tourism, the smart city represents a development platform that enables the establishment of a smart tourism destination. Here, the focus is on the intelligent use of information and communication technology by tourism stakeholders [42]. Finally, there is a mutual interaction between urban and rural development, and both areas can influence each other negatively as well as positively [43].

Concepts of Location Development
Wiesner [21] (p. 23) defines a business location a "a geographically or functionally defined area, where activities of the value creation process are taking place and being supported". These activities encompass procurement, production, trade, services, education and science, as well as governmental institutions and programs, and result in outputs that are of interest for both internal and external players. Within locations, clearly defined economic districts aim to attract investors, businesses and workers. Two dominating district types are industrial districts and clusters. According to Becattini [44], an industrial district is "a socio-territorial entity which is characterised by the active presence of both a community of people and a population of firms in one naturally and historically bounded area. In the district [ . . . ] community and firms tend to merge" [44] (p. 13). Similarly, a cluster is a "geographically proximate group of interconnected companies and associated institutions in a particular field [that] encompass an array of linked industries and other entities important to competition" [45] (p. 16).
Therefore, the functions and attributes of locations are manifold and can be economic, trade, technological, educational, leisure, health or of another nature. Locations that are perceived as attractive for investors or businesses often combine various attributes. The perceived quality of a location can also be derived from the quality of its hard and soft location factors, some of which are infrastructure (logistics, public transport or communication), political stability, social climate, quality of the workforce, the attraction of the domestic market, funding opportunities, labor costs, taxes, etc. [21].
As a more recent development, the entrepreneurial ecosystem approach, with its innovative character, can be seen as a driver of regional, local or sub-local-that is, neighborlydevelopment and boost a location's attractiveness. In such an ecosystem, there is a strong interdependence between different agents and factors, with entrepreneurial activity being the core output [46]. A similar concept is that of the entrepreneurial destination, allowing residents to use and enjoy facilities initially built for tourists, and startups and businesses to profit from a vibrant, dynamic social environment [10].

Integrative Approaches
One of the earliest attempts to establish an integrated location and destination management approach was made by Bieger et al. [20]. They replaced these terms with the concept of regional management, which combines societal, natural, technological and economic aspects, as well as resources, and the values and interests of various stakeholder groups, with tourists, residents and businesses being the most important ones. According to their model, an integrated approach consists of three management layers: normative manage- ment, which focuses on achieving viability and the development of a region; strategic management, which recognizes and utilizes potential in order to achieve success; and operative management, which focuses on success and profitability.
Pechlaner et al. [47] speak of different levels of integrated location and destination management, such as destination governance-that is, an integrated offer and coordination of actions-or regional governance, which refers to an inter-sectoral coordination of actions and a focus on regional competitiveness.
Another approach is that of place management, through which different factors, such as natural resources, regional or national framework conditions, transport and communication infrastructure, human capital, quality of life or economic infrastructure-the latter encompassing both tourism-and economy-related facilities-are combined with a complex management task [21]. This allows for place managers to cooperate with and involve numerous stakeholders, such as politician and political initiatives, governmental institutions, universities and educational providers, scientific and research institutions, businesses, economic associations, location and economic development agencies, tourism organizations, societal associations, media, religious institutions, accommodation providers, gastronomy, sport and leisure facilities, health institutions, cultural facilities or residents.
Integrated approaches such as these are increasingly gaining academic, political and economic attention, as the variety of soft and hard location factors are important to all relevant stakeholder groups: visitors, residents, entrepreneurs, businesses and workers.

Method: Systematic Literature Review
Following the research question, aiming to explore the potential of the ecosystem approach in destinations, this article chooses the method of a systematic literature review (SLR) to uncover existing structures in ecosystem research, as well as prevailing research gaps. The SLR can, therefore, collect research recommendations from other publications that also state the need for conceptual clarity across different ecosystem approaches. Research on ecosystems has been shown to be a highly dynamic field during the last five years [48], offering specific potential in tourism in the search for alternative approaches to location and destination management [10]. This SLR aims to frame the research field of ecosystems in tourism and to clarify the various concepts on a theoretical basis.
In comparison to a traditional narrative literature review, an SLR delivers a structured framework for classification and analysis. Without merely stating the quantitative data, such as bibliometric analysis, or picking facts from the researchers' viewpoint, such as a narrative review, an SLR systematically delivers research gaps, definitions, and research characteristics in line with the research question [49,50]. As the SLR has gained attention in various research fields, it is now accepted as an independent research method [51]. In the context of tourism, the SLR was applied, e.g., in articles on adventure tourism [52], film tourism [53], sustainable tourism [54], positive psychology [55], innovation [56], customer satisfaction [57], or sports tourism [58]. As there is still emerging research on ecosystems in tourism, reviews from other business sectors provide an orientation, such as Wurth et al. [59], for ecosystem governance, or Cavallo et al. [48], for understanding local ecosystems. However, these reviews leave space for elaborations on ecosystem research in the tourism industry.
Reviews follow different processes according to different types of systematic reviews [51]. The SLR in this article was pursued as stated in Figure 1, in combination with a rather qualitative approach to content analysis, without complete bibliometric expression. Based on preliminary definitions of the relevant research area, the sections "literature research" and "analysis" provide ten steps to extract data. Therefore, central decisions regarding research fields and filters are made, followed by the definition of queries and keywords, leading to detailed steps on coding and visualization.
research fields and filters are made, followed by the definition of queries and keywords, leading to detailed steps on coding and visualization. In the first step of the SLR, Web of Science and Science Direct were selected as appropriate literature portals. They cover most of the research in business studies and deliver a satisfactory sample size. Critical filters in this query are the English language (1), publications since 2011 (2) and journal articles as sole publication type (3). The focus on articles guarantees scientific quality and availability. This query led to the search results in Table  1, including the respective shares of the search terms on the particular platform. The respective search queries are shown in Table 2 and represent a broad approach to elaborating the ecosystems, including various spellings. In addition to those results, a couple of articles were removed that followed a different ecosystem definition, e.g., ecological ecosystems. The final sample for the SLR comprises 597 articles as a starting point for subsequent analyses. Therefore, the authors decided to apply four screening stages that reflect a funnel in order to concretize the results and to be specific on every stage (Table 2). Starting with 597 articles on the meta-stage, a more quantitative analysis was conducted. Here, frequencies were primarily used to illustrate the research field. On the macro-stage, the focus was set on articles that include the tourism and hospitality industry. From a mathematical perspective, the clusters in this section were calculated using the Pearson correlation coefficient, which measures the strength of the relations between two articles. The calculation across all articles was conducted with NVIVO. With this tourism-related sample, the meso-stage displays research characteristics based on frequencies, whereas more qualitative analyses were conducted on the micro-stage. Therefore, the micro-stage follows a qualitative content analysis that starts by identifying relevant information and clearing up, building categories and structuring a summary. Building upon those procedures, the next section will provide the results for each stage.

Results: Framing Ecosystem Research in Tourism
This SLR has four stages of concretization that follow the funnel in Table 2, starting with the meta-stage and concretizing the results towards the micro-stage. Subsequently, the results of the SLR are displayed on each stage.

Meta Stage: What Role do Tourism and Regional Aspects Play in Ecosystem Research?
The meta-stage reflects a quantitative description of the research field by broadly including all journal publications that were found ( Table 2). This section aims to display the relevance of tourism and regional aspects in the broad research field of ecosystems by referring to publication dates, titles and journals.
Starting with an overview of the publication dates, Table 3 reveals the growth rates since 2017. A specialization of specific economic sectors can then be observed. The titles of the articles provide information about the handled topics (Table 4). Besides the keyword "ecosystem", which is part of every title, it becomes clear that, according to the search filters, "business" and "entrepreneurship" are central keywords. In addition, we can also see that modeling or describing certain cases is an essential part of the articles, while, content-wise, there is a focus on digital/technology and knowledge/education. The term "tourism" (n = 7) is not included in the top findings; however, the further title terms "regional" (n = 32), "city" (n = 9), "local" (n = 8), "spatial" (n = 6), or "urban" (n = 4) definitely also shape the tourism sector as well.  digital  199  role  42  regional  32  knowledge  24  business  183  services  39  social  32  education  23  entrepreneurial  180  studying  39  emerging  30  technology  23  innovation  77  industry  37  platform  30  managing  22  entrepreneurship  75  perspective  36  startup  30  research  22  model  61  approach  34  analysis  28  impact  22  case  59  sustainable  34  framework  27  network  21  development  51  university  34 Source: Own elaboration, articles = 597. When analyzing the journals that published the selected articles, highly relevant journals can be found, such as Technological Forecasting and Social Change (26 articles), Sustainability (17), Journal of Business Research (17), Small Business Economics (14) and Journal of Cleaner Production (12). Together with other journals, ecosystem research is rooted in various disciplines and appears in journals on information and communication technology, policy, business research, or sustainability.

Macro Stage: Which Thematic Clusters Evolve in Tourism Ecosystem Research?
The next stage of our analysis proceeds with a smaller set of articles, as we selected articles with a direct relationship with tourism ( Table 2). These 70 articles are essential to elaborate on the characteristics of ecosystem research in tourism. At first, the macro-stage reveals thematic clusters to capture the current research. Therefore, a cluster-building based on the similarity of full-text words is applied via Pearson Correlations. Figure 2 presents ten clusters, named according to the articles included in a particular cluster. Each cluster was calculated within NVIVO to have similarities and includes at least three articles. Nevertheless, an additional check was necessary to locate statistical outliners. In general, the clusters represent essential components of the ecosystem discussion by including smart and digital systems, knowledge, and education or connectivity. There are also clusters that recognize the role of the spatial system (regional and international) and that of culture and creativity. Although there are different approaches to defining the outcomes of an ecosystem, a couple of articles discover modes of triggering entrepreneurship within the ecosystem, in terms of innovation, sustainability, or economics. While analyzing the clusters, it becomes apparent that smartness has a rich history in ecosystem research in tourism, and this also supports the solid conceptual background within this cluster. Another factor that caused this increase in research is the sharing economy, which is part of the user-centric cluster but also includes various case studies across the other collections.

Meso Stage: To What Extent Have Tourism Ecosystems been Explored?
In terms of their methodology, the analyzed articles reveal a broad spectrum of applied tools and methods (Table 5). However, we can see a focus on qualitative research designs. In addition, there are a couple of articles that triangulated certain methods. Worth  To further elaborate the thematic direction of ecosystem research in tourism, the keywords of the macro-stage articles were analyzed by number of appearances. The focus topics were technology, networks, managing, data, information, development, community, sharing, tourists, systems, or particular research methods, to name just a few.

Meso Stage: To What Extent Have Tourism Ecosystems Been Explored?
In terms of their methodology, the analyzed articles reveal a broad spectrum of applied tools and methods (Table 5). However, we can see a focus on qualitative research designs. In addition, there are a couple of articles that triangulated certain methods. Worth mentioning is the adaption of new methods from ethnography, which provide a different and more user-centric approach. It is also notable that several authors developed concepts rather than studying a field empirically. This was mainly the case in the field of smart and digital ecosystems, as in the solid conceptual work of Gretzel [13,61]. What appears to be underused to date is network analysis, despite its seeming appropriate for the localized and networked concept of an ecosystem. From a methodological perspective, the previous research clearly points to lifecycle or longitudinal studies aiming to capture the development of ecosystems [17,18,62,63]. In addition, present studies should be expanded to different markets and service sectors, as well as in different economic cultures [64,65]. When studying comprehensive and wide ecosystems, social network analyses are perceived as valuable [18,66]. Looking at the scales (Table 6), where research was conducted geographically, helps to reveal certain clusters or gaps. In this regard, it is noticeable that many studies concentrate on Southern Europe, primarily Spain, Portugal or Italy. There are also comparative studies on an international scale that analyze at least two countries. As the ecosystem approach is a very localized one in tourism to date, many researchers focus on cities and specific regions. In addition, in some articles, the focus is on specific service providers or platforms. Future research may include the European Smart Cities, as a set of valuable case studies, showing progress in smart ecosystems. The analyzed articles build upon various research needs and gaps and establish fields for future research. The following paragraph presents these research needs and gaps that mainly include hints on methodological improvements but also questions on the regional impact and further digitalization of the ecosystem.
Ecosystem research in tourism stresses the relevance of the region for the ecosystem and vice versa. Future research in this regard needs to include a variety of stakeholders and the local community [90]. However, ecosystems can provide interesting opportunities for micro-entrepreneurship or promote local networks, which should also be included in the research [17,18]. Furthermore, it would also be valuable to analyze how ecosystems work in rural creative tourism [18] or how external factors shape the development of ecosystems in general [66]. Although ecosystems mainly play a role in local contexts, future research can expand on the local-global continuum of ecosystems [62].
A third research field is based on the interactions that occur in ecosystems. This may be from the tourist's perspective regarding interaction with the tourism service providers [117] or the relationship between DMOs and service providers [19].
Next, research gaps are described around the digital progress in ecosystems. In this regard, the technological development and the usability of machine learning and AI are at the center of the research needs [92,114]. A broad spectrum of experts needs to be involved in the research [103] to carefully balance human-computer interactions and retain trust and privacy [65,114]. The impact of technological progress on the ecosystem needs to be researched further [17].
In addition, further research needs are mentioned, such as the role of p2p platforms [107], the parallel systems of ecosystems [17], an analysis of ecosystem resources [81], policies on resilience, and entrepreneurial capability [122].

Micro Stage: What Are the Specific Drivers for Ecosystem Development and How Are They Characterized?
The final stage of the SLR analyzed the specific drivers of ecosystem development and their characteristics, as well as the clusters that are focused on. This part of the analysis revealed that the success factors of ecosystems have barely been investigated in the literature. The importance of digitization and single digital components for the whole ecosystem has been recognized early on [93]. The availability of knowledge, talent and other resources is also critical for a successful ecosystem; even the nature of the ecosystem itself constitutes its success, as continuous successes and failures and the resulting firm exits, workforce up-skilling and new formations continuously (internally) create and (externally) attract new resources [87]. However, ecosystems, together with local conditions and resources, also contribute to the success of entrepreneurs [62].

Ecosystems: A Definition
Subsequently, the definitions of ecosystems, ecosystems in tourism and the ecosystem components in tourism will be analyzed to capture the central components and potentials and reach a consensus. This will provide a foundation for the development of an integrated concept.
The idea of classifying and conceptualizing business and entrepreneurial environments as ecosystems is derived from biological ecosystems, which encompass the "biotic community, its physical environment, and all the interactions possible in the complex of living and nonliving components" (Acs et al. [46], cited in Eichelberger et al. [42] (p. 320)). This approach was later adopted for the definition of interactions and interdependencies in economic and entrepreneurial environments. Such ecosystems are formed of a number of formal, physical, market and cultural framework conditions, as well as systemic conditions, such as networks, intermediaries, talent, knowledge, leadership and finance.
This has led to the establishment of the "Entrepreneurial Ecosystem", which is defined as "a set of interdependent actors and factors coordinated in such a way that they enable productive entrepreneurship in a particular territory" (Stam and Spigel [123], cited in Bichler et al. [62] (p. 2)). Within entrepreneurial ecosystems, several different actors are of importance. The main actors are entrepreneurs, who are driven by a vision and participate in the industry with their innovative ideas [66]. They are often attracted by local and regional working and living conditions, and can contribute to the economy and development of the place at which they work [70]. Other central actors in entrepreneurial ecosystems are businesses, which often have an entrepreneurial culture and provide resources to other ecosystem stakeholders. The third important actors are organizations and governmental institutions, such as trade associations, research and educational institutions, investors or regulating bodies, which add to the success of businesses and entrepreneurs and provide many of the aforementioned conditions [109].
Similar to entrepreneurial ecosystems, business ecosystems are local networked systems where multiple firms coexist, cooperate and compete; are interconnected and, partly, depend on each other; and form a dynamic structure that can adapt and develop [112]. This interplay of competition and cooperation, which is also referred to as co-evolution, facilitates organizational growth and strengthens the local and regional economy [81]. Hence, both entrepreneurial and business ecosystems with their surrounding local environments are seen as drivers of regional development [62]. Furthermore, some scholars view ecosystems that consist mainly of corporate and government actors and policies as important elements of tourist destinations, alongside their territory, tourism companies and the local community [78].

Ecosystems in Tourism
As a subdivision of both entrepreneurial ecosystems and the tourism industry, tourism ecosystems consider the perspectives and interests of all relevant stakeholders such as businesses, residents, governing bodies and visitors. Among the major reasons for this approach is the impact that visitors of a city have on residents and the residents' feedback as an important tool to support the different stakeholders of the touristic ecosystem [74]. Furthermore, entrepreneurial ecosystems in tourism can also help reshape management models and tourism products and, through entrepreneurial activities, and enable sustainable development in tourism [84] and beyond.
Considering the findings of the SLR, there appears to be no specific definition of tourism ecosystems, as most research focuses on digital and smart aspects that are gaining increasing attention in destinations and tourist environments. The smart urban ecosystem approach is described as a complex urban ecosystem that connects the destination with the smart city [100]. Recognizing tourism systems as smart ecosystems can help to integrate resources more sustainably, increase the understanding of the strategic impact of information and communication technologies along the entire customer journey [117] and meet travelers' need for information and communication, not only before but also during the travel phase [78].
Creating a digital environment and implementing the technological infrastructure into a destination helps achieving a stronger cooperation and increasing the share of knowledge and open innovation between all destination stakeholders [93]. Such cooperation and knowledge exchange also enable the tourism industry to "engage and interact with the public, create conversations, and establish relationships" to deal with new trends and developments that impact society, travel and local communities [85] (p. 75). This, ultimately, leads to "more convenient, safe, exciting and sustainable living spaces for both residents and tourists [ . . . ] and even greater opportunities for new services, business models and markets" [61] (p. 185).
More recently, attempts have been made to combine both entrepreneurial and tourism ecosystems and add aspects such as lifestyle or quality of life to discussions about entrepreneurial ecosystems [15]. A further modification is the concept of Entrepreneurial Destinations that "adds the perspective of living and leisure [and] defines economic roles and activities by highlighting urban attractiveness" [10] (p. 171), which also facilitates the complex coordination, sustainable management and flexible handling of the major stakeholders, namely, entrepreneurs, residents and visitors [10]. Among the core ideas that set entrepreneurial destinations apart from other approaches, are co-concepts such as co-working, co-living or co-experience, which call for an integration of working, living and leisure environments. One way of achieving this integration is the concept of "living labs" that enables dialogue and exchange between all the stakeholders of a place [104].
Given the lack of a definition of tourism ecosystems and the strong academic focus on smart destinations and digital tourism ecosystems that was revealed by the SLR, there is a need for more holistic perceptions of tourism ecosystems and, on a spatial scale, destination ecosystems beyond the focus on technological aspects.

Components of a Tourism Ecosystem
Following theoretical diversity and insights from the SLR, the components that a tourism ecosystem should contain are illustrated in Figure 3. The tourism ecosystem is very diverse and includes the following areas: Quality of Life and Experience (1), Resilience (2), Culture and Creativity (3), Smartness (4), Connectivity (5), Mobility (6) and Competition (7). These components will also be applied to our spatially derived model proposition (cf. Section 5). In terms of understanding the ecosystem in tourism, the results indicate that the "Quality of Life and Experience" and "Smartness" components are central. Therefore, they will be described in more detail. Fabry and Blanchet [100] emphasize that tourism is not only a revenue driver, job creator, or improver of local infrastructure, but also positively contributes to the quality of life of the local population. It is an economic factor that generates significant per capita value in many places. Consequently, tourism creates entrepreneurial opportunities for various stakeholders, e.g., tourism operators, travelers, or residents [70]. However, the current discussions around over-tourism, as well as the COVID-19 pandemic' impact on tourism, indicate that tourism acceptance by the local population is no longer present in some destinations. The understanding of other people needs to be rebuilt and fostered to positively implement tourism with authentic experiences [16]. "A smart tourism ecosystem [...] can be defined as a tourism system that takes advantage of smart technology in creating, managing and delivering intelligent tourist services/experiences and is characterized by intensive information sharing and value cocreation" [13] (p. 560). As this definition emphasizes, smart technologies, such as sensors or big data, are of fundamental importance for the tourism of the future in the course of advancing digitalization. In this context, applied smartness is the responsibility of a wide range of stakeholders-e.g., the government, tour operators and travel agents, transportation providers, restaurants and hotels, local populations, and travelers-with the positive side effect of encouraging public engagement [74]. Furthermore, Pencarelli [78] emphasizes that smartness strengthens competitive advantages, but must not neglect sustainability or negatively affect the quality of life of the local population. Moreover, digital technology, apps, and Big Data must not become a force that creates pressure rather than vacation anticipation.

Discussion
The existing ecosystem approaches focus on entrepreneurial and business environments as well as, in a tourism context, smart and creative systems. A newer approach is that of the entrepreneurial destination, which considers the perspectives of entrepreneurship and leisure. However, a holistic concept, which also considers essential components such as residents' involvement, local networks, touristic and local development, guest-stakeholder encounters or tourism-and service-oriented entrepreneurs, as well as the components outlined in the analysis (cf. Section 4.4.3), was needed. The first attempt in that direction, the Ecosystem of Hospitality (EoH), will be based on the existing ecosystem concepts and the results of the present study. The EoH refers to the spatial scale of destinations.

Model Overview
The aim of the EoH is the integrated development of destinations, locations and living spaces, along with lifestyles and newly arising trends, to both strengthen the customer orientation and underline the dynamics between global trends and local offers, which altogether create new spaces for encounters. Figure 4 reveals the model of the EoH. Context conditions (1) affect the different levels of the destination. As a consequence, an integrated development together with lifestyles (3) has to take place. Accompanied by content layers (4) such as smartness or mobility, some of the future requirements and fields of action (5) for a flexible destination management emerge. Such actions eventually cause a transformation towards a dynamic destination, location and living space, which will affect the resilience of these places. The sequence can vary from destination to destination. The following elaborations are based on the developed model of the EoH.

The Relationship between EoH Actors
As shown in Sections 1 and 4, both integrated destination and location management approaches, as well as ecosystems, incorporate a number of actors and stakeholders, such as residents, visitors, entrepreneurs, businesses and government bodies. The interrelatedness of actors in the proposed EoH can be imagined as concentric circles that each illustrate different, overlapping dimensions. With the EoH, the idea of interconnected actors (cf. Section 2.1) is further developed and the quality of the relationships between these actors is put at the heart of the discussion, with a particular focus on hosts, who can be either tourist service providers or local residents, and guests. This dimension of hospitality is the core nature of tourism, a pivotal indicator of satisfaction, given that both the host and the guest were positively affected by this exchange and experienced some form of interaction and reciprocation. This requires a certain depth of the relationship, which can The EoH is shaped by different layers of quality regarding its requirements and values, which characterize it and make it unique. The innovative spirit, the enthusiasm for pioneering (cf. Sections 1 and 2.3), or the wish for better quality, which is broadly shared across the network, make it an ecosystem in the first place. The EoH differs from other ecosystems, especially in the nature of tourism, by considering the experience of encounters and relationships (cf. Section 2.1) as expressions of humanity. In this context, the encounters allow for a reflection of one's being and doing.
The integration of living space, location and destination fosters alternative concepts and new fields of action, which enable transformation via lifestyle orientation and a crossstakeholder dynamic. Essential for this development is internal and external communication through umbrella branding, corporate branding or destination marketing that unites the diversity of local development in a common brand design (cf. Section 2.1).

The Relationship between EoH Actors
As shown in Sections 1 and 4, both integrated destination and location management approaches, as well as ecosystems, incorporate a number of actors and stakeholders, such as residents, visitors, entrepreneurs, businesses and government bodies. The interrelatedness of actors in the proposed EoH can be imagined as concentric circles that each illustrate different, overlapping dimensions. With the EoH, the idea of interconnected actors (cf. Section 2.1) is further developed and the quality of the relationships between these actors is put at the heart of the discussion, with a particular focus on hosts, who can be either tourist service providers or local residents, and guests. This dimension of hospitality is the core nature of tourism, a pivotal indicator of satisfaction, given that both the host and the guest were positively affected by this exchange and experienced some form of interaction and reciprocation. This requires a certain depth of the relationship, which can only be achieved through a value-based relationship between the host and guest.
An additional factor concerns hospitality, in other words, the quality of encounters, which aims to arouse enthusiasm and excitement. This can occur through the creation of authentic experiences of encounters (cf. Section 2.1) enabled by the experience design. The quality of encounters refers to the quality of experiences (in terms of events, adventures or experience-seeking; cf. German 'Erlebnis') and single moments, whereas the quality of relationships refers to the quality of experience (in terms of knowledge gained; cf. German 'Erfahrung') and the depth and impact of encounters. Referring to the service chains in tourism, the quality of services through professional service providers (cf. Table 4) is essential. This part of the ecosystem is strongly geared toward touristic services and, hence, is of major importance for the EoH. However, the ecosystem can only function well if its touristic parts are in constant balance with its non-touristic parts. The final outcomes of the model affect the quality of life (cf. Sections 2.1 and 2.4) from the perspective of local residents, as well as organizations and institutions, which make essential contributions to the atmosphere of the place.

The Layers and Fields of Action
The requirements for flexible destination and location management are manifold. As highlighted by the elaborations in Section 2.2, the attractiveness of destinations and living spaces is becoming increasingly important. Similar to attractive locations [21], such places combine various attributes that are perceived as attractive. Implementing a variety of these attributes should, first and foremost, enhance the quality of life and experience quality, and even support the understanding of these two concepts as complementary to each other. Entrepreneurs, in particular, are increasingly searching for places with attractive environments for both work and life [70]. This underlines the transformation of especially urban places [40] and, therefore, new concepts are needed to create attractive spaces.
As detailed in Section 2.2, the aspect of human behavior is becoming a focus of urban and rural discussions. Concepts of culture, personality, psychology, and action are being looked at more intensively to better understand society's behavioral factors and to design development perspectives. This means that urban and rural development should not only focus on material aspects such as economic growth, but also on human-centered areas such as well-being [124]. At the same time, strengthening citizen engagement and participation has become a key element (cf. Table 6) [125,126]. The successful involvement of all stakeholders can be realized via open external and internal communication. Conversely, a holistic living space development approach can foster the interest of residents and locals in participatory processes [28].
These EoH components are improved and further developed by smart concepts. Smartness and connectivity play a major role in urban and rural development, as information and communication technologies are essential for the local, digital economy and enable better collaboration between tourism businesses. The smart city approach offers a way forward in terms of urban and rural planning (cf. Section 2.2); thus, they are among the essential components of ecosystems, as outlined in the macro-stage analysis. In the context of digitization, startups play a major role in the attractiveness of a location. This is supported by earlier research that highlights both the growing omnipresence of technology [34], which corresponds with the present research that lists "digital" as the most frequent keyword in the ecosystem literature (cf. Table 4), and smartness, digital systems and connectivity as some of the most explored thematic clusters (cf. Figure 2 and Sections 4.4.2 and 4.4.3).
As an interdisciplinary development approach, the concept of resilience can facilitate the flexibility and adaptability of a region. This was accelerated by the COVID-19 pandemic to achieve sustainable development [38]. The dynamics resulting from resilience foster the creation of new cultural and creative offers that manifest in New Leisure or a variety of co-concepts. The latter contribute to an intensified culture of encounters between local residents and guests (Section 5.2), unfolding an exchange of ideas. These co-concepts are co-created by entrepreneurs, creative minds, guests and locals, and have already found their way into the entrepreneurial ecosystem approach [10]. In turn, these newly arising creative urban spaces may even attract startups, digital companies and highly skilled workforce, which again strengthens the quality of an economic location [21]. The integration of those entrepreneurs and the development of a lively startup scene are increasingly discussed in the context of ecosystems (cf. Table 4; Figure 2). With their innovative and creative aura, such ecosystems complement district development and, together with industrial districts or clusters (cf. Section 2.3), contribute to the attractiveness and development of a place. They also foster productive entrepreneurship, leading to positive reciprocity between entrepreneurs and ecosystems [62].
This increasing urbanization requires new and alternative mobility concepts that are adjusted to both everyday life and leisure. Autonomous mobility or the platform and sharing economy open new opportunities for startups. These have often been described as both important elements of ecosystems and drivers of economic development (cf. Section 4). The foundations of a dynamic location, destination and regional development are laid by the different life models and areas of conflict of urban-rural interfaces.
An efficient governance, the development of regional value chains, the provision of basic services and the consideration of global megatrends are important in the global competition of locations and tourist destinations. The present research detected a lack of research on ecosystems focusing on international competition (cf. Figure 2). Referred to as hyper-dynamic competition by Bieger et al. [127], this approach requires product and process innovation, consideration of milieus and organizational learning [30] and, thus, a further extension of Pechlaner et al.'s [47] destination governance approach. This may be achieved by applying integrative and creative concepts such as hospitality, i.e., a welcoming culture that is formed by the relationships and interactions between locals and guests, and atmospheric design, which refers to the atmosphere and physical qualities of a place.

Conclusions
Based on global challenges, recent trends in the context of tourism and lifestyles, and the role of entrepreneurial ecosystems as drivers of local and regional development, the aim of this article was to conceptualize the existing literature on entrepreneurial ecosystems and derive a holistic, integrated model for destination and location management. This was achieved via a systematic literature review.
Our developed model integrates the destination level, location level and living space level into a joint approach. We found seven components that we regard as essential to ecosystem development in destinations: Quality of Life and Experiences (1), Resilience (2), Culture and Creativity (3), Smartness (4), Connectivity (5), Mobility (6) and Compe-tition (7). They constitute the "Layers" of our derived model (cf. Figure 4). A variety of "Fields of Action", namely, the Startup Scene, Co-concepts, Engagement and Involvement, Ecosystems and Governance, Urban-Rural Interfaces, Well-Being, New Leisure, and Atmospheric Design, illustrate some of the requirements that we found to play a major role in the development of an Ecosystem of Hospitality (EoH), which considers residents' involvement, local networks, tourist and local development, guest-resident encounters and entrepreneurial innovations alike.
By perceiving tourism as a complex ecosystem of hospitality, we call to carefully understand the impacts and effects regarding tourism and how every individual, company and state is situated in this interdependent system. Understanding, learning and adapting are certainly critical competencies for the competitiveness of each component. On the one hand, the ecosystem approach assists in exploring the manifold relations. On the other hand, it helps to overcome crises in more joint and cooperative actions. Reflecting trends in our society, an ecosystem should be both open to innovate and adapt, and critical to traditional, alternative and prospective models.
Our article contributes to the various academic and practical discussions and developments. First, it enhances the understanding of holistic destination, location and living space management approaches, and promotes the idea of their conflation. The different levels of our developed EoH model, the aims, layers, and fields of action, lay an important foundation for the integrated development of destinations, locations and living spaces. Second, the article answers recent calls for adopted tourism and destination concepts in light of overtourism or debates on sustainability and transformation. Third, it supports the increasing academic and professional attention given to hospitality beyond the traditional scope, which is limited to providing fare or accommodation.
From a methodological perspective, our article is limited by its focus on tourismrelated publications. The applicability of the EoH needs to be investigated by gathering primary data. Another limitation is the applied search filters on language, publication date and publication type, as well as the usage of specific literature portals, which may have excluded additional relevant literature from the SLR. From a theoretical perspective, our holistic destination, location and living space management approach is limited by its derivation from destination and entrepreneurial ecosystem concepts. Thus, additional components that are perceived as essential in the context of economic locations or the living space of residents may be further strengthened in our EoH model.
To further explore the potentials, relevance and development of the proposed EoH, future research may focus on the following topics: 1.
The creation of an EoH governance structure; 2.
The role of mobility concepts, both existing and alternative ones, in integrated destination and location management approaches; 3.
The role of new tourism trends, such as recreational or spiritual tourism, in destination and living space development; 4.
The inclusion of and interactions between various local and regional stakeholders in ecosystem discussions; 5.
The role of stakeholder issues and interests such as privacy, data protection or trust, especially in the context of growing digitization; 6.
The consideration of components that are perceived as essential in an economic location or in the living space of residents.
