2.1. Stakeholder Theory
The stakeholder is defined as “any group or individual who can affect or is affected by the achievement of an organization’s objectives” [
28]. A team of stakeholders is conventionally deemed to be in the form of a number of behavioral parties confined in the wider system of tourism. Such parties include specific individuals namely tourists, operators, inhabitants, and people with regulatory jobs [
29]. Within the scope of literature corresponding to the subject of tourism, a greatly endorsed matter consists of stakeholders’ recognition and participation in decision-making activities regarding tourism management [
29,
30]. As proposed by one of the foremost advocates of the Stakeholder Theory, Freeman [
28], toward the efficient management of businesses, the connections among the various corresponding components are required to be taken into consideration by the managers of these businesses. As a result, the interests of stakeholders and success in business respectively constitute the fundamental independent and dependent constructs in the Stakeholder Theory. Furthermore, according to this theory, the motivation behind the participation of legal individuals or parties in an organization’s activities is to gain relevant advantages, and there is no clarity in the legal stakeholders’ priority of interest [
31].
The utilization of the Stakeholder Theory is relatively novel and restricted to a great extent in the area of tourism. On the whole, matters such as stakeholders’ recognition and the extension of cooperation in the process of planning and development in regard to tourism are mainly concentrated on [
32,
33]. In a survey carried out by Easterling [
32], an analysis took place on the perceptions of the inhabitants of a well-known tourist attraction regarding the included stakes. According to the results of this study, founded on the type of residency, a minimum of three kinds of stakes belong to the constituents of these groups which consist of equity, economics, and influence. As suggested by the Stakeholder Theory, in order to achieve the requirements, set by a triumphant development, stakeholders’ interests and perceptions need to be considered [
34]. This is why the participation of a community as a whole in the development of tourism from the angle of the Stakeholder Theory has only been analyzed by a limited number of research works [
29,
32]. Moreover, the inclusion of residents as stakeholders in the sustainable development of tourism has been studied by Nicholas et al. [
35]. These scholars delved deeper into the extant connections among the perceptions of residents, participation of communities, and the sustainable development of tourism. Hence, the corresponding findings yielded the discovery of a significant positive relationship between the perceptions of residents and community participation. Moreover, for the purpose of the efficient collection of all related resources, strategies, and capacity in regard to “multi-stakeholder systems to evolve and transform for survival and success”, the significance of cooperation among numerous stakeholders is highlighted by the Stakeholder Theory [
36]. Additionally, with the aid of the Stakeholder Theory, the diverse state of positivity and negativity regarding the perceptions of residents became the subject of analysis in a study carried out by Rasoolimanesh and Jaafar [
14]. This study also examined the impacts caused by this heterogeneity of perceptions on the encouragement and involvement of the residents concerning the sustainable development of tourism in the Lenggong Valley World Heritage Site in Malaysia. As such, their findings indicated that the residents’ support and involvement in tourism growth is positively influenced by their positive perceptions.
2.3. Support for Sustainable Tourism
With reference to tourism development, one factor which plays a vital role is sustainability. To a certain extent, this is because economic growth consists of no other configuration with such a large number of ‘far-reaching tentacles as tourism’ [
42]. With regard to sustainability in the development of tourism, abundant statements are provided in literature in the area of tourism which clarify its exact meaning. According to one frequent perspective, toward the optimization of the incessant economic achievability in tourism growth, host communities need to be strengthened in quality, and natural and artificial environments need to be preserved [
43]. Some scholars also revealed that the development of tourism depends on how stakeholders perceive the quality of health [
44].
Furthermore, through the optimization of domestic benefits in the economy, security of natural and man-made environments, and the provision of tourist experiences of excellent quality, it is a goal for community tourism’s sustainable growth to enhance the residents’ standard of living [
1]. A long-lasting economic connection among communities in tourism destinations and the corresponding industries stands in need of being reached by sustainable community tourism. Moreover, during this procedure, the related negative impacts on the natural environment must be reduced to a minimum, and the destination communities’ socio-cultural welfare must be upgraded. In this regard, all ethnic duties as well as rules of decorum must be taken into consideration by various stakeholders in the community, comprising all elements taking part in businesses concerning tourism, namely tourists, hosts, tour operators, and governments [
25,
45]. In tourism-related sectors, sustainable development has been a major subject of discussion. This is due to the fact that through this kind of development, the requirements of tourists are satisfied, economic growth is liable to be strengthened, physical environments are secured, residents’ living quality is enhanced and, lastly, future opportunities are improved by ensuring environmental quality and the development of tourism coexist [
46]. As a result, a vital tool for sustainable management is in the form of tourism growth in communities [
47]. Furthermore, factors such as support in local communities as well as development sustainability are influenced by the growth of tourism [
35,
46]. Simply put, the issues corresponding to the host community of a tourist attraction have a deep impact on that destination’s sustainable development [
48]. Hence, subsequent growth in tourism is supported by residents cognizant of an increased number of positive effects on tourism, whereas it is less encouraged by those more aware of the negative impacts of tourism rather than its positive ones [
49].
During the 1990s, the focus of scholars turned to sustainability in regard to tourism development. In this path, a more comprehensive strategy was needed in order to combine the perceptions of numerous stakeholders, residents included, concerning the analysis of the set of positive as well as negative effects caused by tourism in various types of tourist attractions, namely in economic, socio-cultural, and environmental areas [
45,
50]. Moreover, through the investigation of particular variables leading to the prediction of residents’ perceptions about tourism in divergent communities, research in this field has employed more minor methods as compared to the major ones used previously [
50]. In the recent millennium, a revived interest in the perceptions of residents regarding tourism development, particularly corresponding to the existing economic and social influences, has risen as a result of the novel pursuit of sustainability [
34]. On this subject, a more vital role can be played by local inhabitants as well as local businesses in the growth of various tourist attractions since collective and business interests impact politicians’ viewpoints to a great extent.
To conclude, with the goal of sustainability in tourism development, an unsegregated system of decision makers is constructed consisting of numerous elements such as tourists, native residents of tourist destinations, related businesses, and the government [
34,
51].
2.4. Hypothesis Development
Wallace and Wolf [
52] have defined solidarity as an individual’s sense of identification with a different individual which acts as a form of emotional reinforcement between the two people. Moreover, according to the study of Hammarstrom [
53], the related connections among individuals are distinguished by their observed emotional intimacy and level of contact which is included in solidarity, perceived economic benefits and costs corresponding to tourism are severely impacted by the personalities and viewpoints of the local residents of tourist destinations regarding their communities and received tourists. These factors can also heavily affect an inclusive reinforcement in the sustainable development of tourism. Toward a more efficient comprehension of the emotions of residents concerning tourists, a theoretical framework was devised in a work of research carried out by Woosnam and Norman [
54], which was constructed based on materials written by Emile Durkheim. Originally progressed through the research of Woosnam and Norman [
54] and later evaluated by Woosnam [
55], emotional solidarity is classified as the most up-to-date theory on the subject of relationships among residents and tourists.
Furthermore, Woosnam and Aleshinloye [
56] found that frequent emotional solidarity of a positive nature contributes to the promotion of this sort of intimacy between the tourists and residents. Several tourism studies have well-documented associations among emotional solidarity toward tourism stakeholders and their support for tourism development [
57,
58,
59]. This is because the central of the emotional solidarity approach is that people who feel bonded emotionally to visitors are more likely to appreciate the perceived benefits which tourism brings to their communities [
60]. Prior literature empirically confirmed the relationship between emotional solidarity, individual perception, and attitude [
61]. Erul et al. [
57] found that residents’ emotional solidarity is an important determinant in predicting their perceptions toward tourism development. This is why friendships are born among the residents and tourists between whom emotional solidarity is developed and thus, the residents are more strongly enabled to perceive the resulting benefits and determine how the development of tourism impacts their communities. Thus, the hypotheses below are formulated:
H1. A positive relationship exists between the degree of emotional solidarity in stakeholders and perceived economic benefits.
H2. A negative relationship exists between the degree of emotional solidarity in stakeholders and perceived costs.
As observed from literature in the area of stakeholders, an amount of controversy regarding the level of specificity in attitudes with reference to behavioral groups in stakeholders continues to exist. Following this supposition, four noteworthy perspectives regarding tourism stakeholders are stated in the study by Byrd et al. [
62], which are tourists, residents of tourist attraction sites, business operators, and native representatives of the government. As outlined by Hardy and Pearson [
29], the attitude sharing among groups of stakeholders with regard to tourism’s positive and negative impacts acts as benefits and costs accompanying extreme inconsistencies in attitudes over groups corresponding to issues of other types. Despite the frequent examination of the attitudes of residents on the subject of tourism in a large number of studies [
14,
34,
63], either in a general sense or in relation to a community in particular, the connection between the attitudes of residents and perceived benefits and costs remains to be explored. Positive attitudes regarding tourism are assumed to lead to the perception of various benefits in tourism development. Hence, the following hypotheses are provided:
H3. A positive relationship exists between the stakeholder’s attitudes and perceived economic benefits.
H4. A negative relationship exists between the stakeholder’s attitudes and perceived costs.
Based on Grzeskowiak et al.’s [
64] definition, community commitment is the extent to which residents identify the community as their own, feel faithful to it, and would not move out of the community at will. In parallel, this concept is specified by McCool and Martin [
50] as “the extent and pattern of social participation and integration into the community, and sentiment or affect toward the community”. Furthermore, there is certainty in the existence of community commitment once a feeling of belonging is felt by the local residents of a community and they enjoy being involved in community activities as well as when they feel spiritually attached to other members of their communities and experience a sense of comfort while sharing divergent viewpoints with them [
21,
65]. Moreover, Hibbard and Karle [
39] stated that the native residents’ commitment to their communities enables them to handle given opportunities, come up with answers to different problems, and enhance responses regarding their communities in a more efficient manner. Therefore, the following hypotheses are formed:
H5. A positive relationship exists between stakeholders’ commitment and perceived economic benefits.
H6. A negative relationship exists between stakeholders’ commitment and perceived costs.
By way of deliberating on various tourism-related matters in regard to the economy, society, culture, and the environment, community residents choose if they would like to become dependent on tourism’s benefits and costs [
49,
66]. The effects of tourism stakeholders’ perceptions on support for tourism development have been extensively investigated [
14,
67]. For instance, most previous literature found that support for the development of tourism is positively significantly affected by perceived benefits [
23,
68]. However, a significant and negative impact is observed by perceived costs in this regard [
34,
49,
69]. It is clear to state that the precedent variables concerning the support for tourism development among residents are perceived benefits and costs [
26,
34]. Hence, inspired by previous empirical studies, the following hypotheses are set forth:
H7. Perceived economic benefits directly and positively impact residents’ support for sustainable tourism development.
H8. Perceived costs directly and negatively impact residents’ support for sustainable tourism development.
The influences of emotional solidarity within the framework of tourism are illustrated by a variety of studies. A few examples of such impacts consist of the perceptions of residents regarding tourism and their corresponding implications on the support for tourism [
56,
58,
60], support for the development of tourism [
21], economic benefits [
70], and specific patterns distinguishing the expenses of tourists in given tourist attractions [
56]. According to several sources, the aforementioned areas have proven to be connected to emotional solidarity. For instance, according to Woosnam et al. [
56], the contributions of the tourism industry to the communities involved is heavily predicted based on emotional solidarity. This is why friendships are created between the tourists and the residents of their destinations among whom emotional solidarity is formed. Hence, the residents become better capable of identifying how their communities are affected as a result of the growth of tourism [
56].
In this regard, in a study by Woosnam et al. [
56], emotional solidarity and the following effects of the Kolache Festival were examined considering the local residents of Caldwell, Texas. The finding indicated that a major level of variation in the residents’ perceptions about the consequences of hosting this festival can be justified by emotional solidarity [
56]. To be more precise, a positive connection exists between benefits and each factor corresponding to emotional solidarity and a negative connection exists between costs and each factor of emotional solidarity. In addition, the attitudes of residents in Galveston County, Texas, regarding sustainable tourism development was the subject of evaluation in the research of Woosnam [
54], signifying that all factors related to emotional solidarity are strongly liable to speculate the attitude scale and indicators connected to the impacts of tourism, including support for the sustainable development of tourism as well as contributions made by tourism with respect to the community. Hence, it can be reliably concluded that a positive perception regarding the impacts of tourism can be found in residents who are more emotionally involved with tourists which, in turn, leads to support for sustainable tourism development. Despite a noticeable development in tourism literature on emotional solidarity, the relationship between emotional solidarity and support for sustainable tourism development within communities is underexplored. Former research focused on the theory and scale of emotional solidarity [
55]; there has been no research to investigate relationships among emotional solidarity, the positive or negative perceptions of stakeholders, and support for the sustainable development of tourism in literature in the area of tourism in Iran. Considering the previous discussions, the following hypotheses are presented:
H9. Perceived economic benefits mediate between emotional solidarity and support for sustainable tourism development.
H10. Perceived costs mediate between emotional solidarity and support for sustainable tourism development.
Additionally, according to McGehee and Andereck [
11], a negative attitude toward sustainable tourism development may be formed among residents not employed in the tourism industry. This can be due to the fact that such residents are not fully informed about the benefits of tourism and, therefore, consider the growth of tourism to be environmentally unfriendly. Thus, as mentioned in the study by Hung, Sirakaya-Turk, and Ingram [
71], in order to more efficiently promote the planning and sustainable development of tourism, the attitudes of the corresponding residents are important to take into account. Naturally, residents are highly expected to comprehend the benefits as well as the costs involved in tourism. In this regard, the benefits of tourism consist of the creation of job titles, higher salaries, enhancement in extant facilities and infrastructure, and opportunities to come into contact with new and compelling individuals. Moreover, the costs resulting from tourism include overcrowding, increased expenses, higher taxes, etc. In a large number of studies, the degree of support in residents regarding the growth of tourism is strongly connected to such positive and negative attitudes [
72]. More specifically, as indicated by several empirical studies, economic benefits of tourism are heavily and directly impacted by attitudes with respect to support for the development of tourism [
9,
17,
73]. Thus, the following hypotheses are formulated:
H11. Perceived economic benefits mediate between the stakeholders’ attitudes and support for sustainable tourism development.
H12. Perceived costs mediate between the stakeholders’ attitudes and support for sustainable tourism development.
Furthermore, as highlighted in the study of Liu, Tzeng, and Lee [
74], toward reaching sustainable tourism development and obtaining benefits from the tourism industry, local residents of tourist attraction sites are highly depended on by their governmental authorities to display commitment to their respective communities. On this subject, a single paper by Gursoy et al. [
25] stated that through the sensed satisfaction of local residents with their communities, their perceptions regarding management-related practices directly and indirectly impact their support for additional development in tourism. Nevertheless, no significant influences are distinguished from economic and environmental factors on commitment to the community. In addition, commitment to the community serves as a powerful predictor of support regarding additional development in tourism. As a result, the hypotheses below are created:
H13. Perceived economic benefits mediate between stakeholders’ commitment and support for sustainable tourism development.
H14. Perceived costs mediate between stakeholders’ commitment and support for sustainable tourism development.
