Cooperation Networks and Embeddedness—The Case of the Portuguese Footwear Sector

The purpose of this paper is to explore the role of embeddedness and cooperation networks in the business internationalization process. To achieve the abovementioned purpose, a qualitative methodology was carefully chosen, through which semi-structured interviews were conducted with ten entrepreneurs of the footwear sector in Portugal, as well as with a head of the national footwear business association. In order to process the data obtained by conducting the interviews, content analysis and data coding through the NVivo software were performed. The results suggest that internationalization is essential for companies in the Portuguese footwear sector. In addition to internationalization helping companies to increase their turnover, it allows companies to grow in a more sustainable way. On the other hand, research also allows us to deduce that networks play an important role in the development of the organizations in question, as they facilitate access to various resources indispensable to this growth. Concerning embeddedness, this aspect presents itself as a facet to which special attention should be paid, considering the pre-eminence that respondents attribute to all variables that help to structure this dimension. The conclusions of this study have theoretical and practical implications, which provide empirical evidence of how the internationalization process can influence the activity of Portuguese companies in the footwear sector. In addition, the results contribute to the evolution of existing knowledge about how embeddedness and cooperation networks facilitate the internationalization process.


Introduction
In the last few decades, the number of companies have that started to expand their area of operation outside their domestic markets has grown [1]. However, when internationalizing their business, companies face several critical decisions: how, where and how much to invest, and how to organize and manage their activity outside their country of origin in order to maximize benefits and minimize risks and losses [2].
Historically, several theories have been developed in an attempt to explain the process by which companies internationalize, such as the Uppsala Model [3,4], the approach born global [5,6] or the Network Theory [7]. Network theory, in turn, helped to understand the basis on which companies develop this process [8,9]. In general, networks can be an alternative mechanism to reduce information asymmetries, and less experienced companies can replace their lack of know-how and their own resources with the knowledge and resources of their contacts, in an international network [10]. A central premise in industry research is the idea that embeddedness in cohesive networks produces positive

The Importance of Internationalization for Companies
In a constantly changing world, with the increasing liberalization of world trade, international expansion has been one of the responses of companies to the growing competition and the various threats that are imposed on them [25].
The international exploration process leads companies to face a broader market, sharing resources between countries and regions [26,27], which can enable them to generate superior profits by specializing work in the global value chain, allowing them to acquire greater economies of scale and become more sustainable [28]. A company's international performance depends heavily on its ability to discover and exploit opportunities in various markets [29,30].
There are several authors [31,32] who have studied, over the years, the driving motivations of business internationalization and foreign direct investment. Hollensen [33] distinguished the motivations for internationalization in reactive or proactive. Among the basic proactive motives that motivate entry into foreign markets are the objectives related to increasing profit and growth, management initiatives, improving technological skills, product exclusivity, economies of scale, tax benefits, and general opportunities that may arise from penetrating foreign markets. In turn, the proposed reactive motivations are competitive pressure, a small domestic market and the lack of domestic demand, the company's overproduction or overcapacity, unconsolidated foreign orders, the possibility of extending sales of seasonal products, and the proximity to international customers [33,34].
On the other hand, organizations encounter barriers in their internationalization process, restrictions that prevent a company from starting, developing, or sustaining business operations in foreign markets [35,36]. These restrictions can be of several types: (i) financial, such as the availability of resources [37], the cost of operations abroad [38] and limited access to capital and credit [39,40]; (ii) management, such as management attitudes [41,42], the lack of international experience and knowledge [37], or difficulties in commitment and partnership [39,40]; (iii) those of the market, such as, for example, environmental perception [41], government regulation, including charge and non-charge barriers [40,43], lack of market knowledge and cultural differences [37] and the strong position in the domestic market [44]; (iv) and industry, such as competition or technological differences [45] and internal barriers to the company, such as access to capital, training and research and development, or product activities, prices, distribution, logistics and promotion of the company abroad [34].
In terms of international business research, the idea of embeddedness is widely used to analyse the activities of multinational companies, in their local environment [46]. Multinational companies combine the advantages of global strategies with embeddedness in heterogeneous, and especially national, contexts. This integration contributes to its innovation, facilitating access to external resources and competences, as well as coordination with internal and external agents [47].

Embeddedness and Internationalization
The concept of embeddedness is rooted in economic sociology, but it has considerable relevance for international management [47,48]. According to Granovetter [49], the economic activity of a company is territorially rooted in its particular social and cultural relations. This concept has been addressed in the scope of investigations related to corporate business networks [15,[50][51][52]. According to this perspective, relationships are difficult to replace, as, over time, both sides adapt their resources and activities to each other in such a way that any relationship becomes unique [51]. According to this research perspective, a company may be inserted in different relationships and networks at the domestic, international, social (personal), and interorganizational levels [53].
Embeddedness can be delineated from a triple perspective [54]: (i) social embeddedness, which is relative to social backgrounds (i.e., cultural, political, etc.); (ii) territorial embeddedness, which considers the extent to which an actor is "anchored" in certain territories or specific places; (iii) network embeddedness, which describes the networking capabilities of entrepreneurs (e.g., the network of actors in which the organization is involved).
Social embeddedness is described as being similar to the organization's 'genetic code' or 'DNA' generated by the background (cultural, political, institutional and economic) that shapes the actions of individuals and organizations in the domestic market [55]. Despite being accepted as an attribute of the company that results from external factors in its domestic market, it is suggested that the analogy made by Hess regarding DNA is somewhat misleading, in that it does not reflect not only the dynamism that reflects the company's changes in its market internal, but also the importance of factors external to the company in the generation of social embeddedness [56]. The company's external network relationships are conducive to the growth of the industry ecosystem as they provide a basis for companies to learn from each other [57]. The embeddedness of companies' internal and external links is positively related to the companies' innovation results [58].
In turn, territorial embeddedness is related to the firm's entrenchment in certain territories or places, since the company absorbs or is restricted by the economic and social activities and institutions with which it shares these places. When the company performs activities in territories that require hiring local human resources or interacting with local social networks, including consumers, the company becomes "incorporated" (or "embedded") territorially [56]. Territorial embeddedness thus emphasizes the location of activities in host countries and involves adaptations to local consumers, local suppliers and real estate markets [59].
Network embeddedness provides organizations with two main advantages: the exchange of high-quality information and tacit knowledge, while also serving as part of the social control mechanism that governs the behaviour of companies [34]. In cross-border activities, less experienced companies wishing to establish credibility in a new foreign market must maintain relations with a host partner to demonstrate local legitimacy and complement their lack of local knowledge [60]. For this purpose, local companies with strategic network positions are preferable, as they are more efficient in collecting resources that will benefit the foreign partner [61].
Former business networks (e.g., customers, suppliers and support institutions) and social networks (e.g., friends, family and former customers) can influence the business internationalization process, helping entrepreneurs to find opportunities in the foreign market [62].

The Role of Networks in the Business Internationalization Process
The importance of networks for the internationalization of companies, especially in the case of small and medium-sized companies, seems irrefutable, considering the existing research on the theme [63,64]. This type of relationship has a strong impact on the selection of the market, as well as the way of entering foreign markets [8]. Companies established in both developed and emerging economies generally rely on networks to seek, discover and explore business opportunities in foreign markets [65]. Networks can help companies gain access to a wide range of resources such as political influence, reputation and mutual trust [66]. Thus, companies internationalize themselves, developing continuous relationships and increasing their commitment of resources between networks [7].
Internationalization is thus seen as a result of multilateral externalization through business and social networks, and its degree can be measured by the positions held by the partners of the network in which the company is. If the partners are very internationalized, the greater the degree of internationalization of the network [67]. Thus, the phenomenon of the company's internationalization can be seen as the establishment and development of positions in relation to other partners belonging to foreign networks [7].
Network theory was conceived on the basis of companies and entrepreneurs. However, this theory can be applied to any organization, be it public or private, with or without profit. According to Aldrich and Zimmer [68], any organization is incorporated in a network that plays a central role in the development of its activity. In general, networks are composed of a group of actors (individuals or organizations) and a set of consortia between actors [69].
In this way, networks between organizations are increasingly considered a channel that allows the passage of skills, knowledge, technology and development [70,71], within and between regions, being considered essential in the process of innovation and economic growth [72,73].
According to Johanson and Mattsson [7], the position occupied by a company in the network defines the set of opportunities to which it has access and constraints to which it is subject, thus giving rise to its strategy. Thus, according to the aforementioned authors, the phenomenon of the company's internationalization can be seen as the determination and development of positions in relation to other partners regarding foreign networks. A company's competitive advantage is then measured by its resources and/or its ability to mobilize and coordinate the resources of others-for example, suppliers, customers, competitors, and R&D centres [7]. Johanson and Vahlne [8] showed that these relationships have a strong impact on the selection of the market, as well as on the entry mode due to the ease with which they identify and explore opportunities.

Depiction of the Portuguese Footwear Sector
The Portuguese footwear industry is defined as traditional and low technology, dominated by SMEs. The new internationalization valuation and sustainability strategies have significantly altered the image and performance achieved. As of 2009, exports increased by more than 55% and grew in almost all important foreign markets [74].
One of the fundamental reasons for this growth in internationalization was, without a doubt, the environmental sustainability imposed by the European Commission. The new forms of production, according to European measures, have thus led to the economic sustainability of companies, and even the regions where they are located [75]. Currently, Portugal is an important reference in the international footwear market, due to the sophistication and creativity of its companies, which offer a wide variety of solutions for their potential customers. According to data from APICCAPS [76], footwear plays a very important role in the Portuguese industrial structure. Footwear production employs approximately 40,000 people, in almost 1500 companies. The sectors associated with the production of components for shoes and leather goods employ more than 7000 people in 389 other companies. In 2018, Portugal produced more than 80 million pairs of shoes, worth approximately 2 billion euros. Internationally, Portugal occupies a particularly high place with regard to the production of leather shoes and is the sixth largest exporter in the world. Footwear also contributes extensively to Portuguese external accounts. In 2018, Portugal exported approximately 1.9 billion euros (roughly 95% of all production) in footwear, which represented 3.4% of the national total of exported products [76]. The Portuguese footwear industry achieved an import/export coverage rate of almost 300%, with a trade surplus of 1.3 billion euros [77].
For reasons of geographical and cultural proximity and consumers' purchasing power, Portuguese footwear exports are mainly directed to European markets, where Portugal has substantial market shares: 4.1% in Germany; 4.3% in Spain; 5.1% in France; 6.7% in the Netherlands and 11% in Denmark. However, in the last decade, important steps have been taken towards market diversification and exports have increased significantly to markets such as Canada, USA, Australia, South Korea and China. Currently, products can be found all over the world: in 2018, they were exported directly to 163 countries on five continents. Table 1 shows the main destination markets for Portuguese footwear exports. Over the 10 years reported, there was a general positive variation in exports, in the order of 47%, with only the United Kingdom registering a decrease in Portuguese footwear imports. On the other hand, Portuguese footwear exports to the Netherlands increased by approximately 70%.
Despite the importance for the Portuguese economy in general, the footwear industry is particularly relevant in the north of the country, where most companies are based ( Figure 1).
The industry has two large production centres (as shown in Figure 1): one in Felgueiras and Guimarães; and the other in Santa Maria da Feira, São João da Madeira and Oliveira de Azeméis. Both clusters are approximately 50/60 km from Porto, the main city in northern Portugal and, therefore, have good accessibility, namely to the sea port and the airport. A third industrial centre is located in Benedita, 90 km from Lisbon, but has a lesser output. In the northern region, 12% of jobs and 6.8% of turnover in the manufacturing industry are in the footwear sector and, for the Portuguese economy as a whole, represent 6.7% and 2.8%, respectively. The footwear industry is therefore one of the main economic foundations in northern Portugal.

Nature of Study
This study aims to investigate the role of embeddedness and cooperation networks in the business internationalization process. To achieve this goal, a qualitative methodology was selected in which semi-structured interviews were conducted with entrepreneurs in the footwear sector in Portugal. As a way of triangulating the information collected, the national footwear business association was also interviewed, and various documents on the sector were analysed. Qualitative methods have been increasingly used in investigations concerning companies because qualitative techniques facilitate the gathering of information, generating results that cannot be measured or quantified [78]. According to Yin [79], a case study is a form of qualitative approach that examines a current phenomenon in its context, especially when the boundaries between the phenomenon and the context are not clearly defined. As a qualitative research, the sample size may be small, since depth and richness are the key elements, with no need to generalize or replicate [80]. Yin [79] believes that qualitative methods should be used when researchers need to carry out in-depth analyses of specific processes, organizational characteristics and/or perspectives or experiences of individuals. Qualitative methods thus facilitate interpretative analysis of information and the production of theoretical generalizations [81].

Case Selection and Data Collection
For the performance of this study and for the selection of cases, the following criteria were used: 1.
Identification of companies in the footwear sector that invested in internationalization; 2.
Selection of companies for convenience: easy access to information; 3.
Companies with different characteristics: despite being companies in the same sector of activity, we chose to select companies with different characteristics, such as size, countries that have internationalized, the market segment.
In this sense, 5 companies were selected, based in the north of Portugal, operating in different sectors of the footwear sector. A convenience sample was chosen-that is, the selection of companies to be interviewed was carried out arbitrarily, premeditatedly-in order to guarantee the obtaining of the desired data [82].
A semi-structured interview was carried out, conducted with entrepreneurs in the footwear sector, in order to obtain accurate and detailed information on the practices of internationalization, networking and embeddedness in this sector. The interviews were carried out between 23 April 2020 and 11 June 2020, and the interviewees were initially informed about their interest, context of application and objectives, as well as being asked for their authorization to record the interview and to record it, as well as publication and treatment for academic/scientific purposes. The interviews were scheduled by e-mail, and their production was carried out by videoconference or in person, with an average duration of 42 min. Table 3 presents a general characterization of the interviewed companies. Through the aforementioned table, it is possible to infer that the organizations presented are all located, approximately, in the two main national production centres (see Figure 1). However, the year in which companies started their activity varies between the 1980s, a fruitful period in the creation of companies in the footwear sector in Portugal, and when three of the five companies interviewed were formed, and 2013, with the start of the activity of Company 1. In terms of the number of employees, the organizations are quite different. For instance, Company 1, not only because it is a relatively recent venture, but mainly because it is a footwear agency, a type of company that usually does not involve a large number of employees, has only 6 employees. All companies interviewed, with the exception of Company 4, which employs 325 people, can be considered micro, small and medium-sized enterprises (SMEs), according to Law no. 372/2007, considering that they employ less than 250 employees. Regarding the segment in which the companies operate, in order to achieve a more diverse set of data, companies from different sectors of the footwear industry were interviewed: a shoe agency, producers of women's shoes, producers of children's shoes and producers of components for footwear and injected shoes. Still, a common indicator for all companies is the percentage of exports. With the exception of Company 4, which has some constraints for operating in different branches (although in the professional footwear section it exports around 90%), all other companies have an export percentage equal to or greater than 98%, which is close the national average of 95% presented in Section 3.1. The countries of destination for the exportation of national footwear are mainly European countries, such as France, Spain, Germany or the Netherlands, the four main export markets in the footwear sector in Portugal that are included in the analysis presented in Table 1. The ease of carrying out trade within the European community and geographical proximity, combined with the high purchasing power of consumers in the countries concerned, seem to be the main reasons that justify this trend. Table 4 provides a brief description of the interviewees' profile. Two people were interviewed for each of the five companies in question, and also a person in charge of the national footwear business association, in order to be able to triangulate the information obtained, both between companies and at the industry level.
The table above shows that the interviewees are mostly male, with an average age of approximately 37 years. Most individuals have higher education, with a strong focus on the areas of Economics and Management, and hold positions of greater hierarchical responsibility in the companies in question. Regarding the experience in the organization, the interviewees have an average of 8 years at the service of the company, with a clear outlier related to Interviewee 2b, who has 33 years on the staff of his organization.

Analysis and Information Handling
The primary data were obtained through individual, semi-structured interviews, and conducted by a script with the questions that were considered important for the study in question. These interviews allowed a collection of more complete and spontaneous responses through the interaction between the interviewer and the interviewee, thus avoiding problems related to the interpretation of the questions asked [83].
The results of the interviews were treated using a content analysis and the organization of encoded data sources with the NVivo 11.0 software, through which it was possible to extract useful and segmented information, which resulted in the creation of tree nodes that label and branch the interviewees' discourse. In cases where the speeches were very dispersed in their content or with the absence of sufficient elements to capture patterns, and due to difficulties in coding, word cloud analysis was used.

The Motivations for Internationalization
According to Ferreira, Serra and Reis [84] and Song and Lee [22], the motivations for internationalization are based on three basic aspects: the increase in sales, the acquisition of resources and the reduction in risks. Dunning [85] referred, as motivations, to obtaining economies of scale, risk and uncertainty regarding the domestic market, growth and maximization of investment returns, sustainability, risk reduction and access to a wide range of resources, both tangible and intangible. Viana and Hortinha [86], in turn, pointed out six reasons to explain the fact that companies seek to expand their scope to foreign markets: increased turnover, synergies related to cost structures, reduced business risk due to market diversification, collaboration with companies and public institutions, market dominance and absolute advantages in terms of resource dominance. In Figure 2, it is possible to observe the main motivations for internationalization mentioned by the interviewees.

In Figure  2, it is possible to observe the main motivations for internationalization mentioned by the interviewees. Through Figure 2, it is possible to see that, unanimously, the interviewees pointed out, as the main motivation for the internationalization of their companies, the reduced absorption capacity of the national market, as it is a small market compared to other European markets, can be seen in the excerpts below:

Company 4B: "[…] the recognition that the national market does not have a great power to absorb products encouraged the internationalization of the organization."
Even so, other factors such as the crisis experienced in the footwear sector when foreign players entered the market, which arose with a type of production with prices that were much more competitive. On the other hand, the high purchasing power of some European countries, with minimum wages exponentially higher than Portuguese and, therefore, with a much higher purchasing power, were also mentioned as reasons for the internationalization by some of the interviewees:

Company 3B: "[…] there is an unabridged process of crisis for footwear and textiles at that time […] that caused the bankruptcy of many companies […]. Many national companies had problems and only those that bet on internationalization survived. […] our market turns out to be the
European one, which is much larger than the national one. We are currently working for a global market, but very centred in Europe."

Company 5A: "[ . . . ] the domestic market, in terms of consumer products, is not large enough to provide a significant sales volume. The average purchasing power of a woman is 5 pairs of shoes per year internationally, while at national level it is only 2 pairs/year."

Strategies to Internationalize
According to Dunning and Lundan [87], the internationalization process is seen as a proactive decision that arises at the initiative of the company itself. As a rule, this decision aims to increase profits, knowledge and consequently diversify risks, thus making the company more sustainable [88]. When a company tries to enter the international market, it is due to the fact that there is high competition in its country of origin, which pressures companies in some way to proceed with the internationalization process [89]. The choice of entry mode is one of the key aspects for the company's international success and depending on the structure, experience and business model, the company can choose different entry modes [90].
In Figure 3, the main internationalization strategies implemented by the companies under study are summarized. competition in its country of origin, which pressures companies in some way to proceed with the internationalization process [89]. The choice of entry mode is one of the key aspects for the company's international success and depending on the structure, experience and business model, the company can choose different entry modes [90].
In Figure 3, the main internationalization strategies implemented by the companies under study are summarized. As shown in Figure 3, according to the participants, there are several strategies for the exportation of national footwear that the companies in question use: visiting potential customers, distributing through wholesales, digital marketing or differentiating their product, examples of which are in the excerpts below: Company 1A: "We have been betting a lot on the part of digital marketing that we think is prevalent today, in order to better expose the company." Company 3A: "[…] we have one or another export that is through distributors, that is, through the country's distributor. It turns out to be direct for the country, but indirect for the end customer, that is, for the distributor and we no longer have responsibility." However, the interviewees almost universally refer to their presence at international fairs, which are quite common in the footwear industry at a global level, driven by several initiatives promoted by the national association of the sector, and also the collaboration with agents, who establish the connection between the producer and the distributor, as the main strategies that allow companies to expose and, objectively, take their product across borders. The success of SMEs going global depends As shown in Figure 3, according to the participants, there are several strategies for the exportation of national footwear that the companies in question use: visiting potential customers, distributing through wholesales, digital marketing or differentiating their product, examples of which are in the excerpts below: Company 1A: "We have been betting a lot on the part of digital marketing that we think is prevalent today, in order to better expose the company."

The success of SMEs going global depends significantly on the formulation and implementation of internationalization strategies. Those strategies could be, among others, in the form of innovation/technology, knowledge or marketing skills [91].
For the companies interviewed, the main strategies are those exposed below: , as this allows to collect contacts and establish connections through individuals with knowledge of their respective markets, which is more economically efficient than market research by employees in those markets." Association 1: "The association has several projects to help companies to be at fairs, in order to promote the image and brands of national footwear, which have been proving essential for national production."

Main Barriers to Internationalization
Some of the highlighted barriers to the possible exploitation of foreign markets are the insufficient self-financing of companies, the weak productive capacity, the lack of qualified human resources, the poor knowledge of foreign languages and markets, and the fact that there are no links or partnerships in the foreign markets [92]. Hollensen [93] divided these barriers to internationalization into three types of risks: market risks (e.g., competitive difficulties in the face of competition on the foreign market, cultural and linguistic differences, etc.); commercial risks (e.g., exchange rates, etc.) and political risks (e.g., control over trade (taxes), restrictions on foreign markets, etc.). According to Figure 4, it is possible to verify the main barriers identified by the interviewees in this study. their respective markets, which is more economically efficient than market research by employees in those markets."

As can be seen from Figure 4, the main barriers to internationalization pointed out by the interviewees are varied, from cultural differences to geographical distance or linguistic differences. However, the customs duties applied by some countries appear to be one of the biggest obstacles, since they add a substantial cost to the product.

However, the customs duties applied by some countries appear to be one of the biggest obstacles, since they add a substantial cost to the product. Combined with both national and international bureaucracy in the business process, they can prevent, or at least hinder, certain commercial exchanges. Ayden et al. [94] argued that the lack of the imposition of costs/taxes in internationalization as one of the whys and wherefores that impact the decisions regarding international activities. As pointed out by interviewees, these are, indeed, some of the barriers of internationalization in the footwear industry: Although bureaucracies and customs fees are presented as significant barriers by the interviewees, the biggest obstacle that emerged from the interviews carried out is related to competition from countries with extremely cheap labour, which manage to produce at prices impractical at a national level, as can be seen from the excerpts below: Company 1B: "There is also the difficulty for us, the Portuguese market, to fight with other markets, such as Morocco, Albania, Romania and this [ . . . ] creates a problem in terms of target, prices to reach." According to Rendón and Moral [95], the footwear industry is suffering the consequences of the opening up of trade which favoured the importation of Chinese products, whose lower prices have led to the departure of many companies.
Company 2A: "Right now, in the footwear sector, the biggest barrier is perhaps competition. Especially in terms of prices, competing with countries where labour is cheaper, and thus being able to make prices more competitive, has less market share."

Main Benefits of Internationalization
Contractor [96] pointed out, as some benefits of business internationalization, the exploitation of economies of scale and scope, the diversification of risks, the reduction in costs and access to knowledge and learning about the international environment. The hypothesis related to "learning through export" in the international economy shows that contact with international buyers and competitors generates learning effects and that international competition forces companies to be more efficient, stimulates innovation and contributes to their sustainability [97,98]. Considering Figure 5, it is possible to observe the main benefits of internationalization recognized by the interviewees in the study. competition from countries with extremely cheap labour, which manage to produce at prices impractical at a national level, as can be seen from the excerpts below: Company 1B: "There is also the difficulty for us, the Portuguese market, to fight with other markets, such as Morocco, Albania, Romania and this […] creates a problem in terms of target, prices to reach."

Considering Figure 5, it is possible to observe the main benefits of internationalization recognized by the interviewees in the study.  From Figure 5, it is possible to deduce that the main benefits of internationalization for companies, pointed out by the interviewees, are different, but are based on a general basic benefit: growth of organizations, whether financially, in terms of sales, or in terms of the quality of the product designed and the work carried out in general. This growth, exponential in most cases, would not be possible if companies did not venture into foreign markets, as these allow organizations to reach a much wider audience and, above all, gain a much higher purchasing power. The excerpts below prove this perception of growth on the part of the interviewees: . ] the effortlessness of growing the business faster and more sustainably. It is necessary to internationalize in order to have a company with a higher turnover. [Internationalization] it also raises the quality standards of the company, since working with large international groups, the requirement is different and perhaps that is why not any company makes the leap towards internationalization." In fact, based on the logic of embeddedness in relationships, the relationship investment, as internationalization, for instance, can create a more integrated exchange relationship, which is a strategic resource for any company [99,100].
Company 4A: "The increase in the volume of work and the company's affirmation in the international market that allows us to work with major brands and have demand from others." The interviewees also point out that the diversification of markets and consumption habits, resulting from the internationalization process of their companies, allows them to distribute business risk and international recognition of the company, which may afford them opportunities that they would not have if they only had access to the domestic market.

The Territory
The territory is a decisive variable to explain the economic dynamics alluding to different spaces. The historical and cultural circumstances and socio-economic particularities of the different regions play an important role, and their diversity largely explains the differences in the development trajectories of companies [101].
It is common to practically all interviewees that the territorial proximity of their organizations to variables such as labour or raw materials facilitates their growth, even driving the creation of specialized training initiatives in the host regions. The excerpts below reflect these opinions exactly: The notion of proximity is part of a commencement of economic reality, as well as social reality, which is essentially relational. It refers both to the separation, economic or geographical, of the actors, holders of different resources, and to the relationships that unite them (and/or separate them) in solving an economic problem (producing a good, technological innovation, etc.) [102].

The Social Environment
The perspective of the social environment in terms of embeddedness views organizations as social contexts, through which members are linked to each other in terms of "relational ties" and "emotional connections", and these ties and connections are the basis on which individuals decide their courses of action [103]. These social ties can shape perceptions, motivations and, therefore, as mentioned, the action [49].
Considering the interviews carried out, it is possible to perceive that the relational ties and emotional connections here referred to-that is, the social environment-have an influence on the scope of organizations, whether these are family connections, for example, as is possible to deduce through the excerpt below: Association 1: "There are several companies, namely the larger ones, which maintain close cooperative relationships with other companies, which allow them to correspond, sometimes, to large orders. Smaller companies work as subcontractors, and help to respond to these orders."

Discussion of Results
In general, it is agreed that the internationalization process has a high importance for companies in the footwear sector, as well as the domestic connections that facilitate this process. According to the interviewees, the internationalization process is indispensable for the growth and sustainable development of their companies, taking into account the small absorptive power of the national market.
"The footwear sector is currently one of the most internationalized, or extroverted, as we usually say, sectors of the Portuguese economy. We export, on average, more than 95% of what we produce. So, in general, we can say that everything we produce is for export." (Association 1).
This internationalization is achieved, fundamentally, through international fairs dedicated to the sector, which promote the contact of organizations with potential foreign customers. In this context, collaboration with agents also takes on some relevance, since it allows companies to access privileged contacts and facilitates, in most cases, the entire process. On the other hand, the main barrier to internationalization pointed out by the interviewees is related to competition from countries that are able to offer more competitive prices, mainly due to an exponentially more economical workforce, and that are able to produce at impractical prices at the national level. As pointed out by Leonidou [35], scarcity in information, low pricing, consumers' customs, and political-economic factors (either in the country of origin or overseas) are aspects that hinder exporter behaviour. In contrast, internationalization seems to bring a central advantage to organizations, according to the entrepreneurs interviewed, generating growth at various levels (in financial terms, product quality, branding, etc.). In effect, Ayden et al.'s [94] results show that the internationalization activities of firms are influenced by the host country market conditions. Less or moderately competitive markets are more favourable to the internationalization of firms than more competitive markets.
Regarding the role of embeddedness in the exploration of foreign markets and the three variables under study, the territory, the social environment and the cooperation networks seem, equally, to have consensus in the group of interviewees. Both the territory in which the companies are located and the proximity that this location offers to aspects such as labour and raw materials such as the social environment, in the form of cultural or social connections (e.g., family background), are reflected in the way the company's activity is conducted, which includes a greater or lesser tendency to internationalize the business. The study of Propris et al. [113] disclosed that the Veneto-Timisoara case shows three things: (a) district companies internationalize their productive activities very differently from multinational companies, in that they tend to replicate the systemic model abroad, suggesting that companies are aware of the benefits of the usual location/agglomeration/external savings; (b) the relocation coincided with the internationalization of the value chain with only a few functions transferred abroad, which generated strong socioeconomic links between districts; (c) the governance structure of the inter-district network tends towards a hierarchical form (management network) due to the asymmetries of competences and, therefore, of powers between companies. With regard to cooperation networks, all interviewed agents agreed that networking plays a major role in the expansion of their external ventures, as in addition to facilitating this type of initiative, it provides important international opportunities, which without this type cooperation would probably not appear, or, as mentioned, would be more difficult to achieve.
The Network Theory postulates that the internationalization process of an organization develops through the relations that it establishes with all the actors involved in the development of its activity. Networked relationships allow for cost savings, more in-depth knowledge of international markets, and reduced transaction costs or economies of scale through joint research efforts [7]. For example, Yli-Renko, Autio and Tontti [114] demonstrated that the ties created between companies favour international growth through the creation of greater technological knowledge. Zhou, Wu and Luo [19], in turn, suggested the importance of social networks in explaining the relationship between internationalization and organizational performance [115]. Dogbe et al.'s [116] results, for instance, reveal the importance of network embeddedness on innovation performance.
Although there are some disparities between the cases under study, even considering that the companies in question are different in terms of the market segment in which they operate, it is possible to say that internationalization is practically indispensable for companies in the footwear sector that want to grow and expand their business. It is also possible to infer that networks play an important role in their growth and development, as they make it possible to boost sales, obtain different resources and share experiences and knowledge. In turn, embeddedness, in the form of the variables under study, represents an aspect that must be considered, bearing in mind the preponderance that the interviewees attribute both to the territorial dimension and to the social environment and cooperation networks.

Conclusions
With this study in mind to understand the role of embeddedness and cooperation networks in the business internationalization process, a qualitative methodology (case study) was used for companies in the Portuguese footwear sector.
With the analysis of the interviews carried out, it was possible to conclude that internationalization is fundamental for companies in the footwear sector, being the main process through which organizations sell their produce. It was also possible to perceive that the environment that involves companies, whether in territorial, social or cooperation networks, is effectively relevant to the business internationalization process, influencing the way organizations are internationalized. In view of their proximity to the resources necessary for internationalization, cultural and social connections to their place of origin and, in a superlative way, the access they may have to cooperation networks that, according to the interviewees, play a leading role not only in the genesis of the international processes of but also after entering foreign markets and, therefore, throughout the period in which the exploitation of these markets continues.
In theoretical terms, this study contributes to the literature of the scope in question, namely with regard to a better understanding of domestic relations in the internationalization process, as well as the role of embeddedness and networks in the internationalization process of organizations. It also makes possible the identification of possible future investigations in this matter, thus contributing to its progress.
In practical terms, it is expected that this study will help policy makers with regard to the creation of local regulations for organizations in the footwear sector, bearing in mind the importance of embeddedness, related to tax benefits for organizations that cooperate internally and use nearby resources, contributing to the growth of the regional economy and, more extensively, to the growth of the national economy. It is also hoped that the investigation will allow companies, as responsible entrepreneurs, to demonstrate that the development of networked businesses can bring tangible benefits to their organizations.
Throughout the study, some limitations were found that must be considered both in the interpretation of results and in future investigations. The first limitation identified is related to subjectivity. Despite taking all the precautions recommended for this type of investigation, qualitative studies always show some subjectivity in the analysis of results and in the coding and categorization system of the interviews. The second limitation has to do with the fact that the study sample was obtained by a convenience sample. Finally, the last limitation is related to the fact that the study focuses only on one sector, which despite being the most representative at national level, does not represent all industrial activity.
The limitations previously presented can be a starting point for future investigations, thus contributing to the development of the existing literature. In this context, it would be important to extend this study to a perspective of comparison between companies that internationalize their activity mainly to the European market and organizations whose international activity is more dependent on
