1. Introduction
Seeking low costs and advantages through a cheap and available workforce, better government policies, and interesting resources, some companies that once produced in developed countries began to internationalize their industrial production, transferring it partially or completely to developing countries. This movement is known as offshoring. However, a new global movement emerged, and companies are now returning to their countries of origin for their activities and production units due to several factors, such as changes in regulations, major economic differences between countries, instability in the exchange rate, and greater competitiveness for scarce resources [
1].
In a global scenario, the return of the entirety or part of production to the original country involves factors of outsourcing and make-or-buy decisions. The supply resumption decisions and reevaluation of resources’ locations can lead to inadequate quality of the delivered products, theft of intellectual property, growth opportunities, the brand value, the approach to the final consumer, and other issues [
2]. In turn, strategic decisions regarding resources and organizational units are involved in the relationship between supply chain management’s scope and the decision-making studies on the locations of production units. Finally, location decisions or even resource allocations have a close relationship with inventory and production issues [
3]. This movement, known as reshoring, represents a planning and reorganization of the productive and distributive units of supply chains. This process faces challenges, such as the tendency to increase costs; therefore, despite its importance for the global context, the topic is still poorly studied [
1,
2].
There are three attributes that make reshoring an even more complex process: the geographical or physical distance, which makes it difficult to measure and control the business; cultural distance because of regional and historical differences in the countries involved; and the dispersion distance, aggravated by the management of multiple locations in multinational companies [
4]. In addition, sustainability is a critical factor of success for the business together with cost and profit evaluation decisions and potential risk sites, with includes mathematical solutions [
5]. The literature on outsourcing also shows the complexity of controlling and coordinating costs [
4].
The current industrial context changes the business models and internal operation strategies, so network partners create new markets with value proposals based on the immersion of new technologies: Industry 4.0 [
6]. Known as the fourth industrial revolution, the benefits of new technologies have become the subject of many studies, both on their technical efficiency and in relation to organizational issues, including their ability to transform supply chains [
7].
Despite the importance of new technologies for management, most studies are of a technical nature, with a lack of work on management support for the implementation of the technologies, that is, valid business models and strategies that precede the choice of the most appropriate technologies and their expected results [
7]. A new research agenda suggests studies on logistics that involve organizational restructuring, role changes, reverse logistics, and resource efficiency in traditional models [
8].
Therefore, there is a demand for research that relates to risk management and on-demand solutions, in addition to the regional and national context regarding the stimulus and incentives to digitize and influence sectors and the sizes of companies [
6]. Regarding the resilience of supply chains, certain themes, such as the role of human resources and technology, need to be further explored in order to fully understand and promote resilient supply chains [
9]. These aspects warrant deeper investigation to uncover their potential impacts and to identify strategies for fostering resilience within supply chain management. In South America, there is great interest in the available resources, but an increase in the future perception of risks of disruption to the supply chain [
1].
Given this context, it has become essential that enterprises and multinational companies identify the main factors in the reshoring process and how the new technologies can favor their strategies. The objective of this research is summarized by characterizing the literature on location strategies and the reshoring movement in the context of Industry 4.0.
To better understand the reshoring movement, an SLR (systematic literature review) was conducted in order to comprehend the academic production related to the topic and to thoroughly identify and integrate research that is relevant, employing structured, transparent, and reproducible methodologies at each stage of the process.
Industry 4.0 is defined as a set of highly integrated smart factories, where individual products are made sustainably in a mass production format, meeting the demands of the globalized market [
8]. Germany was the pioneer and has responsibilities regarding its regional productive sectors, as well as other global sectors, such as those involved with implementation and technological development through support and solutions in the field of information technology. This transformation will occur gradually with the integration of current technologies, the commitment of technological and informational industries, and new regulations and international standards [
10].
Industrial revolutions have been marked by changes in the methods of producing, relating, and creating value. Since the advent of mechanization of production, the use of electrical energy; electronics; and, more recently, the internet of things, cloud computing, mining, etc., has increased [
7]. Again, with Industry 4.0, there will be changes in the ways of producing, relating, and creating value, that is, there will be changes in the methods of negotiating and in information systems through integration between areas, economic sectors, industries, and productive and value chains. In addition, it transforms and creates models and designs of information systems [
11]. Amid the challenges of the new industry, companies must adapt and innovate in their products, processes, and distribution to generate value and speed for production chains [
12].
Industry 4.0 trends include disruptive technologies, customized mass production, and human and environmental integration into industrial systems [
8]. Industry 4.0 also provides opportunities for enhancing food logistics through the adoption of Industry 4.0 technologies. These technologies offer the potential to decrease costs and time while simultaneously ensuring the quality of food products throughout their transportation within the supply chain [
13].
A study of stable companies and startups revealed different purposes for the use of technology: the tendency to focus on services or products, the use of market platforms or ecosystems, and the establishment of support for businesses and new products. All of these requirements are aimed toward supply chain innovation and the generation of value for the final consumer, as well as the creation of more effective relationship networks [
6].
The constant global changes demand new strategies and business models, as well as quick decision making, in business administration. Contributions to the literature involve adding new theories and methods that are appropriate for these changes and updating researchers in the areas related to the theme for future research agendas. Ref. [
6] proposes this relationship between the resources and units’ allocation decisions (represented by the reshoring movement) and supply chain management in a new context, in the scope of organizational capacity, which includes technological resources, equipment, and machinery.
The decision-making process in resource management and production units is still a poorly studied and nonconformity topic [
2]. As an example, the authors of [
1] studied the American market and pointed out the political changes resulting from the outcome of the elections in the United States as well as their regulations over time as influential factors in the attractiveness of the market, such as the “Bring Jobs Back to America” campaign [
1]. As of 2010, the new American incentives to contain the number of employees in these industries and to reduce external technological dependence influenced the movement of production back to the United States, in addition to local development and increased exports in the country [
9].
Managers also pointed out issues that became more important during a three-year period: supply chain management and objectives related to cost reduction [
1]. To obtain lower costs and more highly profitable results, companies seek the gradual implementation of 4.0 technologies and need for periods of maturity and organizational competence [
7].
This research analyzed 43 papers relating to reshoring and Industry 4.0. It was observed that there was a growth in publications, especially in nine aspects: market uncertainties and labor supply; support for managerial decision making; competitive priorities analysis (costs and efficiency); business strategies; information knowledge and collaboration management; political, social, and economic changes; risk security and privacy management; supply chain management; and investment market and private equity funds.
So far, the main authors who have raised the topic of this research and demonstrated its relevance for future academic studies have been presented. The structure of the text below follows a systematic literature review (SLR) format, and is presented in stages. Finally, a content analysis of the main articles is summarized and conclusions were drawn, considering suggestions for future research.
3. Results and Discussion
Through a content analysis of the selected articles, five types of classifications were made: context of the objective or strand, type of strategy related to location, type of strategy or decision related to the use of technology, integration factors between strategies, and scope level of the research. In addition, the articles were classified according to methodology, approach, country of operation, and internal areas of the study field.
Focusing on the research objective and research question is of paramount importance in judging the quality of the study in administration, as suggested by [
14]. The quality of the study was judged according to its contribution to managerial decision making at the organizational, supply chain, and global levels, which involve the political, economic, and market contexts. A quality study covers and accompanies the new revolution and its development for the purpose of decision making in each context of transformation and globalization.
The research does not cover all of the possible contexts and factors, technologies, and strategies; thus, this is a field of study to be further explored in the literature. Thus, the strategy used was related to location (in English and related to the keywords of reshoring, offshoring, outsourcing, and insourcing); which technology was adopted or developed (related to the keywords of big data, cloud computing, internet of things, and other technologies (4.0)); and what the studies’ contexts were (organizational, supply chain, or global changes).
The articles were also analyzed for objectives or aspects, approaches (quantitative or qualitative), and methodologies (theoretical articles, surveys, case studies, among others). At the end of the classification, six more articles considered to be technical were discarded, as this was not identified using the second criterion, resulting in 37 articles for discussion, as shown in
Table 4.
The articles’ publication newspapers were diversified, with only the first three newspapers having two publications in the areas of the Journal of World Business, Computer law and Security Review, and IEEE Engineering Management Review, as shown in
Figure 4.
There was an increase in articles involving the themes during the last 3 years of the analyzed period. In the years 2010, 2011, and 2015, no articles were found, as shown in
Figure 5. The growth pattern suggests a recent theme, for which the impacts of new technologies and global changes affect organizational strategies. Relevance for management draws the attention of researchers. Most of the articles analyzed companies or professionals from the European continent: 12 articles, 4 of which studied Europe together with America, which leaves 2 articles that exclusively addressed the European continent. Asia was the subject of 8 articles and Oceania 1 article. The other presented articles involved emerging countries (1 survey) or did not present any location specifically (13 articles).
The content analysis was carried out by dividing the articles based on a study of the content, and then they were grouped into global changes, changes in the supply chain, and changes in organizations. The analysis was also conducted with the factors of integration and collaboration between technologies and decision making of organizations, which were found in the classic articles and adapted to the priority subjects of the articles. These were support for managerial decision making; analysis of competitive priorities (cost and efficiency); business strategies; information management knowledge, and collaboration; political, social, and economic changes; risk management; security and privacy; supply chain management; and investment markets and private equity funds.
Figure 6 shows the number of articles in each category.
The review found articles that converged in terms of some main aspects, these being, in decreasing order of the number of articles: market uncertainties and labor supply; support for managerial decision making; competitive priorities analysis (costs and efficiency); business strategies; information knowledge and collaboration management; political, social, and economic changes; risk security and privacy management; supply chain management; and investment market and private equity funds.
The strategies analyzed in the articles are shown in
Table 5 and
Table 6 and refer to the main topics addressed within each subject, or, in other words, the main strategy studied by each revised survey regarding the location-related decision making and specific technologies used for this purpose. As for the production property strategies, only three articles dealt with both subjects—offshoring and outsourcing—while most of the articles dealt with make-or-buy decisions. It is possible to see the relevance of the reshoring movement, as it represented almost a fifth of the articles on location strategies in the context of the new industry. Regarding the strategies for using technologies, most addressed the adoption of new technologies, without specifying or focusing on a specific technology.
The scope of the research reveals studies with organizational scopes, that is, investigating ways to gradually adopt new technologies and assessing the decision-making regarding organizational resources, while global changes have also had significant importance for academic studies, as shown in
Table 7. Regarding the methodologies of the articles, was found a distribution of more qualitative approaches, while the literature presented more empirical (22 articles) than theoretical (15 articles) research. The main areas of activity of the field studies were information technology (four articles) and managers and decision makers (two articles), as shown in
Table 8.
4. Discussion and Implication
The literature focusing on global supply chains and facility locations raises discussion about several concepts and situations related to different types of reshoring processes (e.g., [
1]). Studies involving decision-making regarding resources and organizational units are closely related to the field of supply chain management [
3]. Finally, location decisions and even resource allocations have a close relationship with inventory and production issues [
3]. The dispersion distance is aggravated by the management of multiple locations in multinational companies [
4]. The theoretical concepts related to the reshoring processes demonstrate the challenges, such as the tendency for costs to be increased; therefore, despite its importance in the global context, the topic is still poorly studied [
1,
2].
This paper provides an analysis of the regional and global scenario of the reshoring concept. The bibliographic database revealed that the studies on organizational capacity in terms of technology essentially aimed to provide better strategies regarding the allocation of large amounts of resources and investments in structures and competences. Another relevant finding revealed that the reshoring movement also represents the management of intellectual, technological, and material property through outsourcing decisions and returning to production, which also require major changes in business and in the movement of resources.
The literature trend is moving towards a research agenda that deals not only with the technical and functional approaches to technology, but also with the organizational level and the impacts and relationships between technology and managerial decision making. While the reshoring movement is studied in greater depth in the context of Industry 4.0, new technologies become useful tools to be developed in monitoring, both practically and theoretically, of managerial support for decision making regarding structural and procedural changes.
5. Conclusions, Limitations, and Future Research Avenues
The present research involved a systematic literature review on the relocation movement, specifically focusing on reshoring and Industry 4.0. For this purpose, 43 articles were studied, and as a result, a growth in publications was observed, particularly regarding nine aspects: market uncertainties and labor supply; support for managerial decision making; competitive priorities analysis (costs and efficiency); business strategies; information knowledge and collaboration management; political, social and economic changes; risk security and privacy management; supply chain management; and investment market and private equity funds.
Location strategies, in terms of the reshoring movement and other strategies addressed herein, and Industry 4.0 are recent and relevant topics for the global and managerial context, which includes supply chains and organizations. Despite not being the focus of the studies, the supply chain has a relationship with decision making regarding the location and adoption of new technologies (4.0) because of the need for structural changes, allocation of and investment in resources, and a redesign of the entire production chain and its processes. The main authors of each study also cited the supply chain. It is suggested that researchers delve deeper into supply chain management in order to understand both issues, either jointly or in isolation.
Studies in this area are recent and growing, requiring further research on the theme of theoretical construction and future, more ground-based research. The growth in the number of articles shows the development of both of these topics separately, which are recent in the literature, and of the themes together, which reveals the problems regarding the context: uncertainties regarding the market, competitiveness, changes in the labor supply, and changes in policies. Studies on global, national, and regional scenarios are necessary in order to understand new organizational strategies.
