As a result of an increasing amount of research literature available in the field of coopetition (Bengtsson et al., 2016, p. 4), the primary intention to craft this Masters Thesis is to provide meaningful data to the interested reader. The scientific work is intended as traditional literature review, which means that it is a theoretical desk research. The term coopetition was initially established in the 1980s and was then brought to conventional business in the 1990s by the researchers Brandenburger and Nalebuff (1996). Coopetition is a blend of cooperation and competition, which is simultaneously applied in business practice among competitors. In traditional business view, both concepts are perceived as opposing entities (Chen, 2008). However, this perspective has been changed since the uprising of the overall concept of coopetition. From a normative standpoint, coopetition helps firms to achieve superior performance and this Masters Thesis is summing up current research findings with this regard. According to current research, the concept of coopetition is segmented into the intra-, inter- and network-level of coopetition, wherein the inter-firm and network level is subject to extensive research (Dahl et al., 2016). In the first place, simultaneous cooperation and competition have been researched from distinctive theoretical standpoints. The most common underlying theories, which have been applied to coopetition are, for instance, the game theory, the resource-based view, the network approach, the transaction cost economics and the resource dependence theory (Bengtsson & Kock, 2014, p. 180). The Masters Thesis includes theoretical approaches to investigate the antecedents, behaviors and potential outcomes for firms engaged in coopetitive relationships. Furthermore, a multilevel model is included to advance coopetition research by taking into account actors and activities as units of analysis. The actors and activities are then integrated and analyzed along with its drivers, processes, and outcomes (Bengtsson & Raza-Ullah, 2016, p. 33). The provided theoretical background allows for the investigation of coopetition in globalized and dynamic business environments. In order to deal with global coopetitive relationships, multinational corporations (MNC) and global alliances are provided with applicable situational recommendations which have been developed by Luo (2007). The situational recommendations considering the intensity and diversity of global coopetition. The intensity of coopetition refers to the degree of competition and cooperation, while the diversity of coopetition covers the geographical breadth and number of engaged coopetitive relationships. This Masters Thesis further states mechanisms for the management of tensions as well as current findings from the coopetition strategy realm, which is contemporarily researched from the strategy-as-practice perspective (Dahl et al., 2016; Lundgren-Henriksson & Kock, 2016a). With regard to the management of tensions, it is argued that cooperating competitors either have to separate or integrate identified critical activities and resources to ensure effective management (Fernandez et al., 2014; Seran et al., 2016). The key aspect of this scientific work is an investigation of the implications of coopetition on competitiveness. In order to categorize empirical research papers related to competitiveness implications of coopetition, Bengtsson and Raza-Ullahs (2016) classification has been applied. The researchers distinguish outcomes of coopetition into knowledge, innovation and firm performance. According to current research results, it is still not clear whether or not coopetition increases competitiveness. However, several research studies supporting the hypothesis that coopetitive arrangements have positive effects on competitiveness in terms of knowledge, innovation and firm performance. For example, the researchers Kumar and Dutta (2017), Huang and Yu (2011) and Kostopoulos et al. (2011) have revealed that coopetition has positive effects on competitiveness, whereas quantitative research studies from Kang and Kang (2010) and Nieto and Santamaria (2007) have identified otherwise. As a result, there are still more empirical research efforts required to answer that research issue.
