Technology that develops rapidly has profoundly affected the business field and reshaped some behaviours of corporations, and the discussion on startup risk-taking behaviour in the new era is still insufficient. Based on social network theory and social capital theory, this article studies how social networks and entrepreneurial ecosystems support startup risk-taking behaviour. This article cuts into this issue through the perspective of coopetition. Based on 737 responses, this article employs regression and fuzzy-set qualitative comparative analysis to explore the relationships between networks, ecosystem coopetition, and risk-taking behaviour. Results indicate that networks and coopetition may stimulate startup risk-taking behaviour, and coopetition may weaken the impacts of networks. There are replacement effects between different characteristics of networks, and there are several configurations, which may lead to high-level risk-taking. This article may help us understand startup risk-taking behaviour in the digital era and the positive impacts of ecosystems.

Firms that are located in a cluster may confront cooperation and competition at the same time. The advantage of cooperation and the disadvantage of competition on a firm may need to examine the firm survival in a cluster as the cluster evolves. Employing the population ecology viewpoint, this study tries to address coopetition issues in a cluster to examine the impact of coopetition on firm survival rate. Analyzing yacht industry data in Taiwan from 1957–2010, this study indicates that the founding rate of yacht firms will be positively related with the cluster size. Additionally, during the competition period, those firms located inside the cluster may have a higher dissolution rate than those firms outside the cluster, indicating the disadvantage of competition on the firm. Finally, this study finds that those firms located inside the cluster will be more likely to become larger and have capabilities to survive. The results in this study provide insights on addressing coopetition issues in a cluster.

From a coopetition perspective, we differentiate between a multinational enterprise's product-similar subsidiary network and product-different subsidiary network in a host country. We argue that the product-similar network will have a curvilinear (inverted U-shaped) effect on foreign subsidiary performance, whereas the product-different network will produce a monotonic (positive) effect. Moreover, we introduce host-country economic advantage and intangible resource of the subsidiary as moderators into the relationship between subsidiary network and performance. Using longitudinal panel data of foreign subsidiaries, we find evidence that when host-country economic advantage is large, and the level of intangible asset intensity is high, the inverted U-shaped effect of product-similar subsidiary network is less pronounced. Moreover, host-country economic advantage and intangible asset intensity both enhance the positive effect of product-different subsidiary network. However, the moderating effect of intangible asset intensity is opposite to our prediction.
