This study was built upon Nahapiet and Ghoshal's three dimensions of social capital-structural, relational, and cognitive. It addresses three research questions:(1) Are there significant differences in social capital between nascent entrepreneurs and the general public (control group)? (2) Are there significant differences in social capital between technology and nontechnology nascent entrepreneurs? (3) How do the three dimensions of social capital interact among themselves across different sample groups? These questions were examined by using the Panel Study of Entrepreneurial Dynamics data set. Results suggest that there are no significant differences in various dimensions of social capital between nascent entrepreneurs and the general public. What differentiates the two groups is not the amount of social capital but the patterns of association among its different dimensions. Additionally, the

This study examines the relationship between firm absorptive capacity and organizational responsiveness in the context of growth-oriented small and medium-sized enterprises (SMEs). By testing the different dimensions of absorptive capacity, external knowledge acquisition and intrafirm knowledge dissemination were found to be positively related to organizational responsiveness. In addition, the relationships between absorptive capacity and organizational responsiveness were moderated by environmental dynamism and the SMEs' strategic orientation. Results demonstrate that the responsiveness of growth-oriented SMEs is expected to increase if (1) they have well-developed capabilities in external knowledge acquisition and intrafirm knowledge dissemination; (2) they have a well-developed external knowledge acquisition capability and adopt a more proactive strategy, such as being a prospector; (3) they face a turbulent environment and have a well developed internal knowledge dissemination capability. Implications and future research directions are provided.

This paper extends the dynamic capability perspective into the study of innovation by entrepreneurial firms. Drawing from both the resource-based view and the dynamic capability perspective, this paper explores theoretically and examines empirically the different roles played by a firm's resource stock (endowment of resources and capabilities) and its integrative capabilities (ability to recognize opportunities as well as to configure and deploy resources) in the process of firm innovation. Our structural equation modeling results, based on a sample of 120 Internet-based companies, indicate that both the firm's resource stock and integrative capabilities affect its innovation. Additionally, we also found that the relationship between resource stock and innovation is mediated by integrative capabilities. That is, merely possessing well-endowed resource stock per se is not sufficient for innovation. Thus, it is the firm's ability to mobilize its resources and capabilities and align them dynamically with the changing opportunities in the environment that is of vital importance as the firm constantly innovates to survive and create its own competitive advantage. In the hypercompetitive and fast changing Internet-based environment, such a need for dynamic capabilities is especially accentuated. Implications and suggestions for future research are provided.Jianwen (Jon) Liao is an associate professor of strategy and entrepreneurship in the Stuart

We consider the applicability to digital platforms of extant international business scholarship. The organization of digital platforms has been seen to such an extent as predicated upon the bundling of external resources for collective value creation that their expansion may follow the logic of externalization. We further that literature contrasting the governance of network multinationals with that of platform-centric ecosystems. Building on and extending the theory of the ecosystem, we propose the concept of ecosystem-specific advantages. We identify costs and difficulties in the transfer of such advantages to new markets, emphasizing in particular the idea of bottlenecks. We then propose a framework that can be applied to future research on digital platforms, focusing on the users, suppliers of complementary products, and platform firms. We also call for research on the dynamic process of creating, transferring, and upgrading ecosystem-specific advantages. Journal of International Business Studies (2019).
