Inter-Organizational Network and R&D Activity in Japanese Bio-Ventures

This study examines the factors that contribute to the R&D activity of drug discovery and reagent bioventures in Japan. We mainly focus on the external networks built by these ventures. We target 186 bioventures established from 1995 to 2015 and analyze the networks of their joint patent applications. We find that positions of bridging relationships with other organizations in the network; that is, betweenness centrality is positively correlated to R&D activity. We also analyze how the origins and
attributes of organizations affect the network effect. Furthermore, we find that bio ventures’ IPOs boost
the network effect, while being a universitylaunched venture reduces the network effect.
