Corporate Network, Co-patenting, and Technological Innovation

木村遥介(東京工業大学)

This paper conducts an empirical investigation into the interplay among corporate networks, co-patenting activities, and technological innovation among Japanese listed companies. By constructing a dataset that integrates corporate shareholdings, customer relationships, and patent data, we analyze the extent to which inter-firm relationships foster collaborative innovation, as proxied by co-patenting practices. Our findings indicate that closer inter-firm proximities enhance the propensity for collaboration, effectively reducing the barriers posed by geographical and technological distances. Additionally, we assess the value of co-patenting through both citation-based and market-based measures of innovation, providing a multifaceted view of its impact on technological advancement.
