Collaborative knowledge creation: Evidence from Japanese patent data

Mori, Tomoya and Sakaguchi, Shosei (2018): Collaborative knowledge creation: Evidence from Japanese patent data.

Abstract

This paper presents micro-econometric evidence for collaborative knowledge creation at the level of individual researchers. The key determinant for developing new ideas is the exchange of di�erentiated knowledge among collaborators. To stay creative, inventors seek opportunities to shift their technological expertise to unexplored niches by utilizing the di�erentiated knowledge of new collaborators. Moreover, the knowledge stock of an inventor, proxied by the scope of an inven- tor 's past research, has positive and negative e�ects on their productivity. This is because it facilitates successful collaboration; however, simultaneously, the dependence on older knowledge hinders invention possibly due to the obsolescence and exhaustion of niches by imitation.
