This project examines the effects of exploitation of outside knowledge on the firm's innovation performance. Especially, our focus is on the effects of (i) mobility and diversity of inventors, (ii) collaboration with other organizations and the firm's openness of technological knowledge, and (iii) knowledge exchange through overseas expansion to the Association of Southeast Asian Nations (ASEAN) countries. We also examine the effect of (iv) the Chinese patent system and the preferential treatment system for the high-tech enterprise on the efficiency of the catching-up process of those firms. These analyses will provide some important implications for Japanese innovation policy.
