Absorptive capacity for science-based innovation propensity: an empirical analysis using Japanese National Innovation Survey
利用日本国家创新调查数据，结合学术论文和专利信息，分析企业实现基于科学的激进创新所需的吸收能力类型，发现内部研发和具有大学科研经验的人力资本对通过大学合作实现创新至关重要。
Abstract It is found that private firms are withdrawing from basic research, as evidenced by the decline in the number of scientific papers written by authors who are inside of firms. On the other hand, scientific knowledge is becoming increasingly important in the industrial innovation process, so that accessing external scientific knowledge for science based innovation becomes critical to radical innovation at firm. This study conducts an empirical analysis of absorptive capacity required to realize radical innovations based on scientific knowledge. Specifically, by connecting bibliographic information of academic papers and patents with firm data from the Japanese National Innovation Survey, we analyze the type of absorptive capacity by the way to obtain external knowledge. The results show that internal R&D is important both for with and without collaboration with university, while human capital with experiences of scientific research in university is important, particularly for successful innovation through university collaboration.
