Impacts and channels of knowledge spillover from universities and local public technology centers in regional innovation systems

日本经济自上世纪90年代以来一直处于长期低迷状态。在这种情况下，成功地将公共资助的研究成果转移到私营部门进行商业化，从而促进工业创新，从而提高国民生活水平变得非常重要。本研究基于企业的专利、大学研究、地方政府管理的地方公共技术中心的技术转让活动等面板数据，对日本的公共研究向民间R&D溢出的情况进行了定量评价。讨论了实证结果的若干理论和政策含义。

Japan has been suffering from the long-term sluggish economy since 1990s. Under such circumstances, it has become important to successfully transfer the outcome of publicly-funded research to the private sector for commercialization, which promotes industrial innovations and consequently, improves the national living standard. Based on panel data of firms' patents, university research, and technology transfer activities of local public technology centers administrated by the local authorities, this study quantitatively evaluated how publicly-funded research in Japan spilled over into private R&D. Several theoretical and policy implications from empirical results were discussed.
