知识产权保护与国际R&D溢出

Intellectual Property Rights Protection and International R&D Spillovers

国际贸易和外商直接投资(FDI)是国际R&D溢出的两个重要渠道,而知识产权保护是影响国际贸易和FDI技术溢出效应的重要因素。据此,本文运用中国1985～2008年的经济数据实证考察了知识产权保护、国际R&D溢出对中国技术进步的影响。分析结论显示:(1)进口贸易和外商直接投资R&D溢出渠道均能显著促进中国的技术进步,外商直接投资R&D溢出渠道是中国提升技术水平的重要途径;(2)知识产权保护的直接效应不利于中国的技术进步;(3)知识产权保护与国内研发的协同效应显著促进了中国的技术进步,知识产权保护与进口贸易和FDI溢出渠道的协同效应对中国技术进步的影响显著为正。

International trade and foreign direct investment are two important channels that show international R&D technology spillovers.Intellectual property rights protection is one of the important factors which determine international technology spillovers through the import trade and FDI channel.So this paper investigates the effect of intellectual property rights protection and international R&D spillovers on technology progress in China using the data from 1985 to 2008 in China.The results show that:(1) International technology spillovers through the import trade and FDI channel can significantly promote technology progress in China.(2) The direct effect of intellectual property rights protection on technology progress is not obvious.(3) The cooperative effect of intellectual property rights protection and domestic R&D on technology progress is significantly positive,the cooperative effect of intellectual property rights protection and international R&D technology spillovers through the import and FDI channel on technology progress is significantly positive.
