知识产权保护的区域技术创新效应与技术获取渠道异质性研究

The Technological Innovation Effect of Intellectual Property Rights Protection and the Heterogeneity of Technology Access

构建了"知识驱动型"两部门模型,利用2005-2012年中国内地24个省市面板数据,借助"杰菲"知识生产函数构建了动态面板模型,从理论与实证角度探讨了知识产权保护对于区域技术进步的作用机理。对区域技术知识的来源渠道进行了细分,改进了现有技术知识存量的测算方法,对知识产权保护指数进行了区域化处理,使之更加契合各地区真实情况。实证结果显示:自主创新是我国区域技术进步的主要动力,国内技术引进与国外技术引进产生的技术进步效益存在显著差异;知识产权保护与区域技术进步之间存在倒U型关系,各地区要根据自身资源禀赋差异,合理调整知识产权保护强度,并制定科学的技术引进战略。

Firstly,this paper builds the knowledge-drive two sector model,then collects the China panel data of 24 provinces during the period of 2005-2012,and establishes the dynamic panel data model based on the Jaffe A.B production function in order to probe into the impact of IPR on regional technological progress from a theoretical and empirical perspective in turn.The main contributions of this study are listed as follows：this paper subdivides the sources of regional stock of technological knowledge,improve the calculation method of the existing stock of technological knowledge,and processes the IPR index towards regionalization so as to make it closer to different regional situations.The empirical results show us two points：independent innovation is the major driving force of Chinese regional technological progress at the present stage,and there are significant differences on benefits of technological progress between domestic and foreign technology introduction;there exists an inverted ＂ U＂ relationship between IPR protection and regional technological progress.All regions should adjust the protective intensity of IPR according to their own resource endowment,and develop scientific strategies on technology introduction.
