摘要： 偏向性技术进步是影响收入分配和经济增长的关键变量,构建了基于开放贸易框架下的知识产权保护和偏向性技术进步理论模型,采用标准供给面系统方法测度了我国各省份的偏向性技术进步程度,并结合我国2003—2020年省级面板数据实证分析了知识产权保护对偏向性技术进步的影响,丰富了偏向性技术进步的相关研究。结果表明:(1)知识产权保护水平提升会促使我国技术进步偏向资本。在采用工具变量法、替换解释变量、Probit面板估计以及采用PSM-DID估计后,结果依旧稳健。(2)知识产权保护对偏向性技术进步的影响存在异质性,知识产权保护对偏向性技术进步的影响效应在中、西部省份和知识产权保护弱省中更强。(3)从影响机制来看,国际贸易是知识产权保护影响资本偏向性技术进步的重要渠道,其中进口贸易起正向促进作用,出口贸易则发挥了负向抑制作用。

Abstract: Biasing on technological change that is a key variable affecting income distribution and economic growth, this paper constructs a theoretical model of intellectual property protection and technological progress bias under the framework of open trade, and then uses the normalized supply side system method to measure the technology progress bias of China's provinces. Combined with the data of 30 provinces in China from 2000 to 2017, this paper empirically analyzes the impact of intellectual property protection on technological progress bias, enriching the research of bias technical change.The results show that:(1) The improvement of intellectual property protection level can promote China's technological progress in favor of capital. The results are still robust with the instrument variable method, alternative explanatory variables, Probit panel estimation and PSM-DID estimation. (2) The impact of intellectual property protection on technological progress bias is heterogeneous. The impact of intellectual property protection on technological progress bias is stronger in provinces which are located in the central, western or with relatively low level of intellectual property rights. (3) From the perspective of impact mechanism, international trade is an important channel for intellectual property protection to influence technological progress bias, in which import trade plays a positive role, while export trade plays a negative inhibitory role.

Key words: intellectual property protection, international trade, technological progress bias
