摘要
本文在前人研究的基础上,进一步探讨进口贸易的技术溢出效应,在进口贸易的外溢模型中引入实际进口渗透率变量,构建一个以全要素生产率为被解释变量,以国(省)内研发投入和进口来源国研发投入为解释变量的回归方程,并尝试引入一个反映进口贸易政策环境变化的虚拟变量,对进口贸易的技术外溢效应进行测度。本文通过采用广东省的相关数据进行实证分析,表明了进口贸易对广东省的技术进步有显著的促进作用。
The paper does further research on technology spillovers effect through imports,and introduces a factor of actual imports penetration rate in the measuring model of technology spillovers.Construct a regresion equation,using total factor productivity as dependent variable,R&D input of a country(province)and R&D input of import source countries as variables.In the regresion equation we attempt to indicate a dummy variable which reflects the change of import trade policy and inviroment,then explores the extent to tehnology diffusion through imports.The empirical study of Guangdong province shows that the advanced technology and R&D achievement of trade partners significantly promote the technology progress through imports.
