摘要
进口贸易是国际技术扩散的重要渠道。本文以广东省为例,通过一个扩展的LP模型和协整分析方法研究了省内研发投入和进口贸易对全要素生产率的影响。结果发现,在不考虑人力资本变量时,进口贸易对全要素生产率的提高没有任何贡献;而在考虑到人力资本的动态吸收能力时,进口贸易则对全要素生产率具有正向的促进作用,但其作用随着进口技术系数的提高而缓慢下降。
Importing is one of the most important channels for international technology spillovers.This paper presents the impact of import trade and the R&D on the total factor productivity rate with the data of Guangdong province by the augmented LP model and cointegration test.Our empirical research demonstrates that import-related international technology spillovers have no contribution to the progress of total factor productivity rate without taking account of human capital;However,if taking the human capital into account,the impact is positive and significant,and weakens slowly with the increase of import goods'technology level.
