外国直接投资对我国制造业技术溢出的渠道研究

外国直接投资(FDI)对内资企业的技术溢出有不同的渠道效应。本文首先利用Malmquist指数方法测算出了我国制造业全要素生产率(TFP),并将TFP分解成技术进步指标与技术效率指标,利用脉冲响应函数和Geweke分解检验分别动态模拟了FDI对技术进步与技术效率两种渠道的影响程度,以及FDI与两者的因果关系。研究表明:FDI对制造业生产率的溢出机制主要是通过对技术效率的提升表现出来的,但对技术进步的促进作用不明显。

Study on the Double Channels of Technical Spillover from FDI to Manufacturing Industry in China

There are different technique spillover channels from foreign direct investment. Based on a nonparametric Malmquist index approach, this paper analyzes the total factor productivity trend in China's manufacturing industry, which is decomposed into technical efficiency and technical progress. Impulse response model and Geweke method is used to dynamically simulate the effect on technical efficiency and technical progress from FDI and causality between the variables. The results indicate that: manufacturing industry productivity spillover from FDI is mainly due to the advance of technical efficiency, there is no strong relationship between FDI and technical progress.
