中国TSFDI逆向技术溢出对国内技术水平提升影响程度研究——基于溢出机制和影响因素的视角

Influence of China's TSFDI Reverse Technology Spillover on Domestic Technological Upgrading:From the Perspective of Spillover Mechanism and Influence Factors

技术获取型对外直接投资(TSFDI)是一国利用技术外溢效应来实现本国技术进步的有效路径,在推进我国现阶段经济转型和结构调整方面扮演着重要角色。为此文章以1985~2015年技术获取型对外直接投资数据甄别为基础研究了我国技术获取型对外直接投资逆向技术溢出的影响程度、作用机制和影响因素。结果显示,我国技术获取型对外直接投资会产生显著的逆向技术溢出效应,即技术获取型对外直接投资每增加1%将引致国内全要素生产率增长0.0086%,效应程度不及国内研发和进口贸易;此外,逆向技术溢出效应还受到人力资本水平和技术差距等因素影响。

TSFDI is an effective path for of a country to use technology spillover effect for realizing technology progress,and it plays an important role in promoting China's economic transformation and structural adjustment. Therefore this paper analyzes the influence degree、mechanism and influence factors of TSFDI' s reverse technology spillover on the base of TSFDI data screening between1985 and 2015. The results show that China's TSFDI can produce reverse technology spillover effect significantly. 1% TSFDI increase will improve TFP by 0. 0086%,and the effect degree is less than domestic R&D and import. In addition,the reverse technology spillover effect is also affected by human capital level and technology gap etc.
