我国OFDI逆向技术溢出效应的研究——基于省际面板数据的门槛回归分析

利用2003—2013年我国29个省级行政区的省际面板数据实证分析我国对外直接投资(OFDI)的逆向技术溢出效应,结果显示,我国OFDI存在逆向技术溢出效应,且这种效应存在显著的地区差异性。门槛模型的回归结果表明,我国OFDI的逆向技术溢出效应不受经济自由度的影响,但受创新能力和金融发展水平的制约,创新能力和金融发展水平均存在门槛效应,当其跨越门槛值时,OFDI的逆向技术溢出效应显著增加。

A Study on the Reverse Technology Spillovers from China's OFDI-Based on the Threshold Regression Analysis of Inter -provincial Panel Data

This paper examines the reverse technology spillovers from OFDI based on China's inter -provincial panel data from 2003—2013.The empirical results show that the reverse technology spillovers from China's OFDI really exists,but there is a significant difference among regions of China.The results of threshold regression model show that economic free-dom has no effect on the reverse technology spillover effect of OFDI,while innovation capacity and financial development level have threshold effect on the reverse technology spillover effect;the effect increases significantly when innovation ca-pacity and financial development level exceeds the threshold.
