OFDI与国内创新能力关系中的“门限效应”:区域金融发展视角的实证分析

Threshold effect between OFDI and innovation ability: An empirical analysis based on financial development

采用2003-2011年中国省际面板数据,以区域金融发展为门限变量,构建非线性面板门限回归模型,实证考察了OFDI与国内区域创新能力关系中的"门限效应"。研究结果表明:我国各地区OFDI对国内区域创新能力的影响存在显著的金融发展门限效应:当金融发展低于门限值时,OFDI对国内创新能力不存在显著的影响;而当金融发展高于门限值时,OFDI对国内创新能力具有显著的促进效应。研究还发现,总体上我国各地区金融发展处于相对较低水平,OFDI对国内区域创新能力不存在显著影响;只有北京、上海和浙江等地区的金融发展处于较高水平,在推进OFDI时会提升其创新能力。

A nonlinear panel threshold regression model is constructed based on Chinese panel dated between 2003 and 2011 from 30 provinces to analysis the impact of OFDI on regional innovation capability and its financial development 'threshold effect'. The results show that there is significant financial development threshold effect on the innovation ability in China from OFDI: the OFDI has no significant effect on the innovation ability,when financial development is lower than the threshold value;the OFDI has significant positive effect on the innovation ability,when financial development is higher than the threshold value.The results also show that Beijing,Shanghai and Zhejiang are in high financial development area while most of the remaining area are in lower level of financial development.
