对外直接投资逆向技术溢出对中国技术创新的影响研究——基于长江经济带的门槛面板模型分析

Research on the Influence of OFDI Reverse Technology Spillover on China's Technological Innovation——Based on the analysis of the threshold panel model of the Yangtze River Economic Belt

本文基于2006—2018年长江经济带的省际面板数据,在利用基准回归模型检验OFDI逆向技术溢出对技术创新促进作用的基础上,构建了门槛面板模型,检验不同经济开放度下OFDI逆向技术溢出对我国技术创新的影响。实证结果表明,衡量经济开放度的三个指标中,研发强度和技术差距均存在单一门槛作用,并且对OFDI逆向技术溢出起到明显地促进作用;而市场开放度则存在双重门槛,呈现出先促进再阻碍而后又促进的过程。最后,结合长江经济带地区的发展实际,提出了利用OFDI促进技术创新的措施建议,以期为我国经济高质量发展提供参考。

Based on the provincial panel data of Yangtze River Economic Zone from 2006 to 2018,this paper constructs a threshold panel model to test the impact of OFDI reverse technology spillover on technological innovation in China under different degrees of economic openness,based on the use of a benchmark regression model to test the role of OFDI reverse technology spillover on technological innovation promotion.The empirical results show that among the three indicators measuring economic openness,both R&D intensity and technology gap have a single threshold effect and contribute significantly to OFDI reverse technology spillover.While the market openness has a double threshold,showing a process of promoting and then hindering and then promoting again.The paper concludes with suggestions on measures to use OFDI to promote technological innovation in the light of the actual development of the Yangtze River Economic Zone region,with a view to providing references for the high-quality development of China's economy.
