FDI质量对区域经济高质量发展影响的门槛效应研究

An Empirical Research on the Threshold Effect of FDI Quality on High-Quality Growth of Regional Economy

外商直接投资(FDI)是推动经济增长的重要因素之一,其质量对我国经济高质量发展有着至关重要的作用。以2006—2019年我国省级面板数据为样本,采用Index DEA模型构建经济高质量发展指标体系,以技术进步作为门槛变量,运用面板门槛模型检验FDI质量对经济高质量发展的影响效应。研究发现:FDI质量对经济高质量发展存在非线性门槛效应;随着技术进步的提升,FDI质量对经济高质量发展的影响逐渐增强;对于全国和东西部地区,FDI质量对经济高质量发展存在双门槛效应,对中部地区存在单门槛效应。研究结论表明,各区域应在提高技术水平的基础上,合理引进高质量外商直接投资,实现经济高质量发展。

Foreign direct investment(FDI) is one of the important factors to promote China’s economic growth, whose quality plays a crucial role in China’s high-quality economic growth. Taking the provincial panel data in China from 2006 to 2019 as samples, this paper adopts the Index DEA model to construct an index system for high-quality economic grwoth. Then it takes technological progress as the threshold variable and uses the panel threshold model to analyze the effect of FDI quality on high-quality economic growth. It is found that FDI quality has a nonlinear threshold effect on high-quality economic growth. With the improvement of technological progress, the effect of FDI quality on high-quality economic growth increases successively. For the whole country, eastern and western regions, FDI quality has a double threshold effect on high-quality economic growth, and a single threshold effect on that in the central region. The research shows that it is reasonable for each region, on the basis of improving the technical level, to introduce high-quality FDI in order to realize high-quality economic growth.
