对外直接投资与中国工业绿色全要素生产率——基于环境规制与吸收能力视角分析

OFDI and the China’s Industrial Green Total Factor Productivity Based on the Perspective of Environmental Regulation and Absorptive Capacity

基于中国30个省份的面板数据,采用交互模型探讨OFDI对中国工业全要素生产率的影响,并进一步构建门槛模型考察区域吸收能力如何影响OFDI与绿色全要素生产率(GTFP)之间的关系。研究发现:从全国层面看,OFDI显著提升了绿色全要素生产率,环境规制正向调节二者之间关系;从分样本看,OFDI显著提升了东部地区的绿色全要素生产率,环境规制正向调节两者之间的关系,而对中西部地区的影响不显著;运用面板门槛检验环境规制、金融发展和人力资本在OFDI对GTFP影响中的非线性门槛效应,检验显示环境规制水平、金融发展水平和人力资本水平均存在显著的单门槛效应。

Based on the panel data of 30 provinces in China,this paper uses the channel model to investigate the relationship between OFDI and China’s industrial green total factor productivity.Furthermore,this paper uses threshold model to explore how the regional absorptive capacity can influence the relationship between them.The results show as follows,on the whole,OFDI has a significant positive effect on GTFP,and environmental regulation positively regulates the effect of OFDI on GTFP.From the sample results,OFDI has a significant positive impact on GTFP in eastern region,and environmental regulation positively regulates the relationship between the two,but has no significant impact on central and western region.On this basis,environmental regulation,financial development and human capital are used as threshold variables to test the threshold effect.The test shows that OFDI reverse technology spillover is limited by the level of environmental regulation,financial development and human capital,and there is a single threshold effect.
