从环境规制强度内生于外资规模与外资质量的角度切入,在拓展Copeland与Taylor模型的基础上,剖析FDI影响工业环境效率的机制,并构建联立方程模型和面板门槛回归模型,实证检验FDI规模与质量特征影响工业环境效率的机制与效应,研究发现:(1)外资规模通过产业结构渠道抑制了工业环境效率的提升,但外资规模与质量均能通过环保技术与经济发展途径改善工业环境效率;(2)外资特征会直接影响FDI对中国环境规制强度的作用程度甚至方向,FDI规模因其带来的环境压力会引发当地环境规制强度的上升,而FDI质量作为地方政府争夺的潜在资源,倾向于弱化当地的环境规制;(3)FDI质量与规模对工业环境效率的影响均存在显著的双重门槛效应。当环境规制强度较低和较高时,FDI规模对工业环境效率的影响表现为负面,FDI质量对工业环境效率的影响不显著;当环境规制强度适度时,FDI规模对工业环境效率的负面效应减弱,FDI质量对工业环境效率则产生了积极的影响。
Based on the extension of Copeland and Taylor models, this paper analyzes the mechanism of FDI impact on industrial environmental efficiency, and establishes the simultaneous equation model and panel threshold regression model to test FDI from the angle of environmental regulation intensity endogenous to foreign investment scale and foreign investment quality. The results show that: (1) The scale of foreign capital has inhibited the improvement of industrial environmental efficiency through the channels of industrial structure, but both the scale and quality of foreign capital can improve the industrial environment through environmental technology and economic development (2) The characteristics of foreign capital will directly affect the degree and direction of FDI on the intensity of China’s environmental regulation. The scale of FDI will lead to the rise of the intensity of local environmental regulation because of the environmental pressure brought by FDI, and the quality of FDI as a potential resource for local governments to compete for , Tend to weaken the local environmental regulation; (3) Both the quality and the scale of FDI have a significant double threshold effect on the industrial environmental efficiency. When the intensity of environmental regulation is low and high, the impact of FDI scale on industrial environmental efficiency is negative, and the impact of FDI quality on industrial environmental efficiency is insignificant. When the intensity of environmental regulation is moderate, the negative effect of FDI scale on industrial environmental efficiency Weakening, the quality of FDI has had a positive impact on the efficiency of industrial environment.
