环境规制、FDI对绿色全要素生产率的影响

The Influence of Environmental Regulation and FDI on Green Total Factor Productivity

文章结合SBM-DDF模型和Malmquist-Luenberger (ML)指数测算我国30个省份2005~2019年的绿色全要素生产率(GTFP),并运用系统GMM方法和面板门槛模型深入探讨了环境规制、FDI及二者协同作用对我国GTFP的影响。研究结果表明:第一,环境规制促进了我国GTFP提高,FDI及二者交互项抑制了我国GTFP提高;第二,环境规制对全国和内陆地区GTFP的促进作用存在FDI门槛效应,分别具有边际效率递减和边际效率递增的非线性规律。

Combined with SBM-DDF model and Malmquist-Luenberger (ML) index, this paper calculates the green total factor productivity (GTFP) of 30 provinces in China from 2005 to 2019, and uses System GMM method and the panel threshold model to discuss the impact of environmental regulation, FDI and their synergism on GTFP in China. The results show that: first, environmental regulation promotes the improvement of GTFP in China, while FDI and their interaction inhibit the improvement of GTFP in China;second, there is an FDI threshold effect in the promotion of GTFP in the whole country and inland areas, which has the non-linear law of decreasing marginal efficiency and increasing marginal efficiency, respectively.
