环境规制强度、产业结构升级与生态环境优化的互动机制分析

实现产业结构升级与生态环境优化二者间的良性互动,对促进中国经济由高速增长阶段向高质量发展阶段转化至关重要。基于我国30个省份2003-2016年环境规制、产业结构与生态环境的面板数据,应用三阶段最小二乘法,实证检验环境规制强度、产业结构升级与生态环境优化三者之间的互动机制。研究发现：在全国层面,产业结构升级在促进生态环境优化的同时,弱化了环境规制强度;环境规制具有"倒逼"机制,在促进我国产业结构升级的同时,也能促进生态环境优化;分区域看,产业结构升级均有利于区域生态环境优化,但受资源禀赋等异质性因素的影响,环境规制强度、产业结构升级与生态环境优化之间的互动机制存在差异。发挥环境规制的功能性作用,落实创新驱动发展战略,推动区域协调发展,是实现产业结构升级与生态环境优化的可行性路径。

Analysis of Interactive Mechanism of Environmental Regulation Strength,Industrial Structure Upgrading and Ecological Environment Optimization

The benign interaction between industrial structure upgrading and ecological environment optimization is crucial to promote the transformation of China's economy from high-speed growth stage to high-quality development stage. Based on the panel data of environmental regulation, industrial structure and ecological environment in 30 provinces of China from 2003 to 2016, this paper applies the three-stage least squares method to empirically test the interaction mechanism between environmental regulation intensity, industrial structure upgrading and ecological environment optimization. The study found that at the national level, the upgrading of industrial structure has weakened the intensity of environmental regulation while promoting the optimization of ecological environment; environmental regulation has a "forced-down" mechanism, which can promote the optimization of ecological structure while promoting the upgrading of China's industrial structure; In terms of regions, the upgrading of industrial structure is conducive to the optimization of regional ecological environment. However, due to the heterogeneity factors such as resource sharing, the interaction mechanism between environmental regulation intensity, industrial structure upgrading and ecological environment optimization is different. It is a feasible path to realize the upgrading of industrial structure and the optimization of ecological environment by exerting the functional role of environmental regulation, implementing the innovation-driven development strategy, and promoting regional coordinated development.
