长江经济带作为我国发展格局中的重要战略组成部分,正面临环境保护与产业结构升级的问题,环境规制的实施能否有效促进产业升级?本文利用长江经济带2000—2014年30个主要城市的动态面板数据,实证分析环境规制对产业升级的影响,结果表明:环境规制强度和产业结构升级呈U型关系,当环境规制强度较弱时,会抑制产业升级,当环境规制强度越过门槛值且不断增强时,产业结构水平持续上升;长江经济带总体环境规制强度较低,主要城市依然处于外延式的发展阶段;长江经济带发达城市的拐点值小于欠发达城市,相对更容易越过门槛值进而使得环境规制促进产业结构升级。
As an important strategic part of China’s development pattern, the Yangtze River Economic Belt is facing the issue of environmental protection and upgrading of industrial structure. Can the implementation of environmental regulation effectively promote industrial upgrading? This paper uses the Yangtze River economic belt in 30 major cities of 2000-2014 Dynamic panel data to empirically analyze the impact of environmental regulation on industrial upgrading. The results show that the intensity of environmental regulation and the upgrading of industrial structure show a U-shaped relationship. When the intensity of environmental regulation is weak, it will restrain industrial upgrading. When the intensity of environmental regulation crosses the threshold The level of industrial structure continued to rise; the overall intensity of the environmental regulation in the Yangtze River Economic Belt was relatively low; the major cities were still in an extended phase of development; the inflection point of developed cities in the Yangtze River economic belt was less than that of less developed cities and was relatively easy to cross the threshold Making environmental regulation to promote the upgrading of industrial structure.
