环境规制、技术创新与产业结构优化升级——基于长三角地区的实证分析

Environmental Regulation,Technological Innovation and Optimization and Upgrading of Industrial Structure——Bases on the Yangtze River Delta

经济可持续发展面临的环境约束日渐明显,环境规制对地区产业结构变化的影响日益显著。采用2011—2020年长三角地区41个城市面板数据,构建固定效应模型、中介效应模型、门槛回归模型,以技术创新为中介变量和门槛变量,探究环境规制对产业结构优化升级的影响机制。环境规制促进长三角产业结构优化升级,其对普通城市产业结构优化升级的促进作用大于核心城市;技术创新在环境规制促进产业结构优化升级的路径中起到部分中介作用;门槛效应分析发现技术创新水平的提高,会促进第二产业发展,限制环境规制促进产业结构优化升级。建议因地制宜、灵活实施环境规制,强化技术创新的中介作用,加快推动长三角产业结构优化升级。

By analyzing the data from 41 cities in Yangtze River Delta from 2011 to 2020,it is found that environmental regulation can promote the optimization and upgrading of industrial structure,and its effect is much more obvious in ordinary cities than in the core cities.Technological innovation plays an intermediary role in the process,and can also promote the development of the secondary industry,as well as restricting environmental regulation's effect to some content.Therefore,it is suggested to implement flexible environmental regulation accordingly,strengthen technological innovation to accelerate the optimization and upgrading.
