环境规制、科技创新协同推进经济高质量发展机理研究——以成渝地区双城经济圈16个城市为例

Study on the mechanism of synergistic promotion of high-quality economic development by environmental regulation and scientific and technological environmental regulation,technological innovation and high-quality economic development——A case study of 16 prefecture-level cities in Chengdu-Chongqing Economic Circle

环境规制与科技创新是区域经济高质量发展的重要驱动力,以2014-2020年成渝地区双城经济圈16个城市的面板数据,基于新发展理念构建了经济高质量发展评价体系,运用熵值法测算发展水平综合指数,构建环境规制综合评价指标分析环境规制强度,应用固定效应模型分析环境规制、科技创新对成渝地区双城经济圈经济高质量发展的影响机理。结果表明:成渝地区双城经济圈经济高质量发展水平逐步上升但双核城市与周边城市有显著差异;多数城市的环境规制强度总体处于上升趋势,环境规制可以促进经济高质量发展,外资注入和人口聚集导致资源环境矛盾影响经济高质量发展;科技创新对环境规制对经济高质量发展的影响存在中介效应和单门槛效应;同时,环境规制与科技创新可以协同影响经济高质量发展,对经济发展的协同效应呈“U”型变化趋势。因此,应加强双核城市联动和引领作用,加强环境规制与区域环境协同治理,实施科技创新链与低碳产业链深度融合工程。

Environmental regulation and scientific and technological innovation are the important driving forces for the high-quality development of regional economy.Based on the panel data of 16 cities in Chengdu-Chongqing twin-city economic circle from 2014 to 2020,this paper constructed an evaluation system of high-quality economic development based on the new development concept,and calculated the comprehensive index of development level by entropy method.Constructing comprehensive evaluation index of environmental regulation to analyze the intensity of environmental regulation,this paper used the fixed effect model to analyze the influence mechanism of environmental regulation and scientific and technological innovation on the high-quality economic development of the twin-city economic circle in Chengdu-Chongqing area.The results showed that the high-quality economic development level of the twin-city economic circle in Chengdu-Chongqing area had gradually increased,but there was a significant difference between the dual-core city and the surrounding cities;the intensity of environmental regulation in most cities was generally on the rise,and environmental regulation could promote high-quality economic development.Foreign capital injection and population focus leaded to the contradiction between resources and environment,which affected high-quality economic development.Scientific and technological innovation had intermediary effect and single threshold effect in the influence of environmental regulation on high-quality economic development.At the same time,environmental regulation and scientific and technological innovation could synergistically affect the high-quality economic development,and their synergistic effect showed a“U”trend.Therefore,government should strengthen the linkage and leading role of dual-core cities,strengthen the coordinated management of environmental regulation and regional environment,and implement the deep integration project of high-tech innovation chain and low-carbon industrial chain.
