产业协同集聚如何影响绿色经济效率?--来自中国城市的经验证据

How Does Industrial Collaborative Agglomeration Influence Green Economy Efficiency: Empirical Evidence from Chinese Cities

理论分析产业协同集聚对绿色经济效率的作用机制,并基于中国城市数据实证检验产业协同集聚对绿色经济效率的影响。研究发现:产业协同集聚能够稳健地促进绿色经济效率提升,这一影响效应在东部与中西部皆得到有效验证;产业协同集聚对绿色经济效率的影响因城市规模等级不同而存在一定差异性;生产性服务业细分行业与制造业协同集聚对绿色经济效率的影响也存在一定差异性;产业协同集聚对绿色经济效率的提升作用,更多地体现在对绿色经济技术效率的正向作用上;产业协同集聚通过改善劳动力与资本错配、促进知识溢出与提升环境规制强度影响绿色经济效率。据此,应大力推动产业协同集聚发展,注重产业协同集聚的区域差异与城市规模差异。同时,立足于本地实际,探索高端生产性服务业与制造业协同集聚的发展路径,助推绿色经济效率提升。

This paper theoretically analyzes the mechanism of industrial collaborative agglomeration on green economic efficiency(GEE), and empirically tests the impact of industrial collaborative agglomeration on GEE based on Chinese urban data. The results show that industrial collaborative agglomeration can steadily promote the GEE, and this effect has been effectively verified in different regions of China. The impact of industrial collaborative agglomeration on the GEE varies to some extent due to the scale of cities. There are also certain differences in the impact of producer service sub-industries and manufacturing collaborative agglomeration on the GEE. The promotion effect of industrial collaborative agglomeration on the GEE is more reflected in the technical efficiency of green economy. The research on transmission path shows that the impact of industrial collaborative agglomeration on GEE mainly affects green economic efficiency by improving the mismatch between labor and capital, promoting knowledge spillover and enhancing environmental regulation intensity. Therefore, we should vigorously promote the development of industrial collaborative agglomeration, and pay attention to the regional differences and urban scale differences of industrial collaborative agglomeration. At the same time, based on the local reality, explore the development path of high-end productive services and manufacturing industries, and boost the improvement of GEE.
