产业协同集聚对绿色经济效率的影响

Impact of Industrial Co-Agglomeration on Green Economic Efficiency

制造业与生产性服务业协同集聚作为产业发展的趋势,是实现绿色高质量发展的重要途径。通过选取中国285个城市的面板数据,利用面板门槛模型重点研究制造业与生产性服务业协同集聚对绿色经济效率的非线性关系及行业和区域异质性。研究表明,当以制造业与生产性服务业协同集聚、城市规模、环境规制为门槛变量时,制造业与高端生产性服务业、一般生产性服务业协同集聚对绿色经济效率的影响存在单一门槛,呈倒U形关系。当以经济发展水平作为门槛变量时,制造业与高端生产性服务业、一般生产性服务业协同集聚对绿色经济效率的影响存在双重门槛,呈倒U形关系,且制造业与高端生产性服务业协同集聚对绿色经济效率的影响更大。因此,要因地制宜地推动产业协同集聚,充分发挥市场和政府的优势,科学规划产业布局及监管强度。

As the trend of industrial development,the co-agglomeration of manufacturing and producer services is an important way to achieve green and high-quality development.By selecting panel data from 285 cities in China and using panel threshold model,this paper focuses on the non-linear relationship between the co-agglomeration of manufacturing and producer services on green economic efficiency and its industrial and regional heterogeneity.The research shows that when taking the co-agglomeration of manufacturing and producer services,city size and environmental regulation as threshold variables,there is a single threshold for the impact of the co-agglomeration of manufacturing and high-end producer services and general producer services on the green economic efficiency,showing an inverted U-shaped relationship.When taking the level of economic development as the threshold variable,there is dual threshold for the impact of the co-agglomeration of manufacturing and high-end producer services and general producer services on the green economic efficiency,showing an inverted U-shaped relationship,and the co-agglomeration of manufacturing and high-end producer services has a greater impact on the efficiency of green economy.Therefore,we should promote industrial co-agglomeration according to local conditions,give full play to the advantages of the market and government,and scientifically plan the distribution of industries and supervision intensity.
