生产性服务业集聚对中国城市经济高质量发展的影响研究

Study on the Influence of Producer Service Industry Agglomeration on the High-Quality Development of Urban Economy

生产性服务业作为现代化经济体系的关键组成部分,已经在中国经济高质量发展的进程中发挥了重要引擎作用,但是目前关于生产性服务业集聚对城市效率的影响机制的研究文献较少。选取2003—2021年中国282个城市的面板数据,运用面板双向固定效应模型实证检验生产性服务业集聚对城市经济高质量发展的影响效应和具体作用机制,研究结果表明:(1)总体上,生产性服务业集聚推动了城市经济高质量发展,并且在考虑稳健性和内生性问题下依然成立。(2)从具体作用机制看,生产性服务业集聚可以通过产业结构升级、技术创新和生态建设三条路径来推动城市经济高质量发展,并且三者都起到正向的部分中介作用。(3)从区域异质性看,生产性服务业集聚对城市高质量发展的促进作用从高到低依次是东部地区、中部地区和东北地区,对西部地区促进作用不显著。

As a key part of a modern economic system,producer services have played an important role in the engine of the process of high-quality economic development in China.However,the currently research literature on the impact mechanism of agglomeration of productive service industries on urban efficiency is lacking.This paper selects the panel data of 282 cities in China from 2003 to 2021,and effectively tests the influence effect and specific action mechanism of the agglomeration of producer services on the high-quality development of urban economy.The results indicate that:On the whole,the agglomeration of producer services has promoted the high-quality development of urban economy,and it is still established despite considering the problems of robustness and endogeneity.From the perspective of specific action mechanism,producer service agglomeration can promote the high-quality development of urban economy through the three paths of industrial structure upgrading,technological innovation and ecological construction,and all of them play a positive intermediary role.From the perspective of regional heterogeneity,the agglomeration of producer services can promote the high-quality urban development in the eastern,central and northeast regions,but the role in promoting the western region is not significant.
