生产性服务业集聚对经济增长的影响效应——基于湖北地区12个地级市的实证分析

Influence Effect of Productive Service Industry Agglomeration on Economic Growth:An Empirical Analysis Based on 12 Prefectural-level Cities in Hubei Region

运用湖北省12个地级市2000—2021年的面板数据,选取双向固定效应模型研究生产性服务业集聚对经济增长的影响和作用机制。研究发现,生产性服务业集聚对湖北地区经济增长的影响效应呈倒U形特征,通过计算拐点值可知,湖北地区现阶段处于倒U形的前半段;从机制检验结果来看,在生产性服务业集聚作用于经济增长的过程中,技术创新表现为部分中介效应,环境规制具有显著调节作用;分区域、分行业下生产性服务业集聚对经济增长的影响存在异质性。

Based on the panel data of 12 prefectura-level cities in Hubei Province for a total of 22 years from 2000 to 2021,a two-way fixed-effects model was selected to study the impact and mechanism of productive service industry agglomeration on economic growth.It is found that the impact of productive service industry agglomeration on economic growth in Hubei is characterized by an inverted U-shape,and except for Wuhan at this stage,the other regions are in the first half of the inverted U-shape.From the results of the mechanism test,in the process of productive service industry agglomeration on economic growth,technological innovation is part of the mediating effect,and environmental regulation has a significant moderating effect.The impact of productive service industry agglomeration on economic growth is heterogeneous in sub-region and sub-industry.
