集聚效应对中国城市服务业发展差异影响的实证研究

An Empirical Analysis of Agglomeration Effect on Disparity of Urban Services in China

本文从外部经济、知识溢出和社会资本等角度分析了企业集聚、经济集聚状况、城市地理位置与城市服务业发展的关系,并利用分层线性模型(HML)检验了集聚效应对服务业差异的影响。研究结果表明:经济集聚程度对服务业生产效率有显著的正向促进作用,城市区位也对服务业生产效率产生显著影响。东部地区城市比中部或西部地区城市的服务业生产效率高,对服务业发展水平的推动力强;中部和西部具有同质性,二者对服务业效率的影响没有显著差别。

From angle of external economy, knowledge spillover and social capital, the paper discusses the relation between corporation cluster, agglomeration economy, city location and development of urban services. With Hierarchical Liner Modeling, the paper testifies whether there is an agglomeration effect on the disparity of urban services. Results show that agglomeration economy and location of city have significant positive influence on service production efficiency. Cities in eastern China have better production efficiency than central and western China. There are no difference between the central and western China, and they have the same affect on efficiency of urban services.
