摘　　要：随着我国城市化进程的加速,产业集聚给城市经济带来了多层面的影响。基于理论上的可能性,本文提出产业集聚与城市经济增长的非线性假设,并使用我国城市数据和Panel 2SLS计量模型加以验证。我们将城市产业集聚进行了结构和行业的细分,结构上分为专业化集聚、多样化集聚与城市经济规模集聚,行业上分为工业与服务业两种产业的集聚。研究发现,服务业的专业化和多样化集聚与城市经济增长都存在显著的U形关系,说明这两种集聚带来的拥塞效应快于对经济的促进作用,并且,我们以就业密度为指标计算U型拐点是665人/Km2。而工业集聚中无显著的非线性关系,城市经济规模变量与经济增长之间一直存在着稳定的倒U形关系。With the acceleration of China＇ s urbanization, agglomeration brings different effects on urban e- conomy. Based on many theories, we assume that there is a nonlinear relation between agglomeration and urban economic growth, and test this hypothesis by city data and panel 2SLS model. This paper divided the agglomeration into three types and two industries. Agglomeration types include MAR agglomeration, Jacobs agglomeration and urban economic scale. The agglomeration industries include industry agglomeration and service agglomeration. We find that, there is a U shape relation between service agglomeration and urban economic growth, and the employment density turning point is 665 people per square kilometer. However, there is no significant nonlinear relation between industry agglomeration and urban growth.
