经济集聚、经济密度和城市劳动生产率——基于江苏省的实证研究

Agglomeration,Economic Density&Urban Labor Productivity:Based on Empirical Study in Jiangsu Province

利用1998—2014年江苏省13个地级市市辖区统计数据,以A.Ciccone提出的模型为基础,估测江苏省各城市的物质资本存量和人力资本存量水平,并采用面板数据方法实证分析城市劳动生产率与经济密度的关系。结果显示,江苏省城市劳动生产率对经济密度的影响显著为正,表明该地区存在着集聚经济效应。然而,各区域城市间的集聚经济对城市劳动生产率的作用强度却存在着较大的差异,苏南地区经济集聚的劳动生产率效应最强,苏中和苏北次之。

This paper uses in 1998-2014 Jiangsu Province 13 prefecture level city area statistics,based model is proposed to A.Ciccone,after estimating material capital stock and human capital stock level estimation,using panel data empirical analysis on the relationship between yield and economic density of urban labor students the results show that labor productivity the economic density has a significant positive effect,to verify the region urban agglomeration economic effects. While it differs in different cities,agglomeration economy in the south of Jiangsu Province Labor productivity effect is stronger than that in the middle and north of Jiangsu Province.
