摘　　要：本文利用2003—2011年中国城市面板数据,建立空间计量模型,考察经济集聚对城市劳动生产率的影响。根据柯善咨、向娟(2012),文章修正了现有文献忽略城市资本存量所导致的内生性偏误,以得到更加可靠的估计结果。研究表明,控制了城市资本存量、产业结构、人力资本、财政支出和基础设施等因素后,经济集聚对城市劳动生产率有着显著为正的作用,作用强度在城市间存在差异:东部城市经济集聚的劳动生产率效应强于西部城市,弱于中部城市。同时,邻近城市的劳动生产率会相互促进,即存在劳动生产率的空间溢出,这在东部城市中最为明显。研究结论为中国城市劳动生产率差异提供了一种经济集聚视角的解释。In this paper, we use panel data during 2003 -2011 in Chinese cities and establish spatial e- conometric models to investigate the economic agglomeration effect on the city labor productivity. According to Ke Shanzi and Xiang Juan （2012） , correcting the endogeneity bias caused by the ignorance of the city capital stock in existing literatures to get more reliable estimation results. The results show that, after controls of city capital stock, industrial structure, human capital, financial expenditure and infrastructure, economic agglom- eration has a significant positive effect on urban labor productivity. And there are differences in the effect a- mong cities： labor productivity effect of economic agglomeration in eastern cities is stronger than that in west- ern cities, weaker than that in central cities. At the same time, the neighboring city will promote each other in labor productivity, namely the existence of spatial spillover of labor productivity, which is most obvious in the eastern cities. Research conclusion provides a perspective of agglomeration economic explanation for China＇s urban labor productivity differences.
