经济地理特征与劳动生产率:一个系统性的分析框架

Economic Geography and Labor Productivity: A Systemic Analytic Framework

劳动生产率的地区差距是现实世界中普遍存在的特征性事实。笔者基于中国沿海三大城市群2001年～2010年的面板数据，利用（2009年世界发展报告》的3D分析框架，考察了密度、距离、分割等经济地理特征对劳动生产率差异的影响。研究发现，劳动生产率随着密度的增加而提高，随着距离的增加而减少，分割对劳动生产率的影响不显著。进一步研究还发现，经济地理特征与劳动生产率非线性关系并不明显。本文为理解劳动生产率差异提供了一个系统性的研究视角，对如何促进区域协调发展、提高城市化质量也具有一定的指导意义。

The differences in labor productivity between regions widely exist in the real world. Based on the panel data of three major urban agglomerations in China from 2001 to 2010, this paper, within the 3D framework of 2009 World Development Report, investi- gates how the features of economic geography （ such as density, distance, division and so on） affect the labor productivity between re- gions. Our research shows that the labor productivity will be improved as the density increases, and will deteriorate as the distance in- creases. In particular, the division will have no any impact on the labor productivity. Our further research implies that there is no sig- nificant implication supporting the nonlinear relationship between features of economic geography and labor productivity. These results not only provide a remarkable way of understanding the differences in labor productivity between regions but also have important policy implications for coordinating regional development and improving urbanization in China.
