中国城市及城市群技术效率差异研究

Study on the Regional Disparity of Technical Efficiency in China's Cities

笔者通过随机前沿分析方法,测算中国不同地理范围的城市技术效率值并对其影响因素做出分析。研究发现,大规模生产资料的投入仍然是我国城市经济增长的主要决定因素;中国城市的生产效率并未出现逐年改进;东部城市群的技术效率一定程度上优于中西部,单个城市的技术效率差异更加明显,现阶段的资源型小城市技术效率优于大中型城市;外资能够与城市技术效率改进形成良性互动,国内资本则反之。

This paper estimates the technical efficiency levels in different regions by SFA and explores their influencing factors. It is found that the amount of input is the main determinant of our urban production. Technical efficiency of China＇ s cities is not improved annually. The degree of technical efficiency in the western region is higher than that in the Midwest region, and the urban disparity of technical efficiency between the small resource-based cities and the large and medium-sized cities. FDI shows a better performance in the improvement of urban technical efficiency, than domestic investment.
