中国城市效率差异及其影响因素——基于地级及以上城市面板数据的研究

使用2001~2007年中国266个地级及以上城市的投入产出数据,传统的DEA方法与超效率DEA方法相结合,分析了中国城市效率的变化趋势和空间差异,重点探讨各种城市条件因素对城市效率的影响特征。结果显示,中国城市效率较低且空间差异明显,各城市效率类型不但统计特征十分明显,而且地域分布上存在很明显的集聚特征。各种城市条件因素通过影响纯技术效率和规模效率并进一步地综合作用于城市效率,并且表现出截然不同的特征。

Empirical Research on the Chinese Urban Efficiency and Its Influencing Factors

Using input and output data of 266 prefecture-level cities from 2001 to 2007 in China,combining the method of traditional data envelopment analysis and super-efficiency DEA,this article analyzes the trend of urban efficiency and the spatial differences,and focuses on the various characteristics that urban conditional factors affects the efficiency of the city.The results showed that Chinese cities are less efficient and space discrepancy of urban efficiency is significant,the various types of cities not onl...
