通过利用我国35个大中城市的面板数据，采用三阶段DEA方法对我国城市空间扩张的技术效率进行了实证测度。研究表明，经济发展水平对城市空间扩张技术效率的提高有促进作用，而城市人口密度、政府的财政分权程度以及城市面积对城市空间扩张的效率有负面影响；从区域差异来看，城市空间扩张中的非效率因素在东、中、西部地区依次递减：最后，经过调整后的效率值表明，提高规模效率是目前我国城市空间扩张效率提升的主要方向。

Based on the panel data of 35 cities of Chi- na, this essay measures the technical efficiency of China＇ s ur- ban spatial expansion using the three -stage DEA method. The results show that the level of economic development can promote the technical efficiency of the urban expansion, while the urban population density, level of government＇s fiscal decentralization and urban area have negative impacts on the efficiency of urban expansion. When considering the regional differences, the inef- ficiency factors of the urban spatial expansion in the eastern, central and western regions are reduced gradually. Finally, the adjusted efficiency values show that the growth of urban spatial expansion efficiency relies mainly on the improvement of the scale efficiency.
