摘　　要：针对传统的C2 R-DEA和BC2-DEA模型评价城市土地利用效率的不足,构建了超效率DEA-Malmquist模型,并分析城市土地利用效率。以武汉市为例进行实证分析,首先利用超效率DEA模型测度城市土地利用的超效率值,分析武汉市各区之间土地效率的差异,然后结合Malmquist模型分析武汉市在2010—2016年土地利用效率的动态变化趋势,并进一步探寻土地利用效率变动的根源。研究表明:(1)当有多个DEA有效评价单元时,超效率DEA模型能够完全测度有效评价单元之间效率的高低;(2)Malmquist指数模型能真实地反映城市土地利用效率的动态变动趋势。Aiming at the shortage that traditional C^(2)R-DEA and BC^(2)-DEA in evaluating urban land use efficiency,a superefficient DEA-Malmquist model is put forward to analyze urban land use efficiency.Firstly,the super efficiency DEA model is used to measure the super efficiency of urban land use for Wuhan,and distinguish the efficiency difference between effective decision-making units.Then,the dynamic trend of land use efficiency during 2010—2016 by Malmquist exponential model is analyzed,as well as to explore the source of the disparity.The conclusions are as follows.(1)When there are many effective decision making units,super-efficiency-DEA model can effectively distinguish the efficiency difference between effective decision-making units.(2)Malmquist exponential model can truly reflect the dynamic trend of urban land use efficiency.
