| 摘 要： | 在传统DEA模型基础上提出了交叉效率模型,利用传统的和交叉效率DEA模型对湖南省14个市洲的耕地利用效率进行动态评价.结果表明,湖南省耕地利用效率整体不高,就各市州来说,株洲市耕地利用效率最高,达0.876 4;张家界市的最低为0.596 7.基于交叉效率的计算,发现了3个在传统模型中出现的伪有效地区：怀化市、娄底市及湘西州.最后利用聚类分析,以投入作为变量,将14个市（州）分为3组,确立了相应的基准区域.

| Abstract: | A dynamic evaluation was conducted on the cultivated land using efficiency of 14 cities in Hunan Province based on DEA model, a cross-efficiency model based on the traditional DEA model was put forward, the introduction of cross-efficiency effectively solve the defects of tra- ditional model. The results revealed that： the whole efficiency of cultivated land use in Hunan Province is not efficient, none of the cities have reached 1. 000. The highest efficiency of cultivated land use is Zhuzhou City, reached 0. 876 4, the lowest is Zhangjiajie City, reached 0.596 7. Based on the calculation of cross-efficiency, it was found that there are three ＂false positive＂ cities in traditional DEA model, they are Huaihua City, Loudi City and Xiangxi State. Finally, using cluster analysis, and regards the inputs as the variable, 14 cities were divided into three groups to establish a benchmark region. |
