摘　　要：针对交叉效率评价方法中综合效率评价值为1的决策单元不唯一导致的无法比较问题,提出了基于超效率DEA模型的交叉效率评价方法,该方法得到的结果是超效率DEA评价值的均值,而且综合效率评价值大小分布更加合理,能够实现决策单元的全排序。Directed at the problem that cross-efficiency method has more units whose cross-efficiency value equal to 1, a new cross-efficiency evaluation method based on super-efficiency DEA model was put forward in this paper, the value of the method is the mean value of super-efficiency DEA model and the efficiency distribution value of the examples is more reasonable, and all units can be ranked in full order with the method.
