摘要
对数据变换下ＤＥＡ有效性问题进行了探讨，给出了ＤＥＡ有效性在一类严格保序函数变换下的一些不变性质。
In this paper,the problem of DEA efficiency under data transformation is further discussed,and some invariant properties of DEA efficiency are provided under a class positive strict isotonic function.In addition,it proves that two efficient production frontiers are equivalent under an order isomorphism.
