摘要
给出了有关强DEA有效(C2R或C2GS2)的一些必要条件,判断方法及等价的命题,特别是给出了其存在性定理、及有关强DEA有效与扩展DEA有效等价的定理.
For strong DEA-efficiency （C^2R or C^2GS^2）, in this paper there are its necessary conditions. some methods to judge it and some equivalent propositions. It is emphasized that there is the theorem on its existence and the theorem for strong DEA-efficiency quivalent with extreme DEA-efficiency.
