内容简介：The classic DEA model is called the black box model, because that it cannot analysis the structure of the Decision making unit. The network DEA model have been set up from 1996, it can measure the overall efficiency of the DMU with intermediate product or intermediate input. That means it can open the black box. In many cases DMUs may consist of two-stage network structures with intermediate measures, and there are plenty of research of network DEA in methodology and applications. In this paper, we compare with several different network DEA models with two stages series structure, and prove the relationship of them. Then we want to show which models can really open the black box. At the end, we measure Chinese commercial banking overall efficiency and sub-stage efficiency using these models.
