| 摘 要： | 主要探讨了DEA中的两个基本模型．首先，简要回顾了有关DEA模型的研究进展；接着，介绍了DEA研究中常用的两个基本模型：CCR模型及BCC模型，以及基于CCR模型的其他相关模型；最后，对CCR模型和BCC模型做了比较分析，并指出CCR模型和BCC模型各自的生产可行性／可能性集合是不同的．因此，CCR模型的边界具有线性特征，而BCC模型的边界具有分段线性特征，并呈现凹特性．

| Abstract: | This paper mainly discussed on the two basic models of data envelopment analysis. Firstly, the study of DEA models was briefly reviewed; and then, the two basic DEA models, CCR model and BBC model, and other transformed formats based on CCR model were presented and discussed; lastly, a comparison between CCR model and BCC model was made and the result shows that the set of feasible activities, which is called production possibility set, is different for the CCR model and for the BCC model respectively. The frontiers of the CCR model have linear characteristics, while those of the BCC model have piece-wise linear and concave characteristics. |
