中文摘要：
决策单元进行效率评价与排序是被广泛关注的研究领域，数据包络分析方法已经被广泛运用于决策单元的排序之中．然而，绝大部分DEA排序方法都是基于自评效率，即每个决策单元都选择对自身有利的权重，这样的效率不具备可比性．因此，提出一种基于公共权重DEA模型的决策单元排序方法．此方法包含四个步骤，每个决策单元的效率值分解为两部分，即自身的技术效率与其权重偏好结构获得其他决策单元认可的程度．用一个算例分析对该方法进行了演示．
英文摘要：
Efficiency rating and ranking are of great academic value and practice importance, and have been paid more and more attention. DEA has been accepted as a useful ranking tool. However, almost all DEA- related ranking approaches are based on the self-evaluation efficiencies. That is to say, each DMU chooses its most favorite weights, and the resulted efficiencies have little meaning as ranking base. Therefore this paper advances a ranking technique based on a common-weight DEA model. In the four-step model each DMU＇s efficiency score is decomposed into two parts： one is the technical efficiency, and the other is the acceptance degree of its weight preference structure. A numeral example is given to demonstrate the approach.
