| 摘 要： | 针对传统数据包络分析(DEA)模型不能对有效决策单元做进一步比较的现实情况,文章引入了重新定义生产可能集的SE-DEA模型,创造性地克服了传统模型的这一缺点,实现了对所有决策单元的充分评价与排序.接着以沪深股市火力发电上市公司为例进行实证,在论证它们符合SE-DEA模型应用假设条件的基础上,验证了该模型在评价企业效率方面的有效性.

| Abstract: | For the reason that conventional data envelopment analysis(DEA) model cannot make further comparison among the efficient ones in evaluating the relative efficiency of decision-making units,this paper proposes the super-efficiency DEA model,which is the extending of the original one and can successfully solve this problem.Finally,twenty power corporations selected from Shanghai and Shenzhen stock market are rendered to substantiate its validity. |

| Keywords: | super-efficiency data envelopment analysis model relative efficiency decision-making units power corporations |
