中文摘要：
系统评价不仅应重视系统的经济特征，还必须重视系统的非经济特征。在评价系统的非经济特征时必须考虑属性变量，即不能以货币衡量的反映系统非经济特征的定量变量。在过去关于DEA的研究中并未涉及到这种变量。本文对属性变量进行了明确的定义，并提出一种基于属性变量的DEA效率评价模型，最后通过实例演示了模型的合理性。
英文摘要：
Not only the economic characters, but also the non-economic characters should be stressed, while we appraise the performances of a group of systems. In the ease that the non-economic characters are appraised, attribute variables should be included into the consideration, which reflect the non-economic characters and can＇t be measured by economic means. The existing DEA researches have not covered this type of variables. The paper defines the attribute variables, and advances one DEA model based on the attribute variables. Finally a numeral demonstration proves the rationality of our approach.
