摘 要: 本文为了改进C^2R模型反映决策单元相对信息不完全的不足,提出了参数型数据包络分析模型,讨论了这个模型的有关性质,给出了阔值和有效值的概念.经过理论分析和实例验证,这两个值可更好地反映决策单元的相对信息. A parameter Data Envelopment Analysis (DEA) C2R-model is presented in the paper to overcone the shortcoming of the general DEA C2R-model which can't completely reflect the relative information of the Decision Making Units (DMU). The paper not only discusses some property of the parameter DEA C2R-model, but also provides the value-value and effective value concept. By virtue of the theoretical analysis and application, more information can be reflected by the two values.
