摘要
传统DEA模型将输入输出指标对评价结果的影响等同看待,与实际情况不符.学者们不断尝试运用各种方法对DEA模型中指标的权重进行约束,以体现不同指标重要性的不同.但是,目前的相关研究大多采用主观评价方法,这样会破坏DEA的客观性,而采用因子分析确定的权重是客观的,所以在DEA模型中建立因子约束锥,对权重进行约束,可以在保持DEA客观性不变的基础上体现不同指标重要性的不同.
The traditional DEA model regards the impact of input and output indicators on the evaluation results of the same significance, and it＇s not in compliance with the practice. Therefore, many scholars constantly try to apply various methods to control the weight of indicators in the DEA model, so as to reflect the different importance of different indicators. However, most of existing research takes the subjective evaluation methods, and this undermine the objectivity of DEA model. While the weight of factor analysis is entrusted objectively, thus the paper tries to establish restrain cone of factor in DEA models to control the weight, and the method can reflect the different importance of various indicators without changing the objectivity of DEA model.
