摘要
DEA模型作为一种客观的多指标决策方法应用十分广泛。但目前使用频率较高的两种通用模型C2R模型和C2GS2模型,在单独使用时都有比较大的局限性,评判结果往往无法令人满意;针对这一问题,本文提出构建混合DEA模型,并应用混合DEA模型对医药上市公司的经营效率相对有效性评价进行实证分析,阐述了混合DEA模型的使用方法,验证了评判方法的可行性和科学性。
The DEA model is widely used to evaluate the relative efficiency as a kind of objective decision method with multiple indexes, but the two basic models, the C^2R model and the C^2GS^2 model, which are frequently used at present, meet limitations while they are used alone, the evaluation results are often unsatisfactory. In order to solve this problem, a mixed DEA model has been built in this paper, and it is used to evaluate the validity of the business efficiency of listed companies. At the same time, the paper explains how to use this mixed DEA model, and has verified the feasibility and rationality of the model.
