| 摘 要： | 运用DEA优势效率模型和劣势效率模型对我国9家保险公司2001年度的DEA综合效率进行测评显示:它们的效率总体上不占优势;运用CCR模型进行Charnes-Cooper线性变换和对偶变换后的模型(D),分析它们2001年的规模效率情况,结果表明大多存在非规模经济现象;运用回归模型分析综合效率、所有制形式对它们总资产报酬收益率的影响,得出总资产报酬收益率与上述两个因素显著正相关.

| Abstract: | This paper uses DEA advantage efficiency model and disadvantage efficiency model to make an assessment for nine Chinese insurance companies' DEA comprehensive efficiency in 2001.The result shows that they do not win advantage as a whole.After doing Charners-Cooper linear transformation and dual transformation using the CCR model,a model(D) is obtained.This model is used for examining their comprehensive efficiency,and we found that large-scale economy is not apparently in them.A regression model is used and a conclusion is obtained that the gross assets revenue rate(Y) of these companies has positive relationship with the comprehensive efficiency(EFF) and ownership(OWNER) form. |
