摘    要:本文提出了一种基于两阶段DEA的企业效率评价方法,将决策单元的复杂生产过程分为前后相续的两个子过程,在考虑子过程之间关联关系的基础上,建立两阶段关联DEA效率评价模型,进行企业效率分解和评价。关联DEA模型克服了传统的独立DEA模型的缺点,可为决策单元改进绩效提供更加充分的信息。以21家财产保险公司为样本的实证分析指出了非有效公司效率低下的原因和需要改进的领域。实证结果表明中资财产保险公司在营销方面比外资公司较有效率,但盈利能力效率低于外资财产保险公司。根据效率评价结果本文构建了一个效率矩阵,将样本财产保险公司分为四类,针对不同类型的公司提出了相应的绩效改进策略和建议。

关 键 词:企业效率  数据包络分析  财产保险公司  营销效率  盈利效率

Abstract:This paper puts forward a two-stage correlative DEA model to measure firm efficiency.The complicated production process of decision making units is decomposed into two sub-processes,and the efficiency of the whole process is decomposed into the product of the efficiencies of the two sub-processes.The correlative DEA model overcomes the disadvantages of independent DEA model by considering the series relationship of sub-processes within the whole production process;it is more reasonable and reliable in measuring the efficiencies and identifying the inefficient field to improve.An empirical study on 21 property insurance companies in China is conducted.The results indicate the inefficient field to be improved for those inefficient companies.Domestic property insurance companies are more efficient in marketing than their foreign counterparts,but are less efficient in profitability.Based on the efficiency results,an efficiency matrix that divides the sample companies into four types is established,some suggestions are provided for property insurance companies in China to improve their performance.
Keywords:firm efficiency  data envelopment analysis  property insurance company  marketing efficiency  profitability efficiency
