摘要: 本文首次把环境等外生因素纳入中国保险业效率研究的框架中,通过构建多阶段DEA模型,重新测算了中国保险机构1999-2006年共284个样本数据的技术效率、纯技术效率以及规模效率。研究发现,外部环境等因素对效率估计产生了重要影响,中国保险业整体效率水平较调整前出现了明显的下降,而且效率损失主要来源于纯技术无效,说明中国保险业整体效率改进应重点加强技术创新和管理创新,全面提高管理水平。随着保险业市场化进程的不断深入,国有保险机构因依靠相对有利的外部环境使其效率水平被严重高估,中外资保险机构在内部管理水平上的差距却在一定程度上被低估并有拉大的趋势。

Abstract: Considering that part of the inefficiency is due to exogenous circumstances, this paper re-measures the technical efficiency, pure technical efficiency and scale efficiency for the 284 insurance companies in China from 1999 to 2006 by using a multi-stage DEA model. The result shows that the efficiency measures adjusted for environment have been going down, which indicates that external environmental variables have significant impact on the efficiency estimation. With the further opening-up of insurance industry in China, the efficiency of state-owned insurance companies have been over measured, benefiting from the advantageous external environment. And the efficiency gap between foreign and domestic insurance companies show an increasing trend during the sample period.
