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。
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 the adjusted efficiency is lower than pre-adjustment,which indicates that external environment has an important impact on efficiency.And the efficiency gap between foreign and domestic insurance companies shows an increasing trend during the sample period.
