基于Malmquist-DEA模型的产险公司再保险效率实证研究

摘要

Based on Malmquist-DEA model,this paper measures the reinsurance efficiency of 22 primary property insurance companies in the mainland of China range from 2003 to 2013 and develops a panel data model to test different determinants of cession efficiency. The findings show that the reinsurance efficiency was on the rise within the sample period, the technological efficiency change is the main driving force,the scale efficiency change enhances the technology efficiency. The diseconomies of scale and the increase of claim drag the reinsurance efficiency down. The complement of owners'' equity and the expansion of premium scale strengthen the primary insurers'' bargain power.%基于Malmquist-DEA模型测度了我国大陆地区22家产险公司2003—2013年的再保险效率,并在此基础上构建了分析产险公司再保险效率影响因素的Panel data模型,实证研究表明,样本期内产险公司的再保险效率整体上呈上升趋势,源自技术效率变动的"追赶效应"推动了这一上升,规模效率的提升则推动了技术效率的变动.分保上的规模不经济和赔付率的上升阻碍了各产险公司再保险效率的提升;自身资本实力和业务量的增加提高了分出人的谈判能力.
