以2003－2012年中国30家寿险公司共247组数据为研究样本，运用SFA方法实证分析了中国寿险公司股权结构与成本效率的关系。在研究中采用超越对数成本函数，构建中国寿险公司随机前沿成本效率模型，将寿险公司的无效率项设成一组效率影响因素和随机因素的函数，考察股权结构对中国寿险公司成本效率的影响。研究结果表明：股权性质对中国寿险公司成本效率的影响不显著，但股权集中度对中国寿险公司成本效率有显著影响。

This paper tests the relationship between the insurance companies'ownership structure and the cost efficiency by applying SFA approach .The sample includes 247 sets of data from 30 life insurance companies in the period of 2003‐2012 .This paper uses the beyond translog cost function ,and respectively establishes stochastic frontier cost efficiency model by setting the inefficiency term of life insurance companies into a function of a series of efficiency‐affecting factors and random factors to accurately analyze the effect of ow nership structure of China's life insurance companies on cost efficiency . T he paper concludes that the nature of equity have no significant effect on the cost efficiency ,w hile the ow nership concentration has a significant impact on both of cost efficiency .
