Study of X-Efficiency Based on SFA in Chinese Insurance

本文运用随机前沿法(SFA)对2001-2006年中国29家保险公司的成本/利润效率状况和演进趋势进行了研究。实证结果表明,中国保险公司的成本效率要高于利润效率,并出现了成本效率减速提高与利润效率稳定上升并存的发展态势;无论在成本或利润效率方面,国有保险公司都低于其他所有制保险公司,但在演进过程中与其他所有制公司的差距正在逐步缩小。同时,财产保险公司的平均成本效率要高于人寿保险公司,而人寿保险公司的平均利润效率要高于财产保险公司.

In this paper, we apply the SFA approach to investigate the cost and profit etttciency anct their evolution of 29 insurance companies in China from 2001 to 2006. The empirical results show that the cost efficiency of Chinese insurance companies are higher than the profit efficiency, and show the rise of cost efficiency of slowing down arid the increase of profit efficiency steadily are in the both development trend. Whether the cost efficiency or profit efficiency, State-owned insurance companies are lower than other types of ownership insurance companies, but the gap is gradually narrowing. In the same time, the average cost efficiency of property insurance companies is higher than the life insurance companies, but the average profit efficiency of life insurance companies is higher than the property insurance companies.
