中文摘要:利用我国非寿险公司2001~2007年的财务数据，采用分位数回归方法探讨非寿险公司赔款准备金调整的动机，并比较非寿险业务准备金评估方法改变前后公司实现盈余管理动机的差异。研究发现，非寿险公司存在实现盈余管理的现象，相比规避递延税收的目的而言，管理层故意调整公司当年赔款准备金数字进行盈余平滑的动机更为显著。当公司当期盈余表现差于前一期时，管理者倾向于低估当期赔款准备金提升账面盈余；若当期盈余表现优于前一期时，则高估准备金平滑盈余。在当年承保业务不佳，赔付率较高时，非寿险公司具有低估准备金掩饰承保质量的动机。2005年非寿险业务赔款准备金评估方法的改变，显著增强了非寿险公司利用赔款准备金进行盈余管理的动机。

Claims Reserve and Earning Management in Non life Insurers: Evidence from Chinese Market

Abstract:Based on the 2001~2007 financial data of non life insurer in China, using quartile regression method, we investigate the motives of reserving manipulating for non life insurers, and analyze whether the motives have some changes before and after the evaluation method change of claim reserve. We find, non-life insurers have some motives for earning management. Compared with tax deferred motives, the insurers have more significant motive to earning smoothing by manipulating claim reserve deliberately. When the earning is lower than that of last period, the insurers may underestimate the claim reserve to increase the book earning, when the profit earning better than that of last period, overestimating the claim reserve is more likely occurred. Moreover, the insurers tend to underestimate loss reserve for masking the fact of worse underwriting performance. As an interesting phenomenon, we find that the change of evaluation method for claim reserve in 2005, reinforces the motive of manipulating loss reserve to manage earning for non life insurer.
