摘　　要：本文利用保险许可证信息和中国健康与养老追踪调查数据,以保险公司分支机构分布衡量保险市场竞争程度,研究了保险市场竞争对家庭商业人身保险参与的影响。研究发现:保险市场竞争显著提高了家庭对商业人身保险的参与广度和深度;保险市场竞争通过降低由投保人承担的隐形交易成本、缓解保险公司与投保人之间的信息不对称、提升家庭的风险意识三种作用机制促进家庭参与商业人身保险;相比于支公司等四级机构,中心支公司及以上分支机构竞争的影响效应更大。在考虑可能存在的内生性问题以及采用保险市场竞争替代指标后,上述研究结论依然稳健。Using a large sample of insurance licenses and data from the China Health and Retirement Longitudinal Study(CHARLS),we examine the impact of insurance market competition(measured by the distribution of insurance company branches)on households'commercial life insurance participation.We find that insurance market competition significantly increases the breadth and depth of participation in commercial life insurance.Insurance market competition promotes commercial life insurance participation through three mechanisms:reducing the hidden transaction costs borne by policyholders,alleviating the information asymmetry between insurance companies and policyholders,and enhancing households’risk awareness.The competition effect in the central branch company and higher branches is greater compared to the fourth-level branches.Our findings remain robust after considering possible endogeneity problems and using alternative indicators for market competition.
