商业健康保险的配置能够改变家庭的风险偏好吗?--基于CHFS(2017)的实证研究

Influence of allocation of commercial health insurance on family’s risk preference: an empirical research based on CHFS(2017)

将家庭风险偏好分为主观和客观两部分,利用2017年中国家庭金融调查(CHFS)数据,实证研究配置商业健康保险对我国居民家庭主客观风险偏好的影响。利用有序Probit模型估计发现,在控制了人口统计特征和健康状况、家庭的经济状况以及社会保险持有情况等因素,并且有效处理了模型可能存在的内生性问题后,家庭配置商业健康保险会显著提高家庭的主客观风险偏好。异质性分析显示,这种作用效果在低收入家庭中最为明显,在高收入家庭中作用较为微弱。研究结论为加快商业健康保险发展和居民家庭通过理性参与风险金融市场获取财产性收入提供了理论依据。

This paper first divides the risk preference of households into subjective and objective ones. By taking the data from Survey and Research Center for China Household Finance (CHFS) in 2017 as a sample, it then discusses the impact of commercial health insurance on the two types of preference. With the ordered Probit model, it is concluded that after controlling demographic characteristics, health status, family economic status, and social security holding status, the insurance purchasers significantly increase their subjective and objective risk preference. Heterogeneity analysis shows that the effect is remarkable in low-income households. The findings help develop commercial health insurance and improve households’ participation in risk financial market to obtain property income.
