《保险研究》20250603-《公共卫生事件冲击下健康风险与家庭商业保险需求》（黄枫、王东辰）

［摘   要］突发公共卫生事件冲击下，增强家庭的风险保障尤为重要。本文基于最近五次中国家庭金融调查(CHFS)数据，采用双重差分模型，考察了突发公共卫生事件对家庭商业保险购买决策的影响及潜在机制。研究发现，公共卫生事件爆发后，风险暴露强度较高的家庭显著提升了商业保险参保的程度和广度，同时降低了投资风险资产的概率。与健康风险紧密相关的保障型寿险和健康保险参保程度显著增加，且增长幅度随着风险暴露强度递增；而投资型寿险和其他类型保险的参保行为并未受到显著影响。在限定风险偏好稳定的家庭样本中，上述结论仍然稳健，表明健康风险感知强化可能是公共卫生事件影响家庭投保决策的关键传导机制。经济脆弱性较高以及事前健康风险较高的家庭对于风险冲击的投保响应更为强烈。本文的研究为理解中国家庭风险应对和保险规划，并为引导居民形成合理风险感知、优化家庭保险决策提供了政策启示。

Health Risk and Household Commercial Insurance Demands Under the Impact of Public Health Incident

HUANG Feng，WANG Dong-chen

Abstract：It is particularly important to strengthen household protection against risks in response to the impact of abrupt public health incident.Based on the data of the fifth CHFS and using the Difference-in Differences method，this paper examines the impacts of abrupt public health incident on households’ decisions on purchasing commercial insurance plans and its potential mechanism.The study finds that in the wake of the eruption of public health incident，families with higher exposure significantly increase their depth and width of commercial insurance participation，while reducing the probability of investing to risk assets.Specifically，the penetration of protection-type life and health insurance related to health risks rises significantly，and it goes up along with the intensity of exposure.In contrast，the participation to investment-type life insurance and other types of insurance is not affected significantly.When limited to the family samples with stable risk appetite，the above conclusions remain robust，indicating stronger health risk perception might be the key transmission mechanism for public health incident affecting families’ insurance participation decisions.Families with higher financial fragility and higher health risks prior to the event react stronger in insuring against the impacts of risks.The findings of this study may offer some important policy implications for understanding Chinese families’ risk reactions and insurance planning，and for guiding people to develop rational risk perception and optimize their decisions on insurance plan purchase.
