摘　　要：大量理论研究表明模糊性态度是影响家庭金融决策的重要因素,但相关实证研究尚不充分。通过与国内某头部保险科技平台合作开展问卷调查,测量个体的模糊性态度,并追踪其重疾险购买决策,实证研究发现:第一,个体模糊性厌恶程度与购买重疾险的概率呈正相关关系。平均而言,模糊性厌恶每增加一个标准差,重疾险购买概率提高0.61个百分点。这一结果在控制了风险态度和其他人口统计学特征变量后依然稳健。第二,探究了个体信任水平的异质性影响,发现在缺乏信任的个体中,模糊厌恶程度与重疾险购买概率之间的正向关系会被减弱。第三,模糊性态度对重疾险购买决策的影响在低收入和受教育程度较高的群体中更为显著。研究实证检验了模糊性态度与重疾险购买决策之间的关系,并探讨了与信任的相互作用,为理解模糊性态度对家庭金融决策的影响以及促进商业健康保险市场健康发展提供了政策建议。Extensive theoretical research highlights the significant role of ambiguity attitudes in shaping household financial decisions,yet empirical studies in this area remain scarce.This research,conducted in collaboration with a leading insurance technology platform in China,involved a survey to measure individual ambiguity attitudes and track their critical illness insurance purchasing decisions.The empirical findings are as follows:Firstly,there is a positive correlation between an individual's aversion to ambiguity and the likelihood of purchasing critical illness insurance.On average,a one standard deviation increase in ambiguity aversion is associated with a 0.61 percentage point rise in the probability of buying the insurance.This result holds robust even after controlling for risk attitudes and other demographic characteristics.Secondly,this study explored the heterogeneous impact of individual trust level,finding that among individuals lacking trust,the positive relationship between ambiguity aversion and the probability of purchasing critical illness insurance is weakened.Thirdly,the impact of ambiguity attitude on critical illness insurance purchase decisions is more significant among groups with lower income and higher educational levels.This study is the first empirical test of the relationship between ambiguity attitudes and critical illness insurance purchasing decisions.It also provides insights into understanding the influence of ambiguity attitudes on household financial decisions and promoting the healthy development of the commercial health insurance market.
