突发公共事件中感知风险如何影响家庭物资储备行为？

How Does Perceived Risk in Public Emergencies Affect Family Material Reserve Behavior?

摘要: 新冠肺炎的爆发造成了各地居民恐慌、不安的心理，大量抢购物资的现象频发。为探究这一现象的原因，本文通过实地调查问卷方式，从产品性能、社会风险两个维度考察了居民的感知风险，并据此实证分析了感知风险对家庭物资储备的影响和作用机制。研究结果表明，感知风险促进了家庭物资储备行为，其中对生存型物资储备促进作用显著。作用机制和异质性分析表明，政府信任减缓了物价波动风险感知对物资储备行为的促进作用，感知风险对不同家庭储备行为存在显著差异，其中对于低收入组促进效果更强，产品性能风险感知对安庆市和南通市居民促进效果更好，信息关注风险感知对昆山市和南通市促进效果更好，物价波动风险感知对安庆市和昆山市促进作用更强。
