新冠肺炎疫情中政府信任如何影响公众风险感知?——媒介依赖的调节作用The Effects of Government Trust on Public Risk Perceptions during the COVID-19 Pandemic:The Moderating Effect of Media Dependency

摘要(Abstract):
把握公众风险感知的规律并进行合理引导对新冠肺炎疫情防控至关重要。以往研究发现,政府信任是风险感知的主要影响因素之一,但二者之间的关系却未有定论。在新冠肺炎疫情这一突发公共卫生危机事件情境下,政府信任如何影响公众风险感知?媒介依赖会加剧或削弱这种影响吗?本文从挤压效应和遵从效应两个角度来解释政府信任对风险感知的作用机制,基于2020年3月在全国范围开展的配额抽样与便利抽样相结合的问卷调查,使用有序逻辑回归模型对2432份有效问卷分析发现:公众的政府信任负向影响其风险感知水平,公众的媒介依赖发挥调节效应。本文提出的影响机制解释了现有研究对政府信任和风险感知关系的争论,研究结论可以为我国各级政府制定有效的风险沟通策略提供实证支撑。
