摘要
突发事件中社交媒体既显现出实施救灾的能力又传递着大量不实信息,社交媒体场域的不确定性促使公众的风险意识愈发明显。为了解公众风险感知的原因和产生的影响,研究以2020年新冠肺炎疫情为例,采用问卷调查法获取4106个样本,构建媒介信息特征、疫情风险感知和信息分享意愿模型。研究发现,首先,社交媒体使用和官方媒体信息可信度正向影响信息分享意愿。其次,社交媒体使用和官方媒体信息可信度均可通过风险感知影响信息分享意愿,风险感知发挥着中介作用。最后,公众的信息注意偏向也会影响社交媒体使用、官方媒体信息可信度和风险感知的关系,在两两间发挥着调节作用。
Social media not only shows the ability to carry out disaster relief in emergencies,but also transmits a lot of false information.The uncertainty of social media field makes the public’s risk perception more and more obvious.In order to understand the causes and effects of risk perception,this article takes the COVID-19 pandemic as an example,collects 4106 samples by questionnaire survey,and constructs a model of media information cues,risk perception and information sharing willingness.The research shows that the social media use and the credibility of official media information positively affect the information sharing willingness.In addition,both the social media use and the credibility of official media information can influence the willingness to share information through risk perception,which plays a mediating role.Finally,the information attention bias of the public will also affect the relationship between the social media use,the credibility of official media information and the risk perception,which plays a moderating role in two aspects.
