摘要 

【目的】分析社交媒体中突发公共卫生事件的舆情传播与演变规律, 提出相应舆情监测与舆论引导方案。【方法】基于ELM、TAM模型以及生命周期理论, 建立突发公共卫生事件舆情传播影响因素模型, 探究信息发布者、信息内容以及信息发布日期对舆情传播的影响。【结果】突发公共卫生事件的不同利益群体在舆情发展的不同时期占据舆论主体地位, 时效性强、内容新颖的信息传播更广泛, 官方媒体的发文如果体现出一定的主观性, 其转发量更大。【局限】只对2018年疫苗事件进行实证分析; 在模型普适性验证方面有待提高。【结论】综合考虑信息发布者身份类型、信息内容观点质量以及舆情生命周期的模型能很好地解释突发公共卫生事件在社交媒体平台的舆情传播与演变规律。

Abstract

[Objective] This paper tries to investigate the rules of public opinion propagation and evolution of public health emergencies and propose corresponding policies in the context of social media era. [Methods] Based on ELM, TAM and life cycle theory, the influencing factor model was established to explore the impact of information publishers, information content and information release time on public opinion propagation of public health emergencies. [Results] The empirical analysis showed that the right to discourse is mastered by different interest groups in different periods of public opinion development. Information with great timeliness and novelty spreads more widely. If official media show some subjectivity, the retweet volume of their tweets will be larger. [Limitations] Only one case was empirically analyzed and the compatibility of the model needs to be improved. [Conclusions] The model that comprehensively considers identity of information source, quality of information content and life cycle is a good way to explain the public opinion propagation and evolution rules of public health emergencies on social media platforms.
