[目的/意义]新冠肺炎疫情使人们再一次认识到新发与再发传染性疾病对人类的巨大威胁，而学术界还缺乏对公共卫生突发事件领域相关软科学发展脉络及其最新研究热点的了解。[方法/过程]文章针对社会科学领域，围绕SARS疫情和世界卫生组织宣布过的6次国际公共卫生紧急事件（PHEIC），利用SciMAT对WoS数据库中有关公共卫生突发事件的文献，进行研究主题的动态演化路径分析。[结果/结论]公共卫生突发事件研究呈持续性稳定增长状态，在2020年受到极大关注；知识演化路径发展状态较平稳，美国及其管理体系、制度经验等主题仍是研究热点；社交媒体与传播方面的研究值得进一步关注与重视。

[Purpose/Significance]The COVID-19 epidemic has once again made people realize the great threat of emerging and re-emerging infectious diseases to human beings.However,the academic community still lacks the understanding of the development of soft science in the field of public health emergencies and its latest research hotspots.[Methods/Process]Focusing on the social science field,this study divided the period of SARS epidemic and the six public health emergencies of international concern (PHEIC) declared by the WHO,and used SciMAT to analyze the dynamic evolution path of the research topics in the literature on public health emergencies based on the WoS database.[Results/Conclusion]The research on public health emergencies is in a continuous and stable state,which will receive great attention in 2020,the development of knowledge evolution path is relatively stable,and the themes of the USA and its management system, institutional experience and so on are still hot spots,the research on social media and communication is worthy of further attention.
