突发公共卫生事件研究的趋势和特征——基于CiteSpace的知识图谱分析

Trends and Characteristics of Public Health Emergencies——Knowledge Mapping Analysis Based on CiteSpace

【目的/意义】系统认识我国突发公共卫生事件研究的全局特征,对我国突发公共卫生事件研究的热点和趋势进行研究,可以为后续学者的研究提供有益的方向性参考。【设计/方法】采用文献统计方法,基于CiteSpace软件处理文献数据,运用数据挖掘思维对科学计量知识图谱进行分析,选择CNKI核心数据库中2003~2019年发表的突发公共卫生事件的论文作为研究对象,分析17年的发文量、研究机构、作者以及关键词的变化趋势。【结果/发现】2003~2010年,是该领域发展黄金期,2010年后研究量有所下降;论文发表机构从疾病防控中心等机构逐步转移到高校,作者呈现时间聚集效应;研究主要聚焦于应急机制、流行病学、公共卫生体系和疾病预防控制等方面,对突发公共卫生事件的应对和管理研究具有重要的理论借鉴价值。

[Purpose/Significance]In order to systematically understand the overall characteristics of research on public health emergencies in China,we researched the hotspots and trends of public health emergency research in China to provide useful directional references for the follow-up scholars’research.[Design/Methodology]This paper uses literature statistical methods,processes literature data by CiteSpace software,analyzes scientometric knowledge maps using data mining thinking,selects papers on public health emergencies published in the CNKI core database from 2003 to 2019 as the research object,and analyzes the trends of the number of articles published,research institutions,authors,and changes in keywords in the 17 years.[Findings/Conclusions]The period between2003 to 2010 was the golden period for the development of this field,and the amount of research gradually declined after 2010;the publication centers of the papers gradually shifted from the disease prevention and control centers to universities,and the authors showed a time clustering effect;the researches mainly focused on emergency response mechanism,epidemiology,public health system and disease prevention and control,which had important theoretical reference value for the research on response and management of public health emergencies.
