2011—2020年中国省级疾控中心SCI论文发表情况和研究热点

SCI-indexed papers and research hotspots of provincial centers for disease control and prevention in China from 2011 to 2020

  • 摘要: 背景

    新冠全球大流行提示了疾控体系现代化建设的重要性。了解近年来我国疾控体系的科研实力,有利于制定更具针对性的政策或措施以促进疾控体系的现代化建设。

    目的

    了解2011—2020年我国省级疾控的科研水平及其研究热点,为今后疾控机构科研工作发展、学科建设和人才队伍建设提供参考依据。

    方法

    在Web of Science核心合集的科学引文索引扩展版(SCIE)和社会科学引文索引(SSCI)中检索2011—2020年我国31个省级疾控(未纳入台湾省、香港和澳门特别行政区的疾控机构)发表的SCI英文论文,并筛选出以省级疾控为第一单位的文献,进行文献计量分析和可视化分析。文献计量分析包括省级疾控中心(作为合作单位、第一单位)SCI发文情况,不同年份省级疾控(作为第一单位)SCI论文发文量和基金资助情况,省级疾控(作为第一单位)SCI论文的高频作者及其分布、载文期刊特征。采用可视化分析软件Citespace 5.8.R1制作关键词共现图谱、聚类信息表、突现图谱,了解研究热点及其演变进程。

    结果

    2011—2020年我国31个省级疾控的SCI论文数量为8420篇(含合作单位),其中第一单位的论文2060篇。浙江、江苏、上海、北京、山东、广东的省级疾控不论是以合作单位还是以第一单位发表的SCI论文总数均处于前六位。不同省级疾控之间的SCI论文总数差距较大,以第一单位发表SCI论文总数最高的是浙江省疾控(448篇),而数量最低的是新疆疾控(仅1篇)。2011—2020年31个省级疾控以第一单位发表的SCI论文总数总体呈现增长趋势,基金资助率除了2011年为63.1%,其他年份的基金资助率均超过70%。高频作者方面,SCI发文量≥10篇的第一作者共13位,以山东省疾控的Zhang Yingxiu发表的SCI论文量最多(47篇),其次为浙江省疾控的Hu Yu;第一作者SCI发文量≥4篇的人数排名前六的依然是浙江省、江苏省、北京市、广东省、上海市、山东省。期刊特征方面,SCI论文载文量排名前20的期刊总载文量为862篇,占41.8%(862/2060),载文量最高的期刊是PLOS ONE(188篇)。研究热点主要集中于感染、儿童、流行病等领域。前3个聚类类别的主要关键词所涉及的研究领域分别为青少年超重肥胖、艾滋病病毒、疫苗免疫等方面。关键词突现结果显示研究热点从超重、肥胖、体重指数逐渐向抗体、疫苗/疫苗接种、队列等方向转变。

    结论

    近十年我国省级疾控的SCI论文发表量明显增加,基金资助率均处于较高水平,但不同省级疾控间的差距仍然较大,论文发表集中于东部发达省份。研究热点从超重、肥胖、体重指数逐渐向抗体、疫苗/疫苗接种、队列等方向转变。

     

    Abstract: Background

    The COVID-19 pandemic hints at the importance of modernizing disease control system. To understand the scientific research strength of our country's disease control system in recent years is conducive to formulating more targeted policies or measures to promote the modernization of the disease control system.

    Objective

    To understand the scientific research strength and research hotspots of China's provincial-level centers for disease control and prevention (CDCs) from 2011 to 2020, and provide evidence for the development of scientific research work, discipline construction, and talent team construction in CDCs in the future.

    Methods

    The Science Citation Index Expanded (SCIE) and Social Science Citation Index (SSCI) of the Web of Science Core Collection were used to retrieve SCI-indexed English papers published by 31 provincial CDCs (excluding Taiwan Province, Hong Kong and Macau Special Administrative Regions) in our country from 2011 to 2020, and to screen literature with provincial CDCs as the first affiliation for bibliometric analysis and visual analysis. Bibliometric analysis included the SCI-indexed publications of different provincial CDCs (as co-affiliation and the first affiliation), the number of SCI-indexed papers published by provincial CDCs (as the first affiliation) and funding rates by years, the high-frequency authors of SCI-indexed papers published by provincial CDCs (as the first affiliation) and their distribution, and the characteristics of the journals. Visual analysis software Citespace 5.8.R1 was used to draw keyword co-occurrence maps, cluster information tables, and emergence maps to provide information on research hotspots and their evolution.

    Results

    From 2011 to 2020, the number of SCI-indexed papers from 31 provincial CDCs was 8420 (including co-affiliation), of which 2060 papers listed provincial CDCs as the first affiliation. The provincial CDCs of Zhejiang, Jiangsu, Shanghai, Beijing, Shandong, and Guangdong were the leading six institutes in terms of the total number of SCI-indexed papers contributed as co-affiliation or the first affiliation. There was a large gap in the total number of SCI-indexed papers among the provincial CDCs. The highest total number of SCI-indexed papers contributed by provincial CDCs as the first affiliation was Zhejiang CDC (448 papers), while the lowest number was Xinjiang CDC (only 1 paper). From 2011 to 2020, the total number of SCI-indexed papers contributed by the 31 provincial CDCs as the first affiliation showed an overall increasing trend. Except for 2011, which was 63.1%, the funding rates in other years exceeded 70%. In terms of high-frequency authors, 13 first authors published ≥10 SCI-indexed papers: Zhang Yingxiu from Shandong CDC had the highest number of SCI-indexed papers (47), followed by Hu Yu from Zhejiang CDC. Zhejiang, Jiangsu, Beijing, Guangdong, Shanghai, and Shandong still ranked the top six of ≥4 first authored-SCI papers. In terms of journal characteristics, the top 20 journals with the highest number of SCI papers published a total of 862 papers, accounting for 41.8% (862/2060), and PLOS ONE ranked the first (188 papers). The research hotspots were mainly concentrated in the fields of infection, child health, and epidemiology. The main keywords of the first three cluster categories were related to the research fields of adolescent overweight and obesity, HIV, and vaccine immunity. The results of keyword emergence showed that research hotspots shifted from overweight, obesity, and body mass index to antibodies, vaccines/vaccination, and cohorts.

    Conclusion

    The past ten years have witnessed increasing numbers of SCI-indexed papers published by provincial CDCs in our country and a stubbornly high funding rate. However, the gap among the provincial CDCs is still large seeing that economically developed eastern provincial CDCs published more SCI-indexed papers. Research hotspots have gradually shifted from overweight, obesity, and body mass index to antibodies, vaccines/vaccination, and cohorts.
