中外COVID-19 科研产出分布比较及我国研究热点分析——以Dimensions COVID-19 数据集为例☆
Analysis of COVID-19 Research Output Distribution and Hotspots: A Case Study of Dimensions COVID-19 Dataset
[目的/意义] 该文旨在比较中外COVID-19科研产出的分布情况、高影响力论文特征以及我国COVID-19研究热点的各个阶段。 [方法/过程] 基于Dimensions的COVID-19数据集,对中国和全球的论文产出规模、出版物类型分布、开放获取情况、高影响力/高提及量论文及其研究主题进行了分析与比较。利用VOSviewer等工具对中国各类型科研产出数量随时间节点的总体变化趋势进行了分析。 [结果/结论] COVID-19论文的主要产出国为美国、中国、英国、意大利和印度。出版物类型上开放获取占大多数。预印本与学术期刊在疫情早期及中期共同承担了加快科研交流的责任,但在疫情后期,预印本发文量逐渐下降,学术期刊发文量持续增加。高学术影响力论文大部分分布在我国,研究主题是通过临床样本揭示新冠肺炎的临床特征、流行病学特征及治疗情况;高提及量论文多数分布在美国等国家,研究主题大多是关于新冠肺炎的起源、公共卫生措施中增加口罩佩戴对预防新冠病毒感染的有效性、在新冠疫情中对政府领导力的谴责、气溶胶传播、新冠肺炎特效药等。另外,在疫情发展的不同阶段,各类型出版物的数量和研究热点均呈现一定程度上的趋势变化,值得进一步研究。
[Objective/Significance] This paper aims to compare the distribution of COVID-19 research output in China and abroad, the characteristics of high-impact papers, and a phased analysis of China’s COVID-19 research hotspots. [Method/Process] Based on the COVID-19 data set of Dimensions, the regional distribution, publication type distribution, open access distribution and publication source distribution of COVID-19 research output in China and the world were analyzed and compared. We also analyzed the regional distribution, publication source distribution and research topics of papers with high academic influence and social concern in the world, VOSviewer and other tools were used to analyze the overall trend of the output of various types of COVID-19 scientific outputs in China over time, and to explore the changing trend of the research hotspots of COVID-19 journal articles at different time points. [Results/Conclusions] The global COVID-19 research output is mainly distributed in the United States, China, the United Kingdom, Italy and India, Open access types are the majority of COVID-19 publications. Preprint and academic journals shared the main responsibility of accelerating scientific research exchanges in the early and middle stages of the epidemic, but in the late stage of the epidemic, the number of preprint publications gradually decreased, while the number of academic journal articles continued to increase. Most of the COVID-19 papers with high academic impact are distributed in China. The research theme of these articles is to reveal the clinical characteristics, epidemiological characteristics, and treatment of COVID-19 through clinical samples. Most of the COVID-19 papers with high mentions are distributed in the United States and other countries. Most of the research topics are about the origin of COVID-19, the effectiveness of adding mask wearing in public health measures to prevent COVID-19 infection, the condemnation to the government leadership in the COVID-19 outbreak, aerosol transmission, and specific drugs for COVID-19. Finally, it is found that in different epidemic development stages, the number of different types of publications and the research hotspots of journal papers show a certain trend of change, which is worthy of further exploratory research.
