中美公共卫生领域学术合作的文献分析

Literature Analysis of Academic Cooperation in the Field of Public Health Between China and the United States

目的:分析中美公共卫生领域学术合作发文的特点及变化趋势,为进一步促进两国的卫生学术合作提出循证证据和参考依据。方法:在Web of Science核心合集数据库,检索中美在公共卫生领域学术合作发表的文献,依据美国总统任期划分为5个阶段,基于文献计量分析的方法,对各阶段发文的数量、研究热点、国家主导率以及机构合作特点进行分析。结果:共检索12103篇文献,各阶段的年均发文数量持续增长,拜登政府时期达到最高值1372篇。中国在中美公共卫生学术合作中的主导率不断上升,至奥巴马政府时期超过美国,达到53.92%,在特朗普政府时期最高,为63.57%。5个阶段发文量前10的机构中,中国机构从6个增加到9个,但中介中心性值≥0.1的中国机构数量逐渐减少。结论:中国在中美公共卫生学术合作中的主导地位不断上升,合作的研究热点趋于多样化,但中国机构的学术影响力仍有待提高。

Objective:To analyze the trends and characteristics of Sino-US academic cooperation in the field of public health,so as to provide evidence and references for further promoting health academic collaboration.Methods:The articles published by the Sino-US academic collaboration in the field of public health were retrieved based on the Web of Science Core Collection database.These articles were categorized into 5 stages according to the presidency of the United States.The number of articles,research hotspots,the dominance of countries,and characteristics of institutional cooperation were analyzed at each stage using the method of bibliometric analysis.Results:A total of 12103 articles were retrieved.The average annual number of articles continued to increase across the 5 stages,reaching a peak of 1372 during the Biden administration.The dominant rate of China had been increasing,surpassing the United States during the Obama administration and peaking at 63.57%during the Trump administration.Among the top 10 institutions with the highest number of publications in 5 stages,the number of Chinese institutions increased from 6 to 9.However,the number of Chinese institutions with intermediary centrality values≥0.1 decreased.Conclusion:China's dominance in Sino-US public health academic cooperation is constantly increasing,and the hotspots of cooperation are more diverse.However,the academic influence of Chinese institutions still needs improvement.
