基于WOS与CSCD数据库的中国肝移植学研究文献计量学分析(2001-2020)

Bibliometric analysis of Chinese liver transplantation researches based upon Web of Science and Chinese Science Citation Database between 2001 and 2020

目的探讨2001年至2020年中国肝移植学研究者发表于Web of Science(WOS)科技文献检索工具与科学引文索引(Science Citation Index,SCI)数据库和中国科学引文数据库(CSCD)中论文的分布状况。方法以WOS核心合集和CSCD所收录文献为数据源,统计分析中国肝移植学研究者发表的中英文论文的年索引量与影响力变化状况,论文的来源期刊分布与研究方向,应用Citespace对WOS中收录的中国肝移植学文献共被引网络聚类、研究机构与合作情况、作者发文统计与合作网络进行可视化分析。结果SCI论文所占比例从2020年较2001年增长1370.83%,年均增长速率为68.54%,被引频次从2001年的11次增加到2020年16515次,表现尤为明显。SCI和CSCD论文发文最多的是外科学。科研人员论文研究方向更偏向临床医学技术研究。载文量最多的期刊分别是SCI的《LIVER TRANSPLANTATION》(7.61%)与CSCD的《中华器官移植杂志》(15.57%)。中国肝移植学研究机构、研究者与国内外的大学与研究院所有广泛的合作。结论中国肝移植学论文产出逐年增多,存在国内优秀论文流失现象。国家及科研管理部门坚持正确的政策导向,鼓励和引导科研人员发表高质量的论文选择正确成果平台。

Objective To explore the distribution of science citation index(SCI)and Chinese Science Citation Database(CSCD)papers published by Chinese liver transplantation researchers.Methods Within the core collections of Web of Science™(WOS)and CSCD,annual index and influence changes of both Chinese and English papers published by Chinese liver transplantation researchers from 2001 to 2020 were statistically analyzed.The distribution of source journals and research areas of papers were also analyzed.Citespace was employed for visually analyzing the co-citation network clustering of Chinese liver transplantation literature in WOS,research institutions and cooperations,author published statistics and cooperation platform.Results The proportion of SCI papers spiked by 1370.83%in 2020 as compared with 2001 and the average annual growth rate reached 68.54%.The citation frequency jumped from 11 times in 2001 to 16515 times in 2020.The most published papers in SCI/CSCD were surgery.The research area of scientific researchers was more inclined to clinical medical technology.The most published journals were Liver Transplantation(7.61%)in SCI and Chinese Journal of Organ Transplantation(15.57%)in CSCD.Chinese liver transplantation research institutions and researchers enjoyed extensive cooperations with universities and research institutes at home and abroad.Conclusions The domestic output of excellent liver transplantation papers has skyrocketed yearly.The state and scientific research management departments have adopted correct policy orientations and guided researchers to publish high-quality papers on a proper platform.
