同类比较:自2018年以来,中国在SCI索引的研究文章中排名第一

Comparing like with like: China ranks first in SCI-indexed research articles since 2018

Junwen Zhu, Weishu Liu

摘要:

中国科研产出的增长令人印象深刻。学术界对中美之间年度科学出版物数量的交叉何时能够发生感到好奇。通过使用Web of Science Core Collection的Science Citation Index Expanded数据库,本研究发现,如果考虑所有文献类型,中国在2019年仍然排名SCI索引出版物的第二位,但可能在2020年或2021年超越美国成为第一位。相比之下,自2018年以来,中国已经超过美国,成为SCI索引的最大原创研究文章生产国。然而,中国在审查论文的数量方面仍然落后于美国。一般来说,数量优势不等于质量或影响优势。我们认为,美国将在很长一段时间内继续成为全球科学领导者。

英文摘要:

China's rising in scientific research output is impressive. The academic community is curious about the time when the cross-over in the number of annual scientific publication production between China and the USA can happen. By using Web of Science Core Collection's Science Citation Index Expanded database, this study finds that China still ranks the second in the production of SCI-indexed publications in 2019 but may leapfrog the USA to be the first in 2020 or 2021, if all document types are considered. Comparatively, China has already overtaken the USA and been the largest SCI-indexed original research article producer since 2018. However, China still lags behind the USA regarding the number of review paper production. In general, quantitative advantage does not equal quality or impact advantage. We think that the USA will continue to be the global scientific leader for a long time.
