论文摘要
中国在科学研究成果中的增长令人印象深刻。学术界对中国与美国之间年度科学出版物生产的跨越时间感到好奇。通过使用Web of Science Core Collection的科学引文指数扩展了数据库，这项研究发现，如果考虑所有文档类型，那么中国仍然是2019年Sci Indexed Publications生产的第二个，但可以超越美国在2020年或2021年。相比之下，中国已经超越了美国，并且是自2018年以来最大的SCI索引原始研究文章制作人。但是，中国仍然落后于美国关于审查纸张生产的数量。通常，定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袖。
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.
