Chinese authors published as many papers as American, British, German and Japanese researchers combined in 2025.(2025年，中国作者发表的论文数量与美国、英国、德国和日本研究人员之和相当。) Yet two recent analyses drawing on(利用) databases of tens of millions of English-language scientific articles suggest they were largely overlooked(被忽视) by Western researchers. That is not for lack of value: China leads the Nature index, a ranking of countries by number of papers published in a set of respected journals.
2025年，中国作者发表的论文数量与美国、英国、德国和日本研究人员之和相当。然而，两项基于数千万篇英文科学文章数据库的最新分析表明，这些论文在很大程度上被西方研究人员忽视了。这并非因为缺乏价值：中国在自然指数（根据在若干知名期刊上发表论文数量对各国进行排名）中领先。
The second analysis, posted by a Chinese-Dutch team on the preprint(预印本) server arXiv(① 背景：arXiv（发音为“archi...) in April, found that even though American, British, French, German and Japanese teams have become more likely to(更有可能) cite Chinese research since 2000, citations of Chinese work in 2022 were still much lower than expected based on factors like the quantity of scientific output. There was a striking imbalance: Chinese researchers cited American work more than expected; American researchers cited Chinese work less than expected.(存在显著的不平衡：中国研究人员引用美国论文的次数高于预期；而美国研究人员引用中国论文的次数低于预期。)
第二项分析由一个中荷团队于4月发表在预印本服务器arXiv上。该分析发现，尽管自2000年以来，美国、英国、法国、德国和日本团队引用中国研究的可能性有所增加，但2022年中国研究的被引次数仍远低于根据科学产出数量等因素预期的水平。存在显著的不平衡：中国研究人员引用美国论文的次数高于预期；而美国研究人员引用中国论文的次数低于预期。
Some of this may be artefact(假象). The first result could be swayed by colleagues excessively citing each other’s work to drive up(推高) metrics(指标). The second does not account for(解释；占) differences in the average quality of science done in each place.
这其中有些可能是人为假象。第一个结果可能受到同事之间过度互相引用以提高指标的干扰。第二个分析没有考虑各地科研平均质量的差异。
