摘要:

【目的】 了解中国科技人员在国内外发表论文情况,为各级管理部门提供决策依据。【方法】 采用国际权威检索数据库《科学引文索引》《工程索引》《科技会议录引文索引》、Scopus数据库、《医学索引》《社会科学引文索引》以及《中国科技论文与引文数据库》的数据,对中国卓越科技论文、中国科技论文数量、学科和地区分布、基金项目论文、国际合著论文和社会科学论文情况进行统计分析。【结果】 2020年中国卓越科技论文数量为46.38万篇,较2019年增加了19.8%;根据《科学引文索引》数据,2020年中国作者共计发表55.26万篇论文,连续第12年位居世界第2,仅次于美国;2011—2021年(截至2021年10月),中国论文的总被引频次为4332.28万次,与2020年统计时相比,增加了20.2%,位居世界第2;中国平均每篇论文被引用了12.87次,比2020年统计时提高了7.8%,但是仍低于世界平均值13.66次/篇。【结论】 近年来,中国科技论文数量迅速增长,论文影响力的提升速度也相对较快,但篇均被引频次与世界平均值相比还有较大差距。

Abstract:

[Purposes] Scientific papers published at home and abroad by Chinese researchers are analyzed to provide decision-making support for management personnel at all levels. [Methods] Based on important databases, such as Science Citation Index (SCI), Ei Compendex, Conference Proceedings Citation Index-Science, Scopus, Medline, Social Science Citation Index, and Chinese Scientific and Technical Papers and Citations Database, the number of Chinese excellent scientific papers, scientific papers, discipline and region distribution, papers of fund projects, international coauthored papers, and Chinese social science papers were studied and analyzed. [Findings] The number of excellent scientific papers in China were 463.8 thousand in 2020, up 19.8% from 2019. According to SCI, Chinese authors have produced about 552.6 thousand papers indexed by SCI in 2020, ranking the second in twelve consecutive years only to the United States. Chinese papers were cited 43.32 million times from 2011 to October 2021, increasing 20.2% compared with that in 2020. China ranked the second. On average, Chinese papers were cited 12.87 times per paper, increased by 7.8% compared with that in 2020, but lower than 13.66 times per paper, the average rate in the world. [Conclusions] The number of Chinese scientific papers and the improvement of paper impact have increased rapidly in recent years, but the average citation-per-paper rate is still far behind the world average.
