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 numbers of Chinese excellent scientific papers, scientific papers, discipline and region distribution, funded papers, international coauthored papers, and Chinese social science papers were studied and analyzed. [Findings] The number of excellent scientific papers in China was 387.3 thousand in 2019, up 22.6% from 2018. According to SCI, Chinese authors have produced about 495.9 thousand papers indexed by SCI in 2019, ranking the second in eleven consecutive years only to the United States. Chinese papers were cited 36.06 million times from 2010 to October 2020, increasing 26.7% compared with that in 2019. China ranked the second. On average, Chinese papers were cited 11.94 times per paper in 2019, increased by 9.3% compared with that in 2018, but lower than 13.26 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.

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】 2019年中国卓越科技论文数量为38.73万篇,较2018年增加了22.6%;根据《科学引文索引》的数据,2019年中国作者共计发 表49.59万篇论文,连续第11年位居世界第2,仅次于美国;2010—2020年(截至2020年10月),中国论文的总被引频次为3605.71万次,与2018年的统计结果相比,增加了26.7%,位居世界第2;中国平均每篇论文被引用了11.94次,比2018年的统计结果提高了9.3%,但是仍低于世界平均值13.26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。
