2018年中国科技论文统计与分析简报

A brief report of statistics and analysis on Chinese scientific papers in 2018

【目的】了解中国科技人员在国内外期刊发表论文情况,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、中国科技论文数量及引用、学科和地区分布、国际合著论文、中国科研机构创新发展、基金项目论文和社会科学论文情况进行统计分析。【结果】2018年中国卓越科技论文数量为31.59万篇,较2017年提高了12.4%;根据《科学引文索引》数据,2018年中国作者共计发表论文41.82万篇,连续10年位居世界第2,仅次于美国;2009—2019年(截至2019年10月),中国论文的总被引频次为2845.23万次,与2008—2018年相比,增加了25.2%,位居世界第2;中国平均每篇论文被引用10.92次,比2008—2018年提高了9.2%,但是仍低于世界平均值12.68次/篇。【结论】近年来,中国科技论文数量增长迅速,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。

[Purposes]Scientific papers published at home and abroad by Chinese researchers are analyzed to provide decisionmaking 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,the number of scientific papers and citations distribution,discipline and region distribution,international co-authored papers,the innovative development of scientific research institutions in China,papers of fund projects,and Chinese social science papers were studied and analyzed.[Findings]The number of excellent scientific papers in China were 315.9 thousand in 2018,up 12.4%from 2017.According to SCI,Chinese authors have produced about 418.2 thousand papers indexed by SCI in 2018,ranking the second in ten consecutive years only to the United States.Chinese papers were cited 28.45 million times from 2009 to October 2019,increasing by25.2%compared with that in 2018.China ranked the second.On average,Chinese papers were cited 10.92 times per paper,increased by 9.2%compared with that in 2018,but lower than 12.68 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.
