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 and 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 are 480.5 thousand in 2021, up 3.6% from 2020. According to SCI, Chinese authors have produced about 612.3 thousand papers in 2021. Chinese papers are cited 57.0699 million times from 2012 to October 2022, increasing 31.7% compared with that in 2021. Total cites of Chinese papers rank second in the world. On average, Chinese papers are cited 14.34 times per paper, increased by 11.4% compared with that in 2021, but lower than 14.72 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 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、MEDLINE、《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数量、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】 2021年中国卓越科技论文数量为48.05万篇,较2020年上升了3.6%。根据《科学引文索引》数据,2021年中国作者共发表61.23万篇论文。2012—2022年(截至2022年10月),中国论文的总被引频次为5706.99万次,与2021年统计数据相比,增加了31.7%,位居世界第2。平均每篇中国论文被引用14.34次,该数据比2021年提高了11.4%,但是仍低于世界平均值14.72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差距。
