2022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 2022

【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】2022年中国卓越科技论文数量为59.58万篇,较2021年上升了24.0%;根据《科学引文索引》数据,2022年中国作者共计发表73.56万篇论文;2013—2023年(截至2023年8月),中国论文的总被引频次为6748.23万次,与2022年统计时相比,增加了18.3%,位居世界第2;中国平均每篇论文被引用15.19次,比2022年统计时提高了5.9%,但是仍低于世界平均值15.85次/篇。【结论】近年来,中国科技论文数量迅速增长,论文的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。
