Abstract:

[Purposes] This paper aims to explore the contribution of papers on COVID-19 to journal impact factor, so as to deepen the understanding of the essential characteristics of journal impact factor and provide suggestions for improving the influence of Chinese journals and a reference for rationally evaluating scientific journals. [Methods] In view of the inflationary growth of journal impact factor based on JCR 2022 issued by Clarivate, about 3.64 million publications (with 33000 papers on COVID-19) and 18.64 million citations of 11000 journals were quantitatively analyzed. The relationship between the contribution rate and citation of papers on COVID-19 and the increase in journal impact factor was investigated, and the contribution of papers on COVID-19 to journals of different divisions and subject areas and the impact factor of Chinese journals was explored.[Findings] Papers on COVID-19 have positive effects on the impact factor of 87.0% of journals and have a contribution of 31.1% to the increase in impact factor. As the JCR quartile of the journal gets higher, the contribution of papers on COVID-19 is greater. This effect is observed not only in the fields of clinical medicine, psychiatry, and psychology but also in fields such as biology and chemistry. The impact factor of Chinese journals increases rapidly, and papers on COVID-19 have played an important role, contributing 20.5% to the increase in impact factor. [Conclusions] Scientific research on COVID-19 has contributed to the increase in the impact factor of most journals. In the face of such major emergencies, Chinese journals should seize research frontiers and hotspots, enhance emergency publishing capabilities, and improve academic influence and brand recognition. At the same time, more robust indicators and more fine-grained classification systems should be explored to meet the great challenges brought by such emergencies to the scientific research evaluation system.

摘要：

【目的】探究新冠论文对期刊影响因子的贡献情况,深化对期刊影响因子本质特征的认识,以期为中国期刊影响力的提升和发展建设提供参考,同时为科技期刊的合理评价提供参考。【方法】根据科睿唯安发布的2022年度JCR中期刊影响因子猛增的现象,对1.1万种期刊发表的约364万篇论文(新冠论文约有3.3万篇)及1864万条引用数据进行定量分析,探究新冠论文被引、新冠论文贡献率与期刊影响因子增幅之间的关系,系统揭示新冠论文对不同分区、学科领域期刊及中国期刊影响因子的贡献。【结果】新冠论文对87.0%的期刊的影响因子有正向贡献,对影响因子增幅的贡献率为31.1%,且期刊所在JCR分区越高,新冠论文贡献越大。新冠论文的影响范围不限于临床医学和精神病与心理学领域,生物、化学等领域同样受到较大影响。中国期刊影响因子提升较快,新冠论文是重要助力,对影响因子增幅的贡献率达到20.5%。【结论】“新冠化”科学研究为绝大多数期刊影响因子的提升作出贡献,未来中国期刊在面对此类重大突发事件时,应善于抓住研究前沿和热点,增强应急出版能力,提升学术影响力和品牌辨识度。同时,要探索更鲁棒的指标、更细致的分类体系来应对此类突发事件为科研评价体系带来的巨大挑战。
