摘要：

目的 为推动我国世界一流科技期刊建设，对比分析我国科技期刊的优势与差异，并提出我国科技期刊影响力提升对策。 方法 基于2023—2025年发布的《期刊引证报告》（JCR）数据，以美国、英国、中国等国家为研究对象，从SCI期刊数量、学科分布、发文量、总被引频次、影响因子、期刊引文指标等维度，分析各国SCI期刊2022—2024年的发展态势。 结果 中国SCI期刊数量在全球总量逐年收缩的背景下保持小幅增长，2024年新增3个学科，影响因子均值与中位数、期刊引文指标均值与中位数均连续3年排名第1，即年指标均值与中位数为各国最高。但中国SCI期刊总量、刊均载文量、学科覆盖度、被引半衰期等指标与美、英存在一定差距，同时，缺少年载文量>1000篇的“大刊”。 结论 中国应进一步扩大总量规模与学科覆盖；推进期刊集群化发展；既要培育高质量期刊，也要创办超级大刊；注重期刊持续影响力建设；注重多维评价，探索符合新发展趋势的期刊评价体系。

Abstract:

Purposes To promote the development of world-class STM journals in China， compare and analyze the strengths and differences of Chinese scientific journals， and propose strategies for enhancing their influence. Methods Based on the Journal Citation Reports （JCR） data from 2023 to 2025， this study examines the development trends of SCI journals in the United States， the United Kingdom， China and etc from 2022 to 2024， focusing on dimensions such as the number of SCI journals， disciplinary distribution， publication volume， total citation， impact factor， journal citation indicators and etc. Findings Despite a global decline in the total number of SCI journals， China’s SCI journal count showed modest growth， with three new disciplines added in 2024. The mean and median impact factors， as well as the mean and median journal citation indicators， ranked first for three consecutive years， indicating the highest annual averages and medians among all countries. However， China’s SCI journals lag behind the U.S. and U.K. in total count， average article output per journal， disciplinary coverage， and half-life of citations， while also lacking “flagship journals” with annual outputs exceeding 1000 articles. Conclusions China should further expand the total number of journals and disciplinary coverage； advance the cluster development of journals； cultivate high-quality journals while also creating super-large journals； prioritize the construction of sustained journal influence； and emphasize multi-dimensional evaluation to explore a journal assessment system aligned with new development trends.
