摘要：

目的 探讨中国科技期刊卓越行动计划英文医学期刊中的中国与外国论文在颠覆性创新和学术影响力上的差异，为优化我国英文医学期刊稿源结构与质量评价提供论文层面的经验证据。 方法 以入选中国科技期刊卓越行动计划一期和二期的43种英文医学期刊2019年发表的2280篇论文为样本，采用含期刊固定效应的OLS模型，从颠覆性创新和学术影响力2个层面，评估中国与外国论文在学术表现上的差异，并通过替换被解释变量、Oster检验和安慰剂检验验证稳健性，进一步采用分位数回归考察国家效应的异质性特征。 结果 在颠覆性创新方面，中外论文不存在显著差异，该结论在各分位点上均保持稳健；在学术影响力方面，中国论文整体显著优于外国论文，但该优势主要集中在低影响力论文中，在中高影响力论文中差异不再显著。 结论 中国科技期刊卓越行动计划英文医学期刊已在承载和传播本土医学研究成果方面发挥了积极作用，但其稿源质量优势更多体现为基础影响力提升，而非中高影响力论文集聚及颠覆性创新突破。期刊应加大高水平国际稿源吸引力度，优化稿源结构，引导国内学者提升论文学术影响力层次，推动稿源结构由数量优势向质量优势转型。

Abstract:

Purposes This study examines the differences between Chinese and foreign papers published in English-language medical journals supported by the Excellence Action Plan of China’s STM Journals in terms of disruptive innovation and academic impact， thereby providing paper-level empirical evidence for optimizing the manuscript structure and quality evaluation of China’s English-language medical journals. Methods Using a sample of 2280 papers published in 2019 by 43 English-language medical journals selected for Phase I and Phase II of the Excellence Action Plan of China’s STM Journals， an OLS model with journal fixed effects is adopted to evaluate the differences in academic performance between Chinese and foreign papers from the two dimensions of disruptive innovation and academic impact. Robustness is verified by replacing the dependent variables， conducting the Oster test， and performing placebo tests. Quantile regression is further employed to examine the heterogeneous characteristics of the nationality effect. Findings In terms of disruptive innovation， no significant difference is found between Chinese and foreign papers， and this conclusion remains robust across all quantiles. With regard to academic impact， Chinese papers outperform foreign papers overall at a statistically significant level； however， this advantage is primarily concentrated among low-impact papers and becomes non-significant among medium- and high-impact papers. Conclusions English-language medical journals supported by the Excellence Action Plan of China’s STM Journals have played a positive role in disseminating and showcasing domestic medical research. However， the quality advantage of their manuscript pool is manifested more in the elevation of baseline impact than in the concentration of medium- and high-impact papers or breakthroughs in disruptive innovation. These journals should intensify efforts to attract high-quality international submissions， optimize the manuscript structure， guide domestic scholars to elevate the impact level of their research， and facilitate the shift of the manuscript pool from a numerical advantage to a quality advantage.
