本研究基于OpenAlex分析2018-2024年Scopus除名的514种期刊，发现除名后期刊产出骤降、引用影响变化不大，除名降低了期刊发表吸引力却未同等削弱其作品引用，引发研究诚信担忧。
AI 中文摘要
Scopus等选择性数据库会定期评估其收录的期刊，剔除不再符合质量标准的期刊。期刊被除名后，其后续产出不再被记录，因此这一过程的影响鲜有研究关注。本研究基于从OpenAlex检索到的678162篇文献，分析了2018年至2024年间被Scopus除名的514种来源的发表产出与引用影响，时间窗口为除名前后各三年。采用Wilcoxon符号秩检验对配对样本，按全球、地理区域、知识领域及SJR四分位数检验不同时期的差异。产出在除名年份前持续增长，之后急剧下降；每种期刊的年产出中位数从35篇降至22篇，降幅为37.1%（p<0.001，r=0.30），61.7%的期刊发表量减少，84种（16.3%）期刊在除名后OpenAlex中无记录文献。以三年窗口衡量的单篇文献引用量，在期刊自身对比时几乎无变化，降幅为2.4%（p=0.079）；期刊在引用影响下降与保持稳定或上升之间几乎平分。结果表明，除名使这些期刊作为发表 venues 的吸引力降低，但对其发表作品的引用影响程度未同等削弱，这从研究诚信角度引发担忧。
英文摘要
Selective databases such as Scopus periodically re-evaluate the titles they index and remove those that no longer meet their quality criteria. Once a journal is removed, its subsequent output is no longer recorded, and the consequences of this process have therefore received little attention. This study analyzes the publication output and citation impact of 514 sources delisted from Scopus between 2018 and 2024, based on 678,162 documents retrieved from OpenAlex over a window of three years before and after delisting. Differences between periods are tested with the Wilcoxon signed-rank test for paired samples, globally and by geographic region, field of knowledge and SJR quartile. Output grows until the year of delisting and falls sharply afterwards. The median annual output per journal drops from 35 to 22 documents (-37.1%; p < 0.001; r = 0.30), 61.7% of journals publish less, and 84 (16.3%) have no documents recorded in OpenAlex after delisting. Citations per document, measured over a three-year window, barely change when each journal is compared with itself (-2.4%; p = 0.079), and journals are almost evenly split between those whose impact falls and those whose impact holds steady or rises. The results indicate that delisting makes these journals less attractive as publication venues but does not penalize the citation of the work they publish to the same extent, which raises concerns from a research integrity perspective.
