This article aims to explore the effects of doctoral publication requirements on the research output of Ukrainian academics in Scopus in terms of quantity and impact. Research output in Scopus, elaborated by Ukrainian academics in economics, medicine and physics who were awarded a doctoral degree in three time periods (before September 2013, after September 2013 and after September 2020) marked by changes in doctoral publication requirements was chosen for analysis. The study findings highlight that the publication requirements resulted in an increase in the share of doctorate holders with publications in Scopus. However, first, the share of PhD holders in economics and medicine who have publications in Scopus remains rather small. In these disciplines, 9.4% and 18.1%, of PhD holders and 44.6% and 47% of DS holders who were awarded a doctoral degree in 2020, have publications in Scopus. This can be attributed to the low standards applicable to doctoral theses in economics and medicine. Second, the median journal CiteScore quartile remained unchanged in all groups except for DS holders in physics. In their case, it rose from 3 to 2. Thus, in general, changes in doctoral publication requirements did not result in doctoral holders publishing in more impactful journals.

博士论文发表要求对 Scopus 中乌克兰学者研究成果的影响

本文旨在探讨博士论文发表要求对乌克兰学者在 Scopus 中的研究成果数量和影响力的影响。Scopus 中的研究成果由在三个时期（2013 年 9 月之前、2013 年 9 月之后和 2020 年 9 月之后）获得博士学位的乌克兰经济学、医学和物理学学者详细阐述，以博士论文发表要求的变化为标志，被选中进行分析。研究结果强调，发表要求导致在 Scopus 中发表论文的博士学位持有者比例增加。然而，首先，在 Scopus 上发表过论文的经济学和医学博士的比例仍然相当小。在这些学科中，拥有博士学位的人分别为9.4%和18.1%，分别为44%和44%。2020年获得博士学位的DS持有者中，分别有6%和47%在Scopus上发表过论文。这可以归因于经济学和医学博士论文的适用标准较低。其次，除了物理学领域的 DS 持有者之外，所有组中期刊 CiteScore 四分位数的中位数均保持不变。在他们的案例中，这一数字从 3 上升到 2。因此，总的来说，博士论文发表要求的变化并没有导致博士持有者在更有影响力的期刊上发表论文。
