论文摘要
在过去的二十年中，开放访问引文优势（OACA）一直是文献中讨论的主要主题。在本文中，我们提出了一种构成对照组隔离OACA效应的方法。因此，我们将完全OA期刊中2,458,378个出版物的引文影响（MNC）与非OA出版物的对照组（\＃10,310,842）的（加权MNC）进行了比较。同样，在2010 - 2020年期间，我们在混合期刊（\＃1,024,430）及其对照组（\＃11,533,001）的OA出版物中进行了相同的练习。结果表明，在《 OA期刊》中没有出版物的OACA，并且存在劣势。相反，在混合期刊中，OACA似乎是现实，这表明在这种情况下，更好的可访问性倾向于提高出版物的可见性。可以期待在OA期刊上缺乏OACA出版物的出版物，因为OA期刊的很大一部分是新创建的，对高影响力的高级研究人员的吸引力较小。本文的另一个惊人的结果是2016年OACA的沦陷。引用优势从2016年和2020年之间的70％到9％和2020年（用于Hybrid Journals中的70％降至9％）。我们想知道这个秋天是否与2016年海盗站点（例如科学枢纽）的声名狼藉的增加有关。换句话说，海盗站点的民主化立即取消了OA出版物的积极影响，因为访问科学内容的问题不再出现。
The Open Access Citation Advantage (OACA) has been a major topic of discussion in the literature over the past twenty years. In this paper, we propose a method to constitute a control group to isolate the OACA effect. Thus, we compared citation impact (MNCS) of 2,458,378 publications in fully OA journals to that (weighted MNCS) of a control group of non-OA publications (\#10,310,842). Similarly, we did the same exercise for OA publications in hybrid journals (\#1,024,430) and their control group (\#11,533,001), over the period 2010-2020. The results showed that there is no OACA for publications in fully OA journals, and that there is rather a disadvantage. Conversely, the OACA seems to be a reality in hybrid journals, suggesting that a better accessibility in this context tends to improve the visibility of publications. The lack of OACA for publications in fully OA journals is to be expected, as a great proportion of OA journals are newly created and less attractive to high-impact senior researchers.Another striking result of this paper is the fall of the OACA from 2016. The citation advantage fell from 70% to 9% between 2016 and 2020 (for publications in hybrid journals). We wonder if this fall is linked to the increase in the notoriety of pirate sites (eg Sci-Hub) from 2016. In other words, the democratization of pirate sites instantly cancels the positive effect of OA publication insofar as the question of access to scientific content no longer arises.
