The effects of Open Access (OA) upon journal performance are investigated. The key research question holds: How does the citation impact and publication output of journals switching (“flipping”) from non-OA to Gold-OA develop after their switch to Gold-OA? A review is given of the literature, with an emphasis on studies dealing with flipping journals. Two study sets with 119 and 100 flipping journals, derived from two different OA data sources (DOAJ and OAD), are compared with two control groups, one based on a standard bibliometric criterion, and a second controlling for a journal’s national orientation. Comparing post-switch indicators with pre-switch ones in paired T-tests, evidence was obtained of an OA Citation advantage but not of an OA Publication Advantage. Shifts in the affiliation countries of publishing and citing authors are characterized in terms of countries’ income class and geographical world region. Suggestions are made for qualitative follow-up studies to obtain more insight into OA flipping or reverse-flipping.

转向黄金开放获取的期刊是否显示出 OA 引用或发表优势？

研究了开放获取 (OA) 对期刊性能的影响。研究的关键问题是：期刊从非开放获取转换（“翻转”）到金牌开放获取后，其引文影响和发表产出如何发展？对文献进行了回顾，重点是处理翻转期刊的研究。来自两个不同 OA 数据源（DOAJ 和 OAD）的两个包含 119 和 100 个翻转期刊的研究集与两个对照组进行比较，一个基于标准文献计量标准，另一个控制期刊的国家定位。在配对 T 检验中将转换后指标与转换前指标进行比较，获得了 OA 引用优势的证据，而不是 OA 出版优势的证据。出版和引用作者所属国家的变化以国家收入等级和地理世界区域为特征。建议进行定性后续研究，以更深入地了解 OA 翻转或反向翻转。
