This paper offers a cross-country and cross-disciplinary analysis of the development of open access publishing from 2000 to 2019. Through an analysis of seven world regions and nine scholarly fields, we found that, while the overall share of open access journals has increased significantly over the last two decades, there are important differences across both the analyzed world regions and disciplines. We also found that, with the exception of neuroscience, the proportion of open access journals is considerably lower among the journals ranked in the Q1 quartile of Scopus than in the general field. We also offer a model that explains the development of open access publishing trends on different disciplinary and geographical levels.

本文对2000年至2019年开放获取出版的发展进行了跨国和跨学科分析。通过对七个世界地区和九个学术领域的分析，我们发现，尽管开放获取期刊的总体份额有所增加在过去的二十年中，重要的是，在所分析的世界区域和学科之间都存在重要差异。我们还发现，除了神经科学之外，在Scopus的Q1四分位数中排名的期刊中，开放获取期刊的比例要比普通领域的期刊低得多。我们还提供了一个模型，用于解释不同学科和地理级别的开放获取发布趋势的发展。
