The systematic review of the research reported in this paper was conducted within the context of efforts to understand and combat predatory publishing, a new but fast-growing area of research. It synthesizes the trends observed in knowledge production in predatory publishing, with a particular focus on the volume and distribution over time within different journals. It also looks at the composition of the predatory publishing literature in terms of the type of study, methods, topics, field of study, and contexts where research was conducted. Data were extracted from ERIC, Web of Science, and Scopus and identified 228 articles for evaluation published in 171 journals. The results demonstrate that the literature on predatory publishing is new but fast growing, with 88.6% of studies published since 2016. Only 37.3% reported empirical research, and the majority of these were quantitative studies with weak statistical tests. Medical journals carried the most articles. We conclude that scholarship on predatory publishing is in the early stages of development, and it is thinly distributed across journals, fields, and research contexts. It was surprising to find no studies in leading higher education journals, and this study reveals a research area that is still developing.

掠夺性出版的知识生产：系统评价

本文报告的研究的系统回顾是在努力理解和打击掠夺性出版的背景下进行的，掠夺性出版是一个新的但快速发展的研究领域。它综合了掠夺性出版知识生产中观察到的趋势，特别关注不同期刊随时间推移的数量和分布。它还根据研究类型、方法、主题、研究领域和进行研究的背景来审视掠夺性出版文献的构成。从 ERIC、Web of Science 和 Scopus 中提取数据，并确定了 228 篇发表在 171 种期刊上的文章进行评估。结果表明，关于掠夺性出版的文献是新的，但增长迅速，自 2016 年以来发表的研究占 88.6%。只有 37.3% 报告了实证研究，其中大部分是统计检验较弱的定量研究。医学期刊发表的文章最多。我们得出的结论是，关于掠夺性出版的学术研究处于发展的早期阶段，而且它在期刊、领域和研究背景中的分布很少。令人惊讶的是，在领先的高等教育期刊上没有发现任何研究，而这项研究揭示了一个仍在发展中的研究领域。
