International collaboration is sometimes encouraged in the belief that it generates higher quality research or is more capable of addressing societal problems. Nevertheless, while there is evidence that the journal articles of international teams tend to be more cited than average, perhaps from increased international audiences, there is no science‐wide direct academic evidence of a connection between international collaboration and research quality. This article empirically investigates the connection between international collaboration and research quality for the first time, with 148,977 UK‐based journal articles with post publication expert review scores from the 2021 Research Excellence Framework (REF). Using an ordinal regression model controlling for collaboration, international partners increased the odds of higher quality scores in 27 out of 34 Units of Assessment (UoAs) and all Main Panels. The results therefore give the first large scale evidence of the fields in which international co‐authorship for articles is usually apparently beneficial. At the country level, the results suggests that UK collaboration with other high research‐expenditure economies generates higher quality research, even when the countries produce lower citation impact journal articles than the United Kingdom. Worryingly, collaborations with lower research‐expenditure economies tend to be judged lower quality, possibly through misunderstanding Global South research goals.

哪些国际合作作者发表的期刊文章质量更高？

有时鼓励国际合作，因为人们相信国际合作可以产生更高质量的研究或更能够解决社会问题。尽管如此，虽然有证据表明，国际团队的期刊文章被引用的次数往往高于平均水平，可能是来自越来越多的国际读者，但没有科学范围内的直接学术证据表明国际合作与研究质量之间存在联系。本文首次对国际合作与研究质量之间的联系进行了实证研究，其中包括 148,977 篇英国期刊文章，以及来自 2021 年卓越研究框架 (REF) 的发表后专家评审分数。使用控制协作的序数回归模型，国际合作伙伴提高了 34 个评估单元 (UoAs) 和所有主要小组中的 27 个获得更高质量分数的几率。因此，这些结果首次大规模证明了国际合作撰写文章通常明显有益的领域。在国家层面，结果表明，英国与其他高研究支出经济体的合作产生了更高质量的研究，即使这些国家发表的期刊文章的引用影响力低于英国。令人担忧的是，与研究支出较低的经济体的合作往往被认为质量较低，这可能是由于误解了全球南方的研究目标。
