<p>Multiple corresponding authorships imply a higher level of commitment, which also implies a higher level of quality. In this study, we explore the relationship between the phenomenon of multiple corresponding authorships and citation counts. To do this, an empirical research is conducted, and Double Machine Learning models—a novel method—are used. Our results of the case study based on the field of “Chemistry &amp; Medicine” demonstrate that, when controlling for other variables, articles with multiple corresponding authors indeed tend to receive more citations than those with a single corresponding author. In addition, the citation advantage is more pronounced when multiple corresponding authors are from different institutions. However, an excessive number of corresponding authors may weaken the citation advantage. These findings remain robust as they still hold when incorporating interdisciplinarity as a control variable and using other methods (e.g., Propensity Score Matching).</p>
