Nature Examines High Counts of Corresponding Authors in China

A recent article published in Nature investigates the prevalence of multiple corresponding authors in Chinese research papers. The report, published online on June 4, 2026, is titled “What’s behind China’s historically high counts of corresponding authors?” and is identified by the digital object identifier doi:10.1038/d41586-026-01623-4.

The analysis focuses on a specific five-year window to highlight a significant trend in the region's scientific output. From 2016 to 2020, almost one-third of papers by authors in China had multiple corresponding authors. This statistic points to a notable practice regarding how authorship credit and responsibilities were assigned during this period.

However, the findings suggest that this pattern may be evolving. The source indicates that policy reforms are expected to have dampened the trend. This implies that regulatory changes implemented after the study period have likely influenced the frequency of multiple corresponding authors, potentially altering the authorship landscape for future publications.
