China's Rising Trend of Multiple Corresponding Authors Reshapes Academic Publishing
China's research community has seen a marked increase in the practice of listing multiple corresponding authors on academic papers, a development that reflects broader shifts in evaluation systems and collaborative dynamics within the country's higher-education and research institutions. This trend, documented through large-scale bibliometric analyses, highlights how incentive structures tied to promotions, funding, and institutional rankings influence authorship practices across universities and research centers.
Understanding Corresponding Authorship in Context
Corresponding authorship traditionally designates the researcher responsible for communication with journals, handling revisions, and often serving as the primary point of contact for inquiries about the work. In many global contexts, this role falls to a single senior investigator. However, in China, the role has evolved to accommodate multiple individuals, frequently within the same institution, as a response to performance-based metrics that reward such positions in hiring, tenure, and resource allocation decisions at universities under the oversight of the Ministry of Education and the Ministry of Science and Technology.
The practice allows several researchers to share the visibility and credit associated with the role, particularly in experimental fields where teams from the same laboratory or department collaborate closely. This intra-institutional pattern accounts for the majority of cases, underscoring how domestic evaluation frameworks shape publication strategies more than international collaborations in many instances.
Scale and Growth of the Phenomenon
Bibliometric examinations of nearly 1.75 million articles indexed in the Web of Science from 2016 to 2020 reveal that researchers affiliated with Chinese institutions were substantially more likely to employ multiple corresponding authors than their counterparts elsewhere. The share of such papers rose steadily, reaching approximately 30 percent by 2020, compared with a global average that remained below 9 percent over the same period. This represents a significant departure from earlier years, when the figure stood around 22 percent in 2016.
The disparity is especially pronounced in disciplines involving laboratory work and data-intensive experiments, where team contributions are common. Prolific authors, often occupying the last position in the author list, increasingly appear as corresponding authors, signaling seniority and leadership within research groups at institutions such as Tsinghua University, Peking University, and the Chinese Academy of Sciences.
Drivers Rooted in Evaluation and Incentive Systems
China's higher-education sector has long emphasized quantitative outputs for career advancement. First and corresponding author positions have carried particular weight in assessments for faculty appointments, promotions, and access to national talent programs. This emphasis encouraged strategic authorship arrangements, including the listing of multiple corresponding authors to distribute credit among team members while meeting institutional benchmarks.
Reforms introduced around 2020 by the Ministry of Science and Technology and the Ministry of Education aimed to reduce reliance on journal impact factors and Science Citation Index metrics for evaluations and funding decisions. These changes sought to curb practices perceived as inflating publication counts without corresponding gains in research quality. Early indications suggest the reforms may moderate the growth of multiple corresponding authorship, though the practice remains embedded in collaborative norms at many universities and research institutes.

Implications for Research Integrity and Collaboration
The proliferation of multiple corresponding authors raises questions about accountability and the clarity of contributions. While the arrangement can reflect genuine shared leadership in large teams, it also complicates traditional notions of responsibility for the published work. In experimental fields, where 83 percent of Chinese cases involve authors from the same institution, the pattern often aligns with internal hierarchies rather than cross-border partnerships.
International observers note that similar, though less pronounced, increases in multiple corresponding authorship appear in other Asian contexts, pointing to regional cultural and policy influences. For Chinese universities seeking to strengthen global standing, balancing these domestic practices with transparent authorship guidelines has become an ongoing priority.
Perspectives from Stakeholders in Higher Education
University administrators at leading Chinese institutions face the challenge of aligning evaluation criteria with international standards while supporting productive research teams. Many have begun experimenting with revised promotion frameworks that consider a broader range of contributions beyond authorship positions. Researchers, particularly early-career academics and doctoral candidates, report navigating these norms carefully, recognizing that corresponding author status can influence visibility in competitive job markets both domestically and abroad.
PhD-track job seekers interested in positions at Chinese universities or collaborative projects often benefit from understanding these conventions, as they shape how contributions are recognized in hiring processes at institutions affiliated with national research priorities.
Comparative Context with Global Trends
While multiple corresponding authorship has increased worldwide, the scale in China stands out. Global averages have risen modestly, driven in part by larger collaborative teams and international projects. In contrast, China's figures reflect a combination of rapid research expansion, team-based laboratory cultures, and historically metric-driven evaluation systems at universities and research academies.
Analyses of authorship patterns across countries show that Asian nations, including China, exhibit higher rates than those in Europe or North America. This underscores the importance of context-specific policies when addressing authorship norms in higher-education settings.
Policy Responses and Institutional Adaptations
Following the 2020 policy announcements discouraging the sole use of impact factors for assessments, several universities and funding bodies adjusted their internal guidelines. Some introduced qualitative review components or limited the weight given to corresponding author counts. These adaptations aim to foster research environments where quality and innovation receive greater emphasis than quantitative authorship metrics.
National bodies continue to monitor trends, with expectations that the practice will stabilize or decline as new evaluation models take hold across the higher-education sector.

Future Outlook for Chinese Research Publishing
As China continues to expand its research output and deepen international collaborations, authorship practices are likely to evolve further. Greater emphasis on open science, transparent contribution statements, and diversified evaluation criteria could reduce reliance on multiple corresponding authors as a strategic tool. Institutions are increasingly exploring mentorship programs and training on responsible authorship to support emerging researchers.
For the global academic community, these developments offer insights into how national policies influence publishing behaviors and the ongoing conversation about fair credit allocation in team science.
Practical Considerations for Researchers and Administrators
Academics working with Chinese collaborators or seeking positions in the sector can benefit from clear communication about authorship expectations early in projects. Institutions may consider developing explicit guidelines that balance team recognition with individual accountability. Job seekers tracking opportunities through platforms focused on higher-education roles in China should remain attentive to evolving norms around authorship credit.
These adjustments support healthier research cultures while maintaining China's competitive edge in global scholarship.
