Persistent Hierarchy in Contemporary International Collaboration

Abstract: Science is increasingly global, with international collaboration playing a crucial role in advancing scientific development and knowledge exchange across borders. However, the processes that regulate how scientific labor is distributed among countries remain underexplored, leading to challenges in ensuring both effective collaboration and equitable participation across diverse scientific communities. Here, we leverage three million internationally coauthored publications produced by countries worldwide to examine the division of scientific labor in international collaboration, identify the factors that shape this distribution, and assess its broader consequences. Our findings uncover a persistent hierarchical structure in international collaboration, with researchers from scientifically advanced countries tend to occupy leading roles, while those from less-developed countries are often relegated to supportive roles, even after controlling for various influential factors. This hierarchy is also reflected in the research content, as countries with lower scientific capacity tend to participate in international collaborations that deviate from their domestic science. By analyzing the labor division within international collaborations, we demonstrate that researchers from less-developed countries face systematic disadvantages, which not only limit their contributions to the global scientific community but also prevent them from fully benefiting from international collaborations.

• The paper identifies entrenched hierarchies in global scientific collaborations, with advanced nations dominating prestigious authorship roles.
• The paper employs fixed-effects regression and a dataset of 3 million publications to demonstrate the critical influence of nationality on authorship order.
• The paper uncovers task specialization differences using the CRediT taxonomy, showing advanced researchers are overrepresented in strategic roles.

Persistent Hierarchy in Contemporary International Collaboration

The study "Persistent Hierarchy in Contemporary International Collaboration" investigates the entrenched hierarchies within global scientific collaborations, revealing significant disparities in the roles assumed by researchers from different countries. The analysis draws on a vast dataset of three million internationally coauthored publications across 201 nations to scrutinize authorship order, a proxy for the division of scientific labor, and to uncover systematic disadvantages faced by researchers from less-developed countries.

Key Findings

International scientific collaboration is marked by a hierarchical structure, substantially influenced by a country's scientific capacity. Researchers from scientifically advanced countries typically occupy prestigious roles, such as last authorship—often synonymous with leadership and supervision—while those from non-advanced countries are more likely to assume supportive positions, such as middle authorship. The results hold even when adjusting for variables such as funding, gender, and scientific capacity.

• Authorship Trends: Researchers from scientifically proficient countries have noticeably increased their participation and are more likely to secure first authorship positions, suggesting their involvement in the core research activities. However, non-advanced countries continue to be underrepresented in first and last authorship roles.
• Regression Analysis: The fixed-effects regression models confirm that nationality plays a critical role in determining authorship order, emphasizing the systematic underrepresentation of non-advanced country researchers in leading roles despite controlling for other factors.
• Task Specialization: The analysis of a subset dataset from PLOS journals using CRediT taxonomy indicates specific task delineations, with researchers from advanced countries often overrepresented in strategic roles, including conceptualization and supervision, while others are relegated to supportive functions like data curation and software development.

Implications

The results provide evidence of a persistent power imbalance in international collaborations, echoing neo-colonial patterns where the global research agenda is primarily driven by scientifically advanced countries. This inequity influences the scientific topics and priorities, as researchers from less-developed regions work on subjects divergent from their domestic research when in international settings, potentially sidelining local scientific needs.

These findings also highlight the challenges for researchers from non-advanced countries in accruing scientific capital, as authorship remains a primary metric for professional advancement. The systemic nature of these disparities suggests a need for reevaluation and restructuring of international scientific collaborations to promote equity and inclusivity, allowing for diverse contributions and perspectives.

Future Directions

In light of these insights, further research is warranted to explore methods of establishing more equitable collaboration frameworks. The integration of transparent authorship practices and equitable resource distribution could mitigate disparities. Additionally, fostering local scientific capacity-building initiatives and promoting policies that support diverse scientific leadership are crucial for reducing the global scientific gap.

The study underscores the importance of recognizing and addressing the nuanced dynamics in international collaborations, as the scientific community continues to tackle increasingly complex global challenges. A shift towards more inclusive practices may not only enhance scientific output but also align research agendas with local and global societal needs.
