Xiamen University

EXECUTIVE SUMMARY AND STRATEGIC VISION

Xiamen University demonstrates a robust scientific integrity profile, with an overall risk score of -0.263 indicating a performance well within the parameters of responsible research conduct. The institution's primary strengths lie in its exceptionally low rates of retracted output, redundant publications (salami slicing), and publication in institutional journals, signaling strong quality control and a commitment to external validation. The only notable vulnerability is a medium-risk signal related to hyperprolific authors, which suggests a potential imbalance between publication volume and research quality that warrants attention. This solid integrity foundation supports the university's outstanding academic achievements, as evidenced by its SCImago Institutions Rankings, which place it in the global elite in areas such as Economics, Econometrics and Finance (Top 10), Business, Management and Accounting (Top 60), Energy (Top 60), and Chemistry (Top 70). The university's mission to "Pursue Excellence and Strive for Perfection" is largely reflected in these low-risk indicators. However, the presence of hyperprolificacy could challenge the ideal of "perfection," as it prioritizes quantity in a way that may conflict with deep, impactful research. By addressing this isolated issue, Xiamen University can further align its operational practices with its aspirational mission, solidifying its reputation as a global leader in both academic excellence and scientific integrity.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

With a Z-score of -0.213, the university demonstrates a more controlled approach to multiple affiliations compared to the national average of -0.062. This prudent profile suggests that the institution manages its collaborative attributions with greater rigor than the national standard. While multiple affiliations can be legitimate, disproportionately high rates can signal strategic attempts to inflate institutional credit. The university's controlled rate indicates a healthy and transparent approach, minimizing ambiguity in research ownership and contribution.

Rate of Retracted Output

The institution's performance in this area is exemplary, with a Z-score of -0.381, which is significantly lower than the already low national score of -0.050. This near-absence of risk signals is consistent with a secure national environment and points to highly effective internal governance. A high rate of retractions can suggest systemic failures in quality control prior to publication. In contrast, the university's exceptionally low rate indicates that its pre-publication review and methodological supervision mechanisms are robust, safeguarding its scientific record and reputation.

Rate of Institutional Self-Citation

Xiamen University shows remarkable resilience against national trends, posting a low Z-score of -0.463 in a country where this indicator is a medium-level concern (country Z-score of 0.045). This demonstrates that the institution's control mechanisms are effectively mitigating a systemic risk present in its environment. Disproportionately high rates of self-citation can signal scientific isolation or 'echo chambers.' The university's low rate, however, suggests its academic influence is validated by the broader international community, avoiding endogamous impact inflation and reinforcing the global relevance of its work.

Rate of Output in Discontinued Journals

The institution exhibits a more prudent profile than its national peers, with a Z-score of -0.194 compared to the country's average of -0.024. This indicates a more rigorous due diligence process in selecting publication channels. A high proportion of output in discontinued journals is a critical alert for reputational risk, suggesting that research is being channeled through media that fail to meet international ethical or quality standards. The university's careful management in this area protects its resources and scholarly reputation from association with 'predatory' practices.

Rate of Hyper-Authored Output

Although the institution's rate of hyper-authored output is low (Z-score -0.505), it is slightly higher than the national average (Z-score -0.721), signaling an incipient vulnerability. While extensive author lists are legitimate in 'Big Science' collaborations, a rising trend outside these contexts can indicate author list inflation, which dilutes individual accountability. This subtle signal warrants review to ensure that authorship practices remain transparent and that all listed contributors have made meaningful intellectual contributions, thereby preventing the normalization of 'honorary' authorship.

Gap between Impact of total output and the impact of output with leadership

The university shows a slight divergence from the national baseline, with a Z-score of -0.578 in an area where risk signals are virtually non-existent for the country (-0.809). This indicates the emergence of a minor signal of risk activity not seen elsewhere in the country. A wide gap in this indicator suggests that an institution's scientific prestige may be dependent on external partners rather than its own structural capacity. While the current level is not alarming, it points to an opportunity to strengthen intellectual leadership in collaborations to ensure its reputation for excellence is fully sustained by its internal research capabilities.

Rate of Hyperprolific Authors

This indicator presents a point of high exposure for the institution, with a Z-score of 0.504 that is notably higher than the national average of 0.425. The university appears more prone to this risk than its peers. Extreme individual publication volumes challenge the limits of human capacity for meaningful intellectual contribution and can point to an imbalance between quantity and quality. This elevated rate serves as an alert for potential risks such as coercive authorship, data fragmentation, or authorship assignment without real participation—dynamics that prioritize metrics over the integrity of the scientific record and require management review.

Rate of Output in Institutional Journals

The university's practices show a strong alignment with a low-risk national environment, with its Z-score of -0.268 indicating a significantly lower reliance on its own journals than the country average of -0.010. This absence of risk signals demonstrates a firm commitment to independent, external peer review. Excessive dependence on in-house journals can create conflicts of interest and academic endogamy. By avoiding this, the institution ensures its research is validated through competitive, global channels, thereby enhancing its credibility and international visibility.

Rate of Redundant Output

In this domain, the institution demonstrates total operational silence, with a Z-score of -0.702 that is even lower than the secure national average of -0.515. This complete absence of risk signals is exemplary. A high rate of redundant output, or 'salami slicing,' indicates the practice of fragmenting a single study into multiple publications to artificially inflate productivity, which distorts the scientific evidence base. The university's outstanding result reflects a culture that prioritizes the publication of complete, coherent studies, valuing significant new knowledge over sheer volume.
