Nanjing Agricultural University

EXECUTIVE SUMMARY AND STRATEGIC VISION

Nanjing Agricultural University presents a strong overall profile of scientific integrity, with a consolidated risk score of -0.372 that indicates robust institutional governance. This performance is anchored in exceptional strengths, particularly in the areas of research autonomy, quality control, and responsible publication practices. The university's global leadership is evident in its SCImago Institutions Rankings, where it holds world-class positions in key disciplines such as Agricultural and Biological Sciences (ranked 7th globally) and Veterinary (19th globally). However, two areas require strategic attention: the Rate of Multiple Affiliations and the Rate of Institutional Self-Citation, both of which register at a medium-risk level and deviate from national norms. These vulnerabilities could subtly undermine the university's mission to "improve the quality of education" and "contribute back to society," as they may suggest a focus on internal validation or metric optimization over externally recognized, transparent impact. By addressing these specific points of friction, the university can further solidify its reputation for excellence and ensure its significant contributions are built upon an unshakeable foundation of scientific integrity.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution's Z-score of 0.408 for this indicator represents a moderate deviation from the national standard, which sits at a low-risk Z-score of -0.062. This suggests the university is more exposed to practices that can inflate this metric compared to its national peers. While multiple affiliations are often a legitimate result of researcher mobility or partnerships, disproportionately high rates can signal strategic attempts to inflate institutional credit or “affiliation shopping”. Given the divergence from the national trend, a review of affiliation policies is recommended to ensure they consistently reflect genuine, substantive collaboration and uphold the transparency of scholarly contributions.

Rate of Retracted Output

With an exceptionally low Z-score of -0.428, the institution demonstrates outstanding performance in this area, surpassing the already low-risk national average of -0.050. This result indicates a state of low-profile consistency, where the absence of risk signals aligns perfectly with a secure national environment. It strongly suggests that the university's quality control mechanisms prior to publication are not only effective but exemplary. This is a hallmark of a mature integrity culture, where rigorous supervision and sound methodology minimize the occurrence of errors, thereby reinforcing the trustworthiness of the institution's scientific output.

Rate of Institutional Self-Citation

The university's Z-score of 0.134 is in the medium-risk category, numerically higher than the national average of 0.045, which is also at a medium level. This indicates a high exposure to this risk, suggesting the institution is more prone than its peers to developing patterns of academic insularity. A certain level of self-citation is natural and reflects the continuity of established research lines. However, the observed rate warns of a potential 'echo chamber' where the institution's work may not be receiving sufficient external scrutiny, creating a risk of endogamous impact inflation. To counteract this, fostering broader engagement with the global scientific community is crucial to ensure academic influence is driven by external recognition rather than internal dynamics.

Rate of Output in Discontinued Journals

The institution exhibits a very low Z-score of -0.464, a figure that is significantly stronger than the low-risk national average of -0.024. This demonstrates a consistent and commendable approach to selecting publication venues, aligning with national standards of good practice. This excellent performance is a critical indicator of due diligence, showing that researchers are effectively avoiding dissemination channels that fail to meet international ethical or quality standards. Such vigilance protects the institution from severe reputational risks and ensures that its resources are invested in credible and impactful scientific communication.

Rate of Hyper-Authored Output

The institution maintains a prudent profile with a low Z-score of -0.840, which is more controlled than the national average of -0.721. This suggests that the university manages its authorship attribution processes with more rigor than the national standard. This performance indicates a healthy ability to distinguish between necessary massive collaboration, which is common in some fields, and the risk of author list inflation. By maintaining clear standards, the institution effectively discourages 'honorary' authorship, thereby reinforcing individual accountability and the transparency of each researcher's contribution.

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

With an outstanding Z-score of -1.312, the institution shows a near-total absence of risk in this area, performing significantly better than the strong national average of -0.809. This signals a state of total operational silence on this indicator, which is a powerful sign of scientific autonomy and sustainability. It demonstrates that the institution's scientific prestige is not dependent on external partners but is structurally generated by its own internal capacity and intellectual leadership. This is a key characteristic of a mature and self-reliant research powerhouse, capable of driving its own high-impact agenda.

Rate of Hyperprolific Authors

The university displays strong institutional resilience, with a low-risk Z-score of -0.122 in contrast to the medium-risk national level of 0.425. This indicates that internal control mechanisms are successfully mitigating a systemic risk that is more prevalent in the wider national environment. While high productivity can be a sign of leadership, extreme publication volumes can challenge the limits of meaningful intellectual contribution. The institution's controlled profile suggests a healthy balance between quantity and quality, effectively preventing potential issues such as coercive authorship or the prioritization of metrics over the integrity of the scientific record.

Rate of Output in Institutional Journals

The institution's Z-score of -0.268 is in the very low-risk category, outperforming the low-risk national average of -0.010. This result demonstrates a consistent alignment with best practices, reflecting a clear institutional preference for validation through external, independent peer review. By minimizing its reliance on in-house journals, the university effectively avoids potential conflicts of interest and the risk of academic endogamy. This strategy enhances the global visibility and credibility of its research, ensuring its work is judged and accepted on competitive international platforms.

Rate of Redundant Output

With an exceptionally low Z-score of -1.034, the institution demonstrates a near-total absence of risk signals for redundant publication, performing markedly better than the already very low national average of -0.515. This is a clear indicator of a culture that values substantive scientific contributions over inflated publication counts. It shows a strong commitment to publishing complete and coherent studies, avoiding the practice of data fragmentation or 'salami slicing.' This approach not only upholds the integrity of the scientific evidence base but also shows profound respect for the academic review system.
