Nanjing University of Chinese Medicine

EXECUTIVE SUMMARY AND STRATEGIC VISION

Nanjing University of Chinese Medicine presents a balanced and robust scientific integrity profile, with an overall risk score of -0.036 that indicates a performance closely aligned with global standards. The institution demonstrates exceptional strengths in areas of internal control and external validation, evidenced by very low risk levels in Institutional Self-Citation, Rate of Redundant Output, and Output in Institutional Journals. These results suggest a culture that prioritizes global engagement and substantive research over insular or fragmented publication strategies. However, areas requiring strategic attention have been identified, specifically a medium risk in the Rate of Retracted Output and the Rate of Output in Discontinued Journals. According to SCImago Institutions Rankings data, the university holds a world-class reputation in key thematic areas, most notably in Pharmacology, Toxicology and Pharmaceutics (ranked 30th globally), as well as in Medicine, Biochemistry, and Physics. The identified integrity risks, particularly those related to retractions and questionable publication venues, could potentially undermine the credibility and pursuit of excellence in these high-impact fields. Upholding the highest standards of scientific integrity is paramount to fulfilling the social responsibility inherent in medical and pharmaceutical research. Therefore, it is recommended that the institution focuses on reinforcing pre-publication quality control mechanisms and enhancing researcher literacy on selecting high-quality journals to safeguard and amplify its distinguished international standing.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution exhibits a Z-score of -0.654, which is lower than the national average of -0.062. This indicates a prudent and well-managed approach to academic collaboration. The university's practices appear more rigorous than the national standard, suggesting that its policies effectively ensure affiliations are the result of legitimate researcher mobility and genuine partnerships. This controlled rate minimizes the risk of strategic "affiliation shopping" and reinforces the transparency of its institutional credit attribution.

Rate of Retracted Output

With a Z-score of 0.230, the institution shows a medium risk level, which represents a moderate deviation from the low-risk national average of -0.050. This discrepancy suggests the university is more sensitive to factors leading to retractions than its peers. While some retractions can signify responsible supervision and the correction of honest errors, a rate significantly higher than the national context serves as an alert. It points to a potential vulnerability in the institution's integrity culture, indicating that pre-publication quality control mechanisms may be failing more frequently than expected and warrant an immediate qualitative verification by management to address any recurring methodological or ethical issues.

Rate of Institutional Self-Citation

The institution demonstrates an exceptionally low Z-score of -1.004, positioning it as a case of preventive isolation from the medium-risk dynamics observed at the national level (Z-score: 0.045). This result is a significant strength, indicating that the university does not replicate the risk of scientific isolation common in its environment. Such a low rate of self-citation signals a strong outward-looking research culture that avoids "echo chambers" and seeks validation from the global scientific community. This practice ensures that the institution's academic influence is driven by broad external recognition rather than being inflated by internal dynamics.

Rate of Output in Discontinued Journals

The institution's Z-score of 1.137 reflects a medium risk, a notable deviation from the low-risk national average of -0.024. This suggests the university is more exposed to the risk of publishing in low-quality or predatory venues than its national counterparts. This pattern constitutes a critical alert regarding the due diligence applied in selecting dissemination channels. A high proportion of output in such journals indicates that a significant part of its research is channeled through media lacking international ethical or quality standards, exposing the institution to severe reputational risks and signaling an urgent need for enhanced information literacy among its researchers.

Rate of Hyper-Authored Output

The institution's Z-score of -0.665 is slightly higher than the national average of -0.721, though both remain in the low-risk category. This subtle difference points to an incipient vulnerability that warrants monitoring. While its authorship patterns are largely normal, the slight increase compared to the national baseline serves as a signal to ensure that practices remain transparent. It is important to continue distinguishing between necessary massive collaboration, which is legitimate in some fields, and any potential for "honorary" or political authorship practices that could dilute individual accountability.

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

With a Z-score of -0.629, the institution shows a slight divergence from the national context, where the risk is very low (Z-score: -0.809). This indicates the presence of a minor risk signal that is not apparent in the rest of the country. The data suggests that the university's scientific prestige may be slightly more dependent on external collaborations where it does not exercise intellectual leadership. While partnering is common, this gap invites reflection on strengthening internal capacity to ensure that its high-impact metrics are a result of its own structural excellence and not primarily driven by an exogenous, dependent positioning.

Rate of Hyperprolific Authors

The institution maintains a low-risk Z-score of -0.780, demonstrating significant institutional resilience against a trend more prevalent at the national level, which has a medium-risk score of 0.425. This indicates that the university's control mechanisms are effective in mitigating the systemic risks of hyper-prolificacy seen elsewhere in the country. By preventing extreme individual publication volumes, the institution fosters a research environment that likely prioritizes quality and meaningful intellectual contribution over sheer quantity, thereby avoiding the risks of coercive authorship or the assignment of credit without real participation.

Rate of Output in Institutional Journals

The institution's Z-score of -0.268 is in the very low-risk category, showing low-profile consistency with the low-risk national standard (Z-score: -0.010). The absence of risk signals in this area aligns perfectly with the national environment. This commitment to publishing in external venues is a positive indicator, as it avoids the conflicts of interest and academic endogamy that can arise from over-reliance on in-house journals. This practice ensures that its scientific production undergoes independent external peer review, enhancing its global visibility and competitive validation.

Rate of Redundant Output

With a Z-score of -0.950, the institution shows a total operational silence regarding this risk, performing even better than the very low-risk national average of -0.515. This is an outstanding result, demonstrating an absence of risk signals that is even below the national baseline. It strongly suggests a research culture that values the publication of coherent, significant studies over the practice of "salami slicing." This commitment to avoiding data fragmentation not only upholds the integrity of the scientific record but also prevents the artificial inflation of productivity metrics.
