Nanjing University presents a globally balanced scientific integrity profile, with an overall risk score of -0.002 that aligns closely with the international average. The institution demonstrates significant strengths in publication ethics, particularly with very low risk in redundant publications and output in institutional journals, indicating a robust commitment to external validation and impactful research. However, this solid foundation is contrasted by medium-risk vulnerabilities in the Rate of Multiple Affiliations and the Rate of Hyperprolific Authors, which exceed national averages and require strategic attention. These findings are particularly relevant given the university's outstanding performance in several key disciplines, as evidenced by its SCImago Institutions Rankings, including top-tier global positions in Environmental Science, Earth and Planetary Sciences, Chemistry, and Physics and Astronomy. While the specific institutional mission was not provided, any commitment to academic excellence and social responsibility is inherently threatened by practices that could dilute authorial accountability or artificially inflate institutional credit. To secure its reputation as a world-class research institution, it is recommended that Nanjing University leverage its clear operational strengths to develop targeted governance policies that address authorship and affiliation practices, thereby ensuring its research impact is both authentic and sustainable.
The institution's Z-score of 0.773 for this indicator shows a moderate deviation from the national Z-score of -0.062. This suggests that the university exhibits a greater sensitivity to risk factors related to affiliation practices than its national peers. While multiple affiliations are often a legitimate result of researcher mobility or partnerships, the observed rate at Nanjing University is high enough to warrant a review. A disproportionately high rate can signal strategic attempts to inflate institutional credit or “affiliation shopping,” and this moderate alert level calls for an internal assessment to ensure all affiliations are transparent and reflect substantive collaboration.
With a Z-score of -0.043, the institution's performance is in close alignment with the national average of -0.050, indicating a level of risk that is statistically normal for its context. Retractions are complex events, and the current rate does not suggest a systemic failure in pre-publication quality control. Instead, it reflects a standard operational dynamic where occasional corrections are part of a healthy scientific process, demonstrating a responsible approach to post-publication supervision that is consistent with national integrity standards.
Nanjing University demonstrates notable institutional resilience in this area, with a low-risk Z-score of -0.180, which contrasts favorably with the medium-risk national Z-score of 0.045. This suggests that the university's internal control mechanisms are effectively mitigating a systemic risk prevalent in the country. A certain level of self-citation is natural, but the institution successfully avoids the 'echo chambers' that can lead to endogamous impact inflation. This low rate indicates that the university's academic influence is validated by the global community, not just by internal dynamics, reflecting strong external engagement.
The institution maintains a prudent profile with a Z-score of -0.280, which is significantly lower than the national average of -0.024. This indicates that the university manages its publication processes with more rigor than the national standard. A low rate of publication in journals that fail to meet international ethical or quality standards demonstrates effective due diligence in selecting dissemination channels. This careful approach protects the institution from severe reputational risks and shows a commitment to channeling research into credible and sustainable venues, avoiding predatory or low-quality practices.
The university's Z-score of -0.042, while in the low-risk category, points to an incipient vulnerability when compared to the national Z-score of -0.721. Although the overall risk is low, the institution shows signals that warrant review before they escalate. In many fields, extensive author lists are legitimate, but a rate higher than the national baseline serves as a signal to ensure that this pattern is driven by necessary massive collaboration. It is crucial to distinguish these cases from potential 'honorary' or political authorship practices that can dilute individual accountability and transparency.
A slight divergence is noted in this indicator, with the institution's Z-score at -0.711 compared to the country's very low-risk score of -0.809. This indicates the emergence of minor risk signals that are not as prevalent in the rest of the country. While it is common for institutions to rely on external partners for impact, this small gap suggests a need to monitor whether the university's scientific prestige is being built on its own structural capacity. It invites reflection on ensuring that excellence metrics result from genuine internal intellectual leadership rather than solely from strategic positioning in collaborations.
The institution shows high exposure in this area, with a Z-score of 0.921 that is considerably higher than the national average of 0.425, even though both fall within the medium-risk category. This indicates that the university is more prone to alert signals related to extreme productivity than its peers. While high output can reflect leadership, extreme individual volumes often challenge the limits of meaningful intellectual contribution. This elevated indicator warns of potential imbalances between quantity and quality, pointing to risks such as coercive authorship or the assignment of authorship without real participation—dynamics that prioritize metrics over the integrity of the scientific record.
The university's performance in this area is exemplary, with a very low-risk Z-score of -0.268, which is well below the low-risk national average of -0.010. This low-profile consistency demonstrates an absence of risk signals and aligns with the highest national standards. By avoiding excessive dependence on in-house journals, the institution mitigates potential conflicts of interest and the risk of academic endogamy. This practice ensures that its scientific production undergoes independent external peer review, enhancing its global visibility and confirming its commitment to competitive, merit-based validation.
Nanjing University exhibits total operational silence for this indicator, with a Z-score of -0.577 that signals an absence of risk even below the very low national average of -0.515. This outstanding result points to a strong institutional culture that values substantive contributions over artificially inflated productivity. It indicates that researchers are not engaging in 'salami slicing'—the practice of dividing a coherent study into minimal publishable units. This commitment to publishing complete and significant work strengthens the scientific record and reflects the highest standards of research ethics.
