Nanjing University of Posts and Telecommunications

EXECUTIVE SUMMARY AND STRATEGIC VISION

Nanjing University of Posts and Telecommunications presents a balanced scientific integrity profile, with an overall risk score of -0.046 that aligns closely with the global baseline. The institution demonstrates significant strengths in core areas of research quality and ethics, evidenced by very low risk levels in Retracted Output, Output in Institutional Journals, and Redundant Output. These results point to robust pre-publication review processes, a commitment to external validation, and a culture that prioritizes substantive contributions over volume. However, areas requiring strategic attention include a higher-than-average incidence of Multiple Affiliations and Hyperprolific Authors, a notable dependency on external collaborations for impact (Gap between Impact of total output and the impact of output with leadership), and a tendency toward Institutional Self-Citation. These medium-risk indicators suggest a need to reinforce policies that ensure authorship is transparent, impact is sustainable, and academic discourse remains open to external validation. These findings are particularly relevant given the institution's world-class standing in key disciplines, as shown by SCImago Institutions Rankings data, including Computer Science (ranked 83rd globally), Mathematics (94th), and Engineering (160th). While a specific mission statement was not available for analysis, any institutional goal centered on achieving scientific excellence and social impact is fundamentally supported by high integrity. The identified vulnerabilities, if left unaddressed, could undermine the credibility of its outstanding research and challenge the long-term sustainability of its leadership in these strategic fields. A proactive approach to monitoring these specific indicators will be crucial to solidifying its reputation and ensuring its research practices are as robust as its scientific output.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution presents a Z-score of 0.296, which contrasts with the national average of -0.062. This moderate deviation indicates that the university shows 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 higher rate here suggests a need for review. It is important to ensure that this pattern reflects genuine, substantive collaborations rather than strategic attempts to inflate institutional credit or "affiliation shopping," a practice that could dilute the university's distinct academic identity.

Rate of Retracted Output

With a Z-score of -0.418, the institution demonstrates an exceptionally low rate of retracted publications, performing even better than the low-risk national average of -0.050. This low-profile consistency signals the presence of highly effective quality control mechanisms. The absence of risk signals in this critical area suggests that the university's supervision and pre-publication review processes are robust and function as a systemic safeguard against methodological errors or potential malpractice, reflecting a strong institutional culture of integrity that aligns with and exceeds the national standard.

Rate of Institutional Self-Citation

The institution's Z-score for self-citation is 0.149, while the national average is 0.045. Although both fall within a medium-risk band, the university's rate is notably higher, indicating greater exposure to this particular risk. A certain level of self-citation is natural, reflecting the continuity of research lines. However, this disproportionately high rate warns of potential scientific isolation or 'echo chambers' where work is validated internally without sufficient external scrutiny. This dynamic suggests that the institution's academic influence may be at risk of being oversized by internal dynamics rather than by broader recognition from the global scientific community.

Rate of Output in Discontinued Journals

The institution's Z-score of -0.028 is nearly identical to the national average of -0.024, demonstrating statistical normality in this area. This alignment indicates that the risk level associated with publishing in discontinued journals is as expected for its context and size. This result suggests that the institution's researchers exercise a standard level of due diligence in selecting dissemination channels, effectively avoiding systemic exposure to predatory or low-quality publishing practices that could carry severe reputational risks.

Rate of Hyper-Authored Output

With a Z-score of -1.017, the institution displays a prudent profile, showing a lower incidence of hyper-authored publications compared to the national average of -0.721. This suggests that the university manages its authorship processes with more rigor than the national standard. This result is a positive signal that the institution effectively distinguishes between necessary massive collaboration, common in 'Big Science,' and potentially problematic practices like 'honorary' or political authorship, thereby promoting greater individual accountability and transparency in its research contributions.

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

The institution's Z-score of 0.033 creates a monitoring alert, as it represents an unusual risk level when compared to the national standard, which sits at a very low -0.809. This significant divergence suggests that the university's scientific prestige may be highly dependent on external partners rather than being structurally generated from within. A wide positive gap, where overall impact is high but the impact of institution-led research is low, signals a sustainability risk. It invites reflection on whether the institution's excellence metrics result from its own core scientific capacity or from strategic positioning in collaborations where it does not exercise primary intellectual leadership.

Rate of Hyperprolific Authors

The institution's Z-score of 1.489 is significantly higher than the national average of 0.425, even though both are categorized as medium risk. This indicates that the university has a high exposure to this risk and is more prone to showing alert signals than its environment. While high productivity can reflect leadership, extreme individual publication volumes challenge the limits of meaningful intellectual contribution. This elevated indicator alerts to 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.

Rate of Output in Institutional Journals

The institution's Z-score of -0.268 is in the very low-risk category, well below the low-risk national average of -0.010. This low-profile consistency demonstrates a strong commitment to seeking external, independent validation for its research. By avoiding excessive dependence on in-house journals, the university mitigates the conflicts of interest that arise when an institution acts as both judge and party. This practice enhances the global visibility and credibility of its scientific production, steering clear of academic endogamy and the risk of using internal channels as 'fast tracks' to inflate publication records without standard competitive review.

Rate of Redundant Output

With a Z-score of -0.505, the institution is in a state of integrity synchrony with the national environment, which has a nearly identical score of -0.515. This total alignment in a very low-risk environment indicates the absence of signals related to data fragmentation or 'salami slicing.' It reflects a healthy research culture where the focus is on producing coherent, significant studies rather than artificially inflating productivity by dividing a single body of work into minimal publishable units. This practice upholds the quality of the scientific record and respects the resources of the peer-review system.
