Vietnam National University, Hanoi

EXECUTIVE SUMMARY AND STRATEGIC VISION

Vietnam National University, Hanoi, demonstrates a complex profile of scientific integrity, marked by areas of exceptional governance alongside specific, significant vulnerabilities. The institution's strengths are notable in its very low rates of Institutional Self-Citation, Redundant Output, and publication in its own journals, indicating a robust culture of external validation and a focus on substantive research that effectively isolates it from contrary national trends. However, these strengths are counterbalanced by a critical dependency on external collaborations for impact, a moderate incidence of retractions, and a higher-than-average rate of multiple affiliations. These risks could undermine the university's mission to produce "high quality human resources" and pioneer "advanced science," as true leadership requires not just participation but intellectual ownership. The university's strong national standing in key thematic areas such as Earth and Planetary Sciences (ranked 4th), Economics, Econometrics and Finance (ranked 5th), and Chemistry (ranked 7th), according to SCImago Institutions Rankings data, provides a solid foundation. To fully realize its pioneering role, VNU is encouraged to leverage its clear integrity strengths to address its strategic vulnerabilities, particularly by fostering internal research leadership to ensure its long-term scientific sovereignty and impact.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution presents a Z-score of 0.982, which represents a moderate deviation from the national average of -0.035. This suggests the university shows a greater sensitivity to risk factors in this area than its national peers. While multiple affiliations are often legitimate, the higher rate at this institution could signal strategic attempts to inflate institutional credit or "affiliation shopping." This divergence from the national standard warrants a review to ensure that affiliation policies are transparent and reflect genuine collaborative contributions rather than metric-driven incentives.

Rate of Retracted Output

The institution's Z-score of 0.756 is nearly identical to the national average of 0.749, indicating a systemic pattern. This alignment suggests that the risk level for retractions reflects shared practices or vulnerabilities common throughout the country's research ecosystem. A high Z-score in this indicator suggests that quality control mechanisms prior to publication may be failing systemically. Beyond individual cases of honest error, a rate significantly higher than the global average alerts to a vulnerability in the integrity culture, indicating possible recurring malpractice or a lack of methodological rigor that requires immediate qualitative verification by management.

Rate of Institutional Self-Citation

The institution exhibits a Z-score of -1.693, in stark contrast to the national average of 0.192. This demonstrates a case of preventive isolation, where the university successfully avoids the risk dynamics observed in its environment. A certain level of self-citation is natural, but the country's moderate rate suggests a tendency towards 'echo chambers.' The institution's very low score, however, is a clear strength, indicating that its work is validated by the broader scientific community and its academic influence is built on global recognition rather than endogamous internal dynamics.

Rate of Output in Discontinued Journals

With a Z-score of 1.026, the institution performs slightly better than the national average of 1.127, demonstrating differentiated management of a risk that is common in the country. Although both scores are in the medium-risk range, the university appears to moderate this issue more effectively than its peers. Nevertheless, a high proportion of publications in such journals remains a critical alert regarding due diligence. This Z-score indicates that a significant portion of scientific production is being channeled through media that may not meet international ethical or quality standards, exposing the institution to reputational risks and suggesting a need for enhanced information literacy.

Rate of Hyper-Authored Output

The institution's Z-score of -0.441, while low, is higher than the national average of -0.822, pointing to an incipient vulnerability. This suggests that while hyper-authorship is not a major issue, the university shows early signals that warrant review before they escalate. In disciplines outside of 'Big Science,' a high Z-score can indicate author list inflation, which dilutes individual accountability. This slight elevation compared to the national norm serves as a signal to ensure that authorship practices remain transparent and distinguish necessary massive collaboration from 'honorary' attributions.

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

The institution presents a Z-score of 3.294, a figure that represents a severe discrepancy when compared to the national average of -0.112. This atypical risk activity requires a deep integrity assessment, as it suggests the institution's scientific prestige is highly dependent and exogenous, not structural. The very wide positive gap—where global impact is high but the impact of research led by the institution itself is low—signals a critical sustainability risk. This invites urgent reflection on whether the university's excellence metrics result from its own internal capacity or from strategic positioning in collaborations where it does not exercise intellectual leadership.

Rate of Hyperprolific Authors

The institution's Z-score of -0.062 is higher than the national average of -0.501, signaling an incipient vulnerability. Although both values are in the low-risk category, the university shows slightly stronger signals of this activity, which warrant review before escalating. Extreme individual publication volumes can challenge the limits of meaningful intellectual contribution. This 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 scientific record integrity.

Rate of Output in Institutional Journals

The institution's Z-score of -0.268 is perfectly aligned with the national average of -0.268, demonstrating integrity synchrony. This total alignment with an environment of maximum scientific security is a significant strength. It shows that the university avoids the potential conflicts of interest and academic endogamy that can arise from excessive dependence on in-house journals. By favoring external, independent peer review, the institution ensures its scientific production undergoes standard competitive validation, enhancing its global visibility and credibility.

Rate of Redundant Output

With a Z-score of -0.622, the institution shows a clear preventive isolation from the national trend, where the average is 0.313. The university does not replicate the risk dynamics observed in its environment, marking a key area of strength. While the national context shows a medium risk of data fragmentation or 'salami slicing,' the institution's very low score indicates a strong commitment to publishing coherent, significant studies. This practice avoids artificially inflating productivity metrics and contributes more meaningfully to the scientific record, demonstrating a culture that prioritizes new knowledge over volume.
