Ocean University of China

EXECUTIVE SUMMARY AND STRATEGIC VISION

Ocean University of China demonstrates a robust scientific integrity profile, reflected in an overall risk score of -0.186. This indicates a performance that is not only solid but also superior to many of its national peers. The institution's primary strengths lie in its exceptional scientific leadership, with internally-led research showing significantly higher impact than its collaborative output, and a commendable commitment to publishing in externally validated, high-quality journals. These practices are complemented by very low rates of redundant publications. However, areas requiring strategic attention include a tendency towards high institutional self-citation and a notable concentration of hyperprolific authors, both of which exceed national averages. The university's outstanding global reputation, particularly in key thematic areas such as Agricultural and Biological Sciences, Earth and Planetary Sciences, and Environmental Science, as evidenced by SCImago Institutions Rankings data, aligns with its mission to become a high-level university with international visibility. To fully realize this vision, it is crucial to address the identified risks, as practices suggesting insularity or a focus on quantity over quality could undermine the perception of excellence and global engagement that the institution rightfully seeks. By proactively managing these vulnerabilities, Ocean University of China can further solidify its position as a world-class, research-oriented institution approaching its centenary.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution presents a Z-score of -0.299, a value indicating a more controlled approach compared to the national average of -0.062. This prudent profile suggests that the university's processes for managing affiliations are more rigorous than the national standard. While multiple affiliations are often a legitimate result of researcher mobility or partnerships, this lower-than-average rate indicates that the institution is effectively mitigating the risk of strategic attempts to inflate institutional credit or engage in “affiliation shopping,” thereby ensuring that its collaborative footprint is transparent and accurately reflects genuine scientific partnerships.

Rate of Retracted Output

With a Z-score of -0.080, the institution's rate of retracted publications is in close alignment with the national average of -0.050. This reflects a state of statistical normality, where the level of risk is as expected for its context and size. Retractions are complex events, and this score does not suggest a systemic failure in quality control. Instead, it is indicative of a responsible supervisory environment where unintentional errors are corrected as part of the scientific process, a practice consistent with the integrity standards observed across the country.

Rate of Institutional Self-Citation

The institution's Z-score for self-citation is 0.823, a figure that indicates high exposure to this risk and is significantly more pronounced than the national average of 0.045. This suggests the center is more prone to showing alert signals than its environment. While a certain level of self-citation is natural, this disproportionately high rate signals a potential for concerning scientific isolation or 'echo chambers' where work is validated internally without sufficient external scrutiny. This value warns of the risk of endogamous impact inflation, suggesting that the institution's academic influence may be oversized by internal dynamics rather than broad recognition from the global community, a trend that requires careful review.

Rate of Output in Discontinued Journals

The university demonstrates a prudent profile with a Z-score of -0.323, which is substantially lower than the national average of -0.024. This indicates that the institution manages its publication processes with more rigor than the national standard. A high proportion of output in discontinued journals can be a critical alert regarding due diligence, but this low score shows the university is effectively avoiding channels that fail to meet international ethical or quality standards. This proactive selection protects the institution from severe reputational risks and demonstrates a strong commitment to information literacy, preventing the waste of resources on 'predatory' or low-quality practices.

Rate of Hyper-Authored Output

With a Z-score of -1.062, the institution shows a significantly lower incidence of hyper-authored publications compared to the national average of -0.721. This prudent profile suggests that the university's authorship practices are managed with more rigor than the national standard. Outside of 'Big Science' contexts where extensive author lists are normal, a high rate can indicate author list inflation. The university's low score, however, points to a healthy culture of authorship that values individual accountability and transparency, successfully distinguishing between necessary massive collaboration and potentially problematic 'honorary' authorship practices.

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

The institution exhibits a Z-score of -1.441, a figure that signals total operational silence on this risk indicator and is even stronger than the national average of -0.809. A wide positive gap can suggest that an institution's prestige is dependent on external partners rather than its own capacity. However, this exceptionally low score indicates the opposite: the impact of research led by the institution is significantly higher than its overall average. This is a powerful sign of structural scientific strength and sustainability, demonstrating that excellence metrics result from real internal capacity and intellectual leadership, not just strategic positioning in collaborations.

Rate of Hyperprolific Authors

The institution's Z-score of 0.702 in this category is notably higher than the national average of 0.425, indicating a high exposure to this risk. This suggests the center is more prone to showing alert signals related to extreme individual productivity than its environment. While high productivity can reflect leadership, extreme volumes often 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 the integrity of the scientific record and warrant a qualitative review.

Rate of Output in Institutional Journals

With a Z-score of -0.268, the institution operates at a very low risk level, which is even more conservative than the low-risk national average of -0.010. This demonstrates a low-profile consistency where the absence of risk signals aligns with, and improves upon, the national standard. Excessive dependence on in-house journals can raise conflicts of interest and limit global visibility. The university's minimal use of such channels is a strong positive signal, indicating a commitment to independent external peer review and avoiding the risk of academic endogamy, thereby ensuring its scientific production is validated through standard competitive processes.

Rate of Redundant Output

The institution's Z-score of -0.543 is almost identical to the national average of -0.515, demonstrating integrity synchrony and total alignment with an environment of maximum scientific security. A high value in this indicator would alert to 'salami slicing,' where studies are fragmented to artificially inflate productivity. The university's very low score, in line with the national trend, confirms a focus on producing coherent, significant studies over prioritizing volume. This practice upholds the integrity of the scientific evidence base and avoids overburdening the peer-review system.
