Chang'an University

EXECUTIVE SUMMARY AND STRATEGIC VISION

Chang'an University presents a robust scientific integrity profile, with an overall risk score of -0.111 that indicates a performance well-aligned with national and international standards. The institution demonstrates exceptional strengths in areas critical to research sustainability and transparency, particularly its very low rates of hyper-authored output, redundant publications, and a minimal gap between its overall impact and the impact of its internally-led research. These results signal a strong foundation of internal capacity and a culture that prioritizes meaningful contributions over inflated metrics. This operational excellence is reflected in its strong global positioning in key thematic areas, with SCImago Institutions Rankings placing it in the global Top 100 for Earth and Planetary Sciences and in the Top 200 for Environmental Science, Engineering, and Mathematics. However, the analysis also identifies two areas requiring strategic attention: a medium-risk level in Institutional Self-Citation and Output in Institutional Journals, both of which are notably higher than the national average. These signals of potential academic endogamy could, if unaddressed, challenge the institution's pursuit of global excellence by creating a perception of insularity. To fully leverage its demonstrated strengths and solidify its international reputation, it is recommended that the university review its internal publication and citation policies to ensure they encourage broad external validation and global engagement, thereby reinforcing its commitment to universally recognized standards of scientific excellence.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution exhibits a Z-score of -0.281, which is lower than the national average of -0.062. This prudent profile suggests that the university manages its collaborative frameworks with more rigor than the national standard. While multiple affiliations are a common feature of modern research, the institution's controlled rate indicates clear and transparent policies regarding researcher appointments and partnerships. This helps prevent strategic "affiliation shopping" and ensures that institutional credit is claimed legitimately, reflecting a well-governed and organized approach to academic collaboration.

Rate of Retracted Output

With a Z-score of -0.137, below the national average of -0.050, the institution demonstrates a prudent and effective approach to quality control. This lower-than-average rate of retractions is a positive signal, suggesting that the university's pre-publication review mechanisms and supervisory processes are robust. Rather than indicating systemic failures, this controlled level points to a healthy integrity culture where potential errors are likely identified and corrected before they can escalate, safeguarding the quality and reliability of its scientific record.

Rate of Institutional Self-Citation

The university's Z-score for this indicator is 1.153, a figure that shows high exposure to risk when compared to the national average of 0.045. This value suggests that the institution is more prone than its national peers to practices that could lead to scientific isolation. A certain level of self-citation is natural, but this disproportionately high rate warns of a potential 'echo chamber' where the institution's work may be validated internally without sufficient external scrutiny. This dynamic risks creating an endogamous impact that is oversized by internal citation patterns rather than by genuine recognition from the global scientific community, a trend that warrants strategic review.

Rate of Output in Discontinued Journals

The institution's Z-score of -0.153 is notably lower than the national average of -0.024, indicating a prudent profile in its selection of publication venues. This demonstrates a commendable level of due diligence, as the university effectively avoids channeling its research into journals that fail to meet international ethical or quality standards. By maintaining a low rate of publication in such outlets, the institution protects its resources and reputation from the risks associated with predatory or low-quality publishing practices.

Rate of Hyper-Authored Output

With a Z-score of -1.255, the institution shows a very low incidence of hyper-authorship, a figure that is well below the already low-risk national average of -0.721. This low-profile consistency demonstrates an exemplary approach to authorship. The near-total absence of this risk signal aligns with the best national standards and suggests that the university's research culture values transparency and clear individual accountability, successfully distinguishing between necessary large-scale collaboration and potentially problematic practices like honorary authorship.

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

The institution registers a Z-score of -0.955, reflecting an almost complete absence of risk and outperforming the national average of -0.809. This state of total operational silence is a significant strength, indicating that the university's scientific prestige is built upon its own structural capacity and intellectual leadership. The minimal gap suggests that its high-impact research is not dependent on external partners but is driven by internal talent. This demonstrates a sustainable and autonomous model of excellence, where institutional impact is a direct result of its own core research capabilities.

Rate of Hyperprolific Authors

The university's Z-score of -0.382 contrasts sharply with the national average of 0.425, showcasing strong institutional resilience. While the national system shows a medium-level vulnerability to hyperprolificacy, the institution's control mechanisms appear to effectively mitigate this systemic risk. This low score suggests that the university fosters a healthy balance between productivity and quality, discouraging practices such as coercive authorship or the prioritization of quantity over meaningful intellectual contribution, thereby protecting the integrity of its academic record.

Rate of Output in Institutional Journals

The institution's Z-score of 1.110 marks a moderate deviation from the national average of -0.010, indicating a greater sensitivity to this risk factor than its peers. This reliance on in-house journals raises potential conflicts of interest, as the institution acts as both judge and party in the publication process. This high rate warns of a risk of academic endogamy, where research might bypass rigorous independent peer review. Such a practice could limit the global visibility and competitive validation of its scientific output, potentially creating 'fast tracks' for publication that do not align with international standards.

Rate of Redundant Output

With a Z-score of -0.632, which is even lower than the national average of -0.515, the institution demonstrates total operational silence regarding this risk. This exceptionally low rate of bibliographic overlap between publications is a strong indicator of a research culture that values substance over volume. It suggests that the university's authors are committed to publishing complete and significant studies rather than engaging in 'salami slicing' to artificially inflate their productivity, thereby contributing robust and meaningful knowledge to the scientific community.
