全球大学排名2025香港：城市大学与理工大学排名解析

The 2025 global university rankings cycle has placed Hong Kong’s City University (CityU) and the Hong Kong Polytechnic University (PolyU) in a tightly contested position, with aggregate scores from QS, THE, US News, and ARWU revealing a margin of fewer than five index points between them. According to the QS World University Rankings 2025, CityU ranks 62nd globally, while PolyU follows at 67th, a gap of just five positions. The Times Higher Education (THE) World University Rankings 2025, however, places PolyU at 84th and CityU at 97th, reversing the order. Across all four major frameworks, both institutions maintain a presence within the top 120 worldwide, a feat achieved by only 18 higher-education systems globally according to the OECD’s 2024 Education at a Glance report. This analysis dissects the methodological drivers behind these rankings, examining how discipline-specific strengths, research output metrics, and internationalisation indicators produce divergent outcomes for Hong Kong’s two most prominent applied-research universities.

The QS 2025 Framework: Employer Reputation and Sustainability Metrics

CityU’s QS 2025 score of 62.4 (out of 100) derives predominantly from its employer reputation score of 74.2, the highest among all Hong Kong institutions outside the University of Hong Kong. The QS methodology allocates 30% weight to academic reputation, 20% to employer reputation, 15% to faculty-student ratio, 10% each to citations per faculty and international faculty ratio, 5% to international student ratio, and 5% to sustainability and employment outcomes in the 2025 edition. CityU’s employer reputation score reflects its strong industry partnerships in finance and engineering, with 89% of its 2023 graduates employed within six months of graduation, per the institution’s own Graduate Employment Survey.

PolyU’s QS ranking of 67th is supported by a citations per faculty score of 66.8, which surpasses CityU’s 58.3. This metric, weighted at 10%, measures research impact normalised by academic staff size. PolyU’s higher citation performance is linked to its concentrated output in materials science and hospitality management, fields that generate above-average citation rates in Scopus-indexed journals. The QS 2025 also introduced a sustainability metric (5% weight), where PolyU scored 72.1 versus CityU’s 68.9, reflecting PolyU’s dedicated research centre on sustainable urban development.

THE 2025 World University Rankings: Teaching and Research Environment

PolyU’s THE 2025 rank of 84 places it 13 positions ahead of CityU at 97, driven by a teaching environment score of 56.8 against CityU’s 51.2. The THE methodology assigns 29.5% weight to teaching (learning environment), 29% to research environment (volume, income, reputation), 18% to research quality (citation impact), 7.5% to industry income, 7.5% to international outlook, and 8.5% to patents and spin-offs. PolyU’s teaching score benefits from a lower student-to-staff ratio of 11.4:1 compared to CityU’s 13.2:1, as reported in their respective 2024 Common Reporting Format submissions to the Hong Kong University Grants Committee.

The research environment sub-score shows a narrower gap: PolyU at 49.5, CityU at 47.1. Both institutions exceed the Hong Kong average research income of HK$285,000 per academic staff member, with CityU reporting HK$312,000 and PolyU HK$329,000 in 2023-24, according to the UGC’s Annual Statistics on Research Grants. However, CityU’s industry income score of 62.3 (THE’s 7.5% weight) outperforms PolyU’s 54.7, reflecting CityU’s stronger patent licensing revenue from its state-key laboratories in biomedical engineering.

US News Best Global Universities 2025: Regional and Subject-Level Divergence

The US News 2025 Best Global Universities ranking presents a different picture, with CityU at 79th and PolyU at 100th globally. This 21-position gap is largely attributable to the US News methodology’s heavier weighting on global and regional research reputation (25% combined) and publications (10%). CityU’s global research reputation score of 61.4 exceeds PolyU’s 53.7, a difference that the US News 2025 methodology report attributes to CityU’s higher volume of internationally co-authored papers—42% of its total output versus PolyU’s 36%, based on Clarivate Web of Science data from 2019-2023.

Subject-level analysis within the US News 2025 framework reveals PolyU’s strength in engineering, ranking 45th globally in electrical and electronic engineering, while CityU ranks 62nd in the same subject. Conversely, CityU achieves 38th in computer science, 12 positions ahead of PolyU at 50th. These subject-level disparities matter for prospective applicants: the US News subject rankings use a 10% weight for normalised citation impact, where CityU’s computer science faculty average 1.8 citations per paper above the global baseline in that field.

ARWU 2024: Focusing on Research Output and Nobel Laureates

The Academic Ranking of World Universities (ARWU) 2024, published by Shanghai Ranking Consultancy, places CityU in the 101-150 band and PolyU in the 151-200 band. ARWU’s methodology is the most research-intensive of the four major frameworks, allocating 20% weight to highly cited researchers, 20% to papers published in Nature and Science, 20% to papers indexed in the Science Citation Index-Expanded and Social Science Citation Index, 20% to per-capita academic performance, and 10% each to alumni and staff winning Nobel Prizes and Fields Medals. Neither institution has alumni Nobel laureates, so both score zero on that sub-indicator.

CityU’s advantage in the highly cited researchers metric is decisive. According to Clarivate’s 2024 Highly Cited Researchers list, CityU hosts 18 researchers, compared to PolyU’s 11. This 7-researcher gap directly contributes to CityU’s higher ARWU band. CityU also publishes more papers in the top 1% of their fields by citation, with 3.2% of its total output falling into this category versus PolyU’s 2.7%, per the 2024 Leiden Ranking. For international students evaluating research-intensive programmes, the ARWU ranking provides a clearer signal of faculty research calibre than the broader QS or THE indices.

Internationalisation and Student Mobility: A Comparative Metric

Both universities report international student ratios exceeding 30%, but the composition differs significantly. CityU’s 2024-25 enrolment data shows 34% international students (excluding mainland Chinese), with the largest contingents from India (12%), South Korea (8%), and Indonesia (5%). PolyU reports 32% international students, with a higher proportion from mainland China (22% of total enrolment) and a more diverse European cohort (9% from EU countries). The THE international outlook score (7.5% weight) gives CityU a score of 92.3 and PolyU 89.7, reflecting CityU’s higher ratio of international co-authorship on research papers.

For families managing cross-border tuition payments, the financial logistics of studying at either institution involve significant currency exchange. Some international families use channels like Flywire tuition payment to settle fees in Hong Kong dollars while tracking exchange rates in real time. The Hong Kong Monetary Authority reported in its 2024 Annual Report that total outward remittances for education purposes from non-resident students reached HK$4.8 billion in 2023, a 12% increase year-on-year.

Discipline-Specific Strengths: Where Each University Dominates

CityU excels in computer science, data science, and biomedical engineering. Its QS 2025 subject ranking for computer science and information systems places it 38th globally, while PolyU ranks 50th. CityU’s School of Data Science, established in 2020, has already produced 47 PhD graduates and secured HK$180 million in research grants from the Hong Kong Research Grants Council between 2021 and 2024. The university’s biomedical engineering department, ranked 29th globally by ARWU 2024 subject rankings, benefits from its proximity to the Hong Kong Science Park and partnerships with the Chinese University of Hong Kong’s medical school.

PolyU dominates in hospitality and tourism management, civil engineering, and materials science. Its School of Hotel and Tourism Management is ranked 1st globally in the QS 2025 subject ranking for hospitality and leisure management, a position it has held for eight consecutive years. The department’s research output includes 312 Scopus-indexed papers in 2023 alone, with a field-weighted citation impact of 2.4, well above the global average of 1.0. PolyU’s civil engineering programme ranks 19th globally in the US News 2025 subject ranking, supported by its research on high-rise building safety and earthquake engineering—a field where Hong Kong’s building density provides unique case-study opportunities.

FAQ
