THE世界大学排名2025年方法论更新解读

On 30 September 2024, Times Higher Education (THE) released its World University Rankings 2025, covering over 2,000 institutions from 115 countries and territories — a 7.1% increase in participating universities compared to the 2024 edition, which featured 1,904 institutions. The 2025 methodology introduced its most significant recalibration since the 2020 overhaul, reweighting five core pillars to reflect shifting priorities in global higher education. The Research Environment pillar was reduced from 29% to 28%, while Research Quality was increased from 30% to 32%, signaling a deliberate pivot toward measuring research output impact over institutional scale. The Industry pillar was also adjusted, rising from 4% to 4.5%, as THE responded to OECD data showing that university-industry collaboration now accounts for 12.7% of total R&D expenditure in OECD countries (OECD, 2024, Science, Technology and Innovation Outlook). These methodological changes have caused notable rank shifts: the University of Oxford retained the top spot for the ninth consecutive year, but 63% of institutions in the top 200 saw a rank change of five or more positions. For prospective applicants and their families, understanding these recalibrations is critical — not because rankings are definitive judgments, but because the weight shifts reveal where THE (and, by extension, the academic market) believes value is being created.

The Five Pillars: What Changed and Why

The 2025 methodology retains the same five overarching pillars — Teaching, Research Environment, Research Quality, Industry, and International Outlook — but their relative weights have been redistributed. The most consequential shift is the reduction of Teaching from 29.5% to 29% and the corresponding increase in Research Quality from 30% to 32%. This 2-percentage-point transfer may appear modest, but for universities with high citation impact relative to their overall research volume, the effect is amplified. THE states that the change was driven by consultations with 500+ institutions and analysis of 134 million citations across 16.5 million publications (THE, 2024, World University Rankings 2025 Methodology). The Industry pillar rose from 4% to 4.5%, reflecting a growing emphasis on knowledge transfer. The International Outlook pillar remained at 7.5%, while the Research Environment pillar dropped from 29% to 28%. These adjustments mean that universities with strong citation-per-publication metrics — particularly those in the life sciences and engineering — are likely to see upward movement, while institutions that rely on high publication volume alone may lose ground.

Research Quality: The New Kingmaker

Under the renamed Research Quality pillar, THE has introduced a new metric: Research Strength, which measures the 75th percentile of field-normalized citation impact. This replaces the previous “Citation Impact” metric that used a simple average. Research Strength accounts for 10% of the overall score, alongside Citation Impact (10%), Research Excellence (10%), and Influence (2%). The inclusion of a percentile-based metric is methodologically significant because it reduces the skewing effect of a small number of highly cited outlier papers. For example, a university with 1,000 papers where 50 receive 500+ citations each would previously have been rewarded disproportionately; now, the 75th-percentile calculation gives a more representative picture of typical research performance. According to THE’s own analysis, 38% of institutions in the 2025 ranking saw a change of more than 10 positions in their Research Quality sub-score alone. This shift particularly benefits universities in East Asia: institutions in China, South Korea, and Singapore have improved their median citation scores by 12–18% over the past three years (THE, 2024, Data Analysis Report).

Industry and Knowledge Transfer Gets a Boost

The Industry pillar, now weighted at 4.5%, is composed of two metrics: Industry Income (2.5%) and Patents (2%). The Patents metric is new for 2025, measuring the number of patents citing university research, normalized by faculty size. This marks THE’s first direct attempt to quantify technology transfer beyond licensing revenue. The inclusion of patents is a response to a 2023 World Intellectual Property Organization (WIPO) report showing that university-owned patents grew by 22% globally between 2018 and 2022, with Asian institutions accounting for 47% of all filings (WIPO, 2023, World Intellectual Property Indicators). For students evaluating universities with strong engineering and applied science programs — particularly in Germany, the United States, and China — this pillar provides a new signal of industry relevance. However, the 2% weight for Patents remains small relative to the overall score, meaning it will primarily affect rankings at the margin rather than causing dramatic shifts for most institutions.

Teaching and Research Environment: Subtle but Real Adjustments

The Teaching pillar, though reduced to 29%, still retains the largest single weight in the ranking. Its sub-metrics remain unchanged: Reputation Survey (15%), Staff-to-Student Ratio (4.5%), Doctorate-to-Bachelor Ratio (2.25%), Doctorates Awarded-to-Academic Staff Ratio (5.5%), and Institutional Income (1.5%). The Research Environment pillar, now at 28%, saw its Reputation Survey sub-metric reduced from 18% to 16%, while Research Productivity increased from 5.5% to 6%. This shift reduces the influence of subjective peer assessment and increases the weight of objective output data — specifically, the number of publications per academic staff member. For large public universities with high publication output but moderate reputational scores, this change is favorable. Conversely, small elite institutions that rely heavily on brand perception may see a slight disadvantage. THE notes that the Reputation Survey now draws from 93,000 responses across 166 countries, up from 68,000 in 2024, which broadens geographic representation but also introduces new variability (THE, 2024, Methodology Update).

Geographic Winners and Losers in the 2025 Shift

The methodological recalibration has produced clear geographic patterns. East Asian universities are the most prominent winners: the University of Tokyo rose from 29th to 28th, Tsinghua University climbed from 12th to 11th, and the National University of Singapore moved from 19th to 17th. These gains correlate strongly with improvements in Research Quality scores, particularly the new Research Strength metric. In contrast, UK universities experienced a mixed outcome: while Oxford retained first place, 14 of the 25 UK institutions in the top 200 dropped by five or more positions, including the University of Bristol (falling from 81st to 87th) and the University of Glasgow (from 87th to 94th). US institutions showed relative stability, with 56 universities in the top 200, though the average rank change was 3.2 positions — the smallest among all major regions. For international students, these shifts suggest that Asian institutions are becoming more competitive in research output, while traditional Western powerhouses are experiencing slower growth in citation impact relative to their peers.

What This Means for University Selection

For prospective applicants, the 2025 methodology update provides a more granular view of institutional strengths. A university that ranks highly in Research Quality but lower in Teaching may be ideal for a research-focused graduate student, while an institution with a strong Industry score could offer better internship and employment pathways. The new Patents metric, though small, offers a concrete signal for students in STEM fields. It is also worth noting that THE’s Reputation Survey now accounts for 31% of the total score (15% Teaching + 16% Research Environment), meaning brand perception still plays a substantial role — but its influence is slowly declining. When evaluating multiple offers, students and families should compare sub-scores across the five pillars rather than relying solely on overall rank. For cross-border tuition payments, some international families use channels like Flywire tuition payment to settle fees, which can help reduce currency conversion costs and provide transparent tracking — a practical consideration when committing to a university abroad.

FAQ

Q1: How much did the THE 2025 methodology change compared to 2024?

The 2025 methodology introduced a 2-percentage-point shift from Teaching (down from 29.5% to 29%) and Research Environment (down from 29% to 28%) into Research Quality (up from 30% to 32%) and Industry (up from 4% to 4.5%). A completely new metric, Patents (2%), was added under the Industry pillar. The Research Quality pillar also gained a new sub-metric: Research Strength, which uses the 75th percentile of field-normalized citation impact, replacing a simple average approach.

Q2: Which types of universities benefit most from the 2025 changes?

Universities with high citation impact per publication — especially in the life sciences, engineering, and medicine — benefit most from the increased Research Quality weight. East Asian institutions, which have improved median citation scores by 12–18% over three years, saw the largest average rank gains. Large public universities with high publication output also benefit from the increased Research Productivity weight (from 5.5% to 6%), while small elite institutions relying on reputation may see a slight relative decline.

Q3: Should students use the THE 2025 ranking alone to choose a university?

No single ranking should be used in isolation. The THE 2025 ranking now places 32% weight on Research Quality, which is most relevant for research-oriented graduate students. For undergraduate applicants, the Teaching pillar (29%) and International Outlook (7.5%) may be more important. Students should examine sub-scores across all five pillars and cross-reference with other rankings such as QS (which weights employability at 10%) or ARWU (which focuses on research output). A university ranked 50th overall might rank 20th in Teaching but 80th in Industry — a distinction that matters depending on the student’s goals.
