HKUST on the “Young University” List — QS Top 50 Under 50: From Topping the Chart to the Chase for NTU

Bottom line: The Hong Kong University of Science and Technology (HKUST, founded 1991) topped the QS “Top 50 Under 50” young-university ranking^※ in 2013, and was overtaken by Nanyang Technological University (NTU) in 2014. Since 2015, HKUST has never slipped from the global top two, closely shadowing NTU with a gap of less than two points. Meanwhile, on the THE “Young University Rankings” — a parallel league table — HKUST secured three consecutive wins from 2018 to 2020. Only by reading the two yardsticks together does one get the fullest picture of HKUST’s place in the global narrative of “emerging research universities.” (For the full composite ranking table, see HKUST Rankings Overview.)

# What is the QS “Young University” ranking, and how does it relate to the main QS league table?

Answer: The QS Top 50 Under 50 is not an independently scored specialist ranking. It is a derived table, filtered from the QS World University Rankings (WUR) using a single criterion: institutions must be founded within the last 50 years.

QS first published “Top 50 Under 50” in 2012^※, aiming to extract “emerging research universities” from the main table, which is dominated by centuries-old institutions. The logic was to prevent Cambridge, Oxford, and their like from “eclipsing” younger contenders — just three or four decades old — that were already reaching the global front rank. In 2015, QS expanded the coverage from the Top 50 to the Top 150 Under 50 (incorporating the Next 100 Under 50)^※, amplifying the window’s influence. Because the scores are drawn entirely from the main QS WUR, HKUST’s movement on the Top 50 Under 50 directly mirrors its performance on the global table; no “youth bonus” is applied.

The six indicators are: Academic Reputation, Employer Reputation, Faculty/Student Ratio, Citations per Faculty, International Faculty Ratio, and International Student Ratio. For a university barely thirty years old that manages to stand out on both reputation and citation metrics simultaneously, this rubric serves as a fair “stress test.”

# 2012 – the inaugural edition: HKUST starts at No. 2, with Warwick ahead

Answer: In the first edition of 2012, The Chinese University of Hong Kong (CUHK) topped the list as QS world No. 37, HKUST came second (QS world No. 40), the University of Warwick (UK) was third (QS world No. 50), and Nanyang Technological University was fourth (QS world No. 58).

The official press release for the inaugural QS Top 50 Under 50^※ shows that six of the top ten were from Asia. The region dominated the top bracket by pursuing a policy logic of “driving innovation and growth through new science-and-technology universities.” In 10th place, the University of California, Irvine represented the competitive ceiling from outside the Asia-Pacific. The snapshot reveals that Hong Kong had three institutions — CUHK (#1), HKUST (#2), and CityU (#9) — among the top ten, making it the densest cluster of “young-university” excellence globally.

# 2013: HKUST tops the list, ahead of Warwick and NTU

Answer: In the 2013 edition, HKUST rose from the previous year’s second place to first globally, displacing the University of Warwick from the top spot, with NTU coming in second^※.

This is HKUST’s historic zenith on the “young university” track: just 22 years after its founding, it claimed the global No. 1, barely a step removed from its run as Asia’s No. 1 in the QS World University Rankings (three consecutive years from 2011–2013). For a science-and-engineering institution that opened its doors only in 1991, that 2013 result was not a fluke spike but the outcome of systematic accumulation — by that point, HKUST’s international faculty ratio already exceeded 85%, and its Citations per Faculty was consistently among the world’s highest. Methodologically, HKUST’s rise proved that a young university built on research intensity can close the gap with centuries-old peers while simultaneously overtaking competitors of its own generation — all without decades of stored-up reputation.

# 2014: NTU tops the list for the first time, beginning HKUST’s chase

Answer: In 2014, Nanyang Technological University took the No. 1 spot on the QS Top 50 Under 50 for the first time, and has remained at the top ever since — by 2020, it had held the position for seven consecutive years^※. HKUST has held steady in second place.

NTU’s overtaking was not a story of HKUST slipping backward, but of NTU’s own explosive growth in research volume. From the late 2000s, the Singaporean government invested heavily in university-excellence development schemes, and NTU accelerated across the board: international collaborative papers, high-impact citations, and scores on the Academic Reputation survey all rose sharply. In the 2020 edition, NTU’s overall score was 91.8; HKUST’s was 80.6^※ — a gap of more than 11 points. That difference stemmed chiefly from NTU’s greater global prominence on the two subjective dimensions, Academic Reputation and Employer Reputation. NTU’s world ranking peaked at 11th in 2020; its exposure in the reputation survey far exceeded that of HKUST, which ranked further down the global table.

# Where does the gap between HKUST and NTU come from? The indicator comparison tells the story

Answer: Under the QS system, NTU leads on reputation and faculty-student ratio, while HKUST sometimes overtakes on research impact (Citations per Faculty) and internationalisation indicators.

Based on a head-to-head comparison of the two institutions’ 2019 performance published by TopUniversities^※:

This comparison reveals a structural fact: NTU wins on reputation and scale; HKUST holds its own on research quality-efficiency (density of highly-cited outputs) and depth of internationalisation. On Citations per Faculty — the purest measure of research-output quality — HKUST’s 2019 global rank of 39th was well ahead of NTU’s 87th. This indicates that HKUST’s unit efficiency of research output is higher; it is not losing on pure strength. That explains why the score gap between the two has long remained within single digits, and why HKUST has never dropped out of the top two of the QS Top 50 Under 50.

# Since 2015: HKUST a steady global No. 2, the gap shrinks to under two points

Answer: From 2015 to the present, HKUST has never fallen out of the top two of the QS Top 50 Under 50^※. In the 2024 edition, the score gap between HKUST and NTU narrowed to less than two points.

Below is a selection of verifiable year-by-year rankings:

Note: Year-by-year data for 2014–2018 is limited by archive availability. What is verifiable is that NTU has held the top spot continuously — NTU’s own press release confirms 2019 as the sixth consecutive year^※ and 2020 as the seventh^※ — while textual sources explicitly state that HKUST “has never dropped out of the top two since 2015.”

---

# Why has the gap narrowed in recent years? What has HKUST got right?

Answer: In recent years, HKUST has continued to lead on Citations per Faculty, achieved a higher proportion of international co-authored papers, and steadily raised its Academic Reputation survey score — driving forward on all three fronts simultaneously to close the gap with NTU.

According to 2024 data^※, HKUST’s Academic Reputation score reached 98.3 out of 100; Employer Reputation scored 94.6; international faculty proportion exceeded 85%; and the international co-authorship rate hit 58%, higher than NTU’s 47%. On citation growth, HKUST’s total citation count grew by 26% between 2019 and 2023, reflecting a sustained strategy of accelerating research output. HKUST’s overall QS world ranking — which had dropped in a one-off adjustment to 60th in the 2024 edition due to a methodology change — rebounded rapidly: to 47th in 2025^※, 44th in 2026^※, and 33rd in 2027^※. This sustained climb up the composite world table will directly feed into the young-university sub-ranking score, significantly raising the probability that HKUST could catch up to NTU in the coming years.

# The other yardstick: in the THE “Young University Rankings,” HKUST won three in a row

Answer: Beyond QS, Times Higher Education (THE) also publishes a “young university” ranking for institutions aged under 50. On this yardstick, HKUST is not the perennial runner-up: it was world No. 1 for three consecutive years — 2018, 2019, and 2020^※. After that, it slipped to second in 2023 and third in 2024; the ranking was discontinued after the 2024 edition.

The THE Young University Rankings were first released in 2012, and the early years were dominated by the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland. As of the 2017 edition, EPFL had been world No. 1 for three editions in a row^※; that year HKUST was ranked second (up one place from the previous edition), while City University of Hong Kong jumped 13 places to seventh — its first entry into the global top ten. Nanyang Technological University was third. That edition also left a statistical footnote: half of the top ten were from Asia, the strongest Asian showing since the ranking began.

In 2018, the landscape was redrawn. HKUST reached No. 1 in the THE Young University Rankings for the first time, then held the position in 2019 and 2020 — a three-peat^※.This stands in stark contrast to its position on the QS equivalent, where HKUST has long played second fiddle to NTU. Same university, same “young university” track — but measured by QS it is the eternal No. 2, while measured by THE it is a three-time champion. The root of the divergence lies in the differing indicator mixes of the two methodologies (THE weights teaching environment, research output, and bibliometric citation analysis more heavily; QS assigns nearly half its weighting to reputation surveys). This suggests that HKUST’s comparative advantage is concentrated at the “output end” rather than the “reputation end.”

As the 2020s began, NTU also started to overtake HKUST on the THE version.^※ HKUST slipped to second in 2023, and in 2024 was pushed to third by French institutions such as Université PSL and by NTU, which by then had been THE young-university No. 1 for two consecutive years. In other words, during 2023–2024, NTU topped both the QS and THE young-university rankings simultaneously for the first time, while HKUST dropped to second or third on both systems — the first time since 2012 that the gap between the two has narrowed in synchrony on both tables, marking an overall lead for NTU.

It is worth noting that THE decided to discontinue the Young University Rankings after the 2024 edition, and is instead reviewing the broader presentation of its rankings portfolio; hence there is no 2025 edition^※. This means that directly comparable data on the “young university” race will henceforth depend primarily on the QS table alone — cementing HKUST’s 2013 QS top spot and its 2018–2020 THE three-peat as two sealed historical peaks within this “dual-table verification” narrative.

# PolyU and CityU in the same race: Hong Kong’s “phalanx” on the QS Young University list

Answer: Hong Kong has never been a solo act on the QS Top 50 Under 50. In the 2024 edition, The Hong Kong Polytechnic University (PolyU) ranked 6th globally, and City University of Hong Kong (CityU) ranked 8th^※ — three Hong Kong institutions in the global top eight, the densest collective appearance to date on this track.

This collective result also shows that HKUST’s “perennial No. 2” status is not an isolated duel with NTU. It sits alongside two homegrown peers of a similar age, together forming a “Hong Kong young-university phalanx”: over the past five years, PolyU has climbed from 10th to 6th, and CityU from 9th to 8th^※ — both rising significantly faster than HKUST, whose steady hold on second place leaves limited room for upward movement (the only progress available is narrowing the score gap). On specific indicators, PolyU and CityU are particularly strong on internationalisation — both surpassed a score of 95 out of 100 on International Faculty and International Students, with CityU’s International Students score reaching 99.7^※ — while HKUST led the three on Employer Reputation with 94.6.

This configuration does not perfectly mirror the Hong Kong hierarchy on the composite rankings (see HKUST Composite Ranking Table^※). PolyU and CityU trail HKUST on the overall world table, but because their institutional ages are similarly young — PolyU traces roots to 1937 but only gained full university status from its predecessor polytechnic in 1994; CityU gained university status in 1994 — all three fall within the “under 50” window. On this age-filtered sub-ranking, the three form a tighter contest than their overall world ranks would suggest. For readers following the “emerging research university” track, this means HKUST, while chasing NTU for the global top spot on the QS young-university list, must also keep an eye on the closing speed of the two cross-town rivals behind it.

# What narrative value does the “young university” label hold for HKUST?

Answer: Within HKUST’s full ranking story, the label of “young university No. 1 / No. 2” carries a distinctive argument from legitimacy: it directly answers the sceptical question of how a university barely three decades old can compete with centuries-old institutions.

Founded in 1991, HKUST has with little more than thirty years of history broken into the QS world top thirty, competing alongside Imperial College London, ETH Zurich, and the University of Chicago. This achievement demands an explanation. The “young university global No. 1 / No. 2” narrative supplies the most concise and powerful answer. The idea that “new science-and-technology universities achieve leapfrog rise through research intensity”^※ is the very Zeitgeist QS explicitly assigned to this ranking at its 2012 launch. Whether for student recruitment, international partnership negotiations, or government funding submissions, the fact “33 years old, second in the world” carries more piercing force than abstract subject-level rankings.

In terms of competitive landscape, the only institution capable of truly rivalling HKUST on this table is NTU. KAIST and CityU hold steady at third and fifth, but with a substantial score gap behind the top two. This means the question of whether HKUST can retake the global No. 1 spot has become a precise algorithmic race — a contest of research-intensity growth rates and subject-reputation velocity — rather than a vague jostle of brand perception.

# Can HKUST retake the global top spot?

Answer: With a gap of less than two points in 2024 and the rapid rebound in its overall QS ranking, the contest between HKUST and NTU on the QS Top 50 Under 50 will enter its most suspenseful window within the next two to three years.

NTU, like HKUST, was founded in 1991; the two are exact institutional coevals and will hit the “50-year eligibility ceiling” in lockstep. The QS Top 50 Under 50 uses 50 years since founding as the exit threshold; by the founding dates of both institutions, 2041 stands as the theoretical final edition. Until then, both will continue to apply pressure to the global university landscape as young institutions. For HKUST, the reputation boost delivered by its QS WUR 2027 rise to 33rd globally (a jump of 11 places from the previous edition)^※ will be cashed out when the next edition of the young-university ranking is released. Whether that scoring can close — or overtake — the gap with NTU will be the next important footnote in HKUST’s “young university” story.
