One-line positioning: Among research postgraduates at The Chinese University of Hong Kong (Shatin campus), non-local students account for roughly six in ten (2021/22 academic year), with mainland China as the core source; across Hong Kong's eight UGC-funded universities, international students made up 87%^※ of research postgraduates in 2024/25, of whom as many as 92%^※ came from mainland China; mainland doctoral students generally follow a path of "returning north" to employment in mainland academia after earning their credentials, and the two-way movement of talent is becoming increasingly institutionalised within the Greater Bay Area policy framework.

# How many mainland students are there among CUHK postgraduates?

The postgraduate population at The Chinese University of Hong Kong (Shatin campus) has expanded steadily in recent years. According to the CUHK Graduate School's website^※, in the 2025/26 academic year the University enrolled more than 17,900 postgraduate students across over 230 programmes spanning eight Faculties. Across the postgraduate body as a whole, the share of non-local students is markedly higher than at undergraduate level.

According to a Times Higher Education report^※, in the 2021/22 academic year non-local students already made up 60% of all CUHK postgraduates (definition: all postgraduates, both taught and research, hereafter the same). By contrast, non-local students accounted for only about 13% at undergraduate level. The gap reflects two institutional differences. First, the government caps the number of non-local students in UGC-funded undergraduate places (now raised from 20% to 40%), while taught postgraduates are not subject to any quota. Second, research postgraduate (MPhil/PhD) places enjoy greater flexibility at the institutional level and are recruited globally.

At the territory-wide level, international students accounted for roughly 80% of research postgraduates (i.e. MPhil/PhD) at the eight funded universities, rising to 87%^※ by 2024/25 (definition: all eight UGC-funded universities; data year: 2024/25). This share has climbed about seven percentage points over the past decade. At CUHK's main campus, the proportion of non-local students (including both mainland and international) among students in UGC-funded programmes has loosened in step with the territory-wide quota policy; for the neutral data skeleton, see 00-overview/key-numbers-dashboard.md.

One easily confused definition needs clearing up first: "mainland students" at undergraduate level are admitted mainly through the mainland gaokao unified recruitment or through the University's own independent admissions (see also 02-admissions/mainland-gaokao-admission-track.md), whereas research postgraduates follow a different logic — they are recruited directly by departments and supervisors according to research needs, with places and funding tightly bound together, and are barely constrained by the undergraduate non-local quota line. This is the institutional root of why the mainland share runs so much higher at postgraduate than undergraduate level.

# How dominant is the mainland source among doctoral students?

Within the international-student body at research postgraduate (PhD/MPhil) level, the concentration of mainland origins is particularly striking. According to Times Higher Education^※, among international research postgraduates at Hong Kong's funded universities, those from mainland China accounted for 92% in 2024/25 (definition: mainland share among international research postgraduates, 2024/25), up from 86% a decade earlier. In other words, at PhD/MPhil level the picture has become close to a "single-source mainland" pattern.

At CUHK's main campus, the University does not publish admission breakdowns by source region, but its 2019 data (source: CUHK Strategic Plan 2021–2025^※) show that, of 13,183 postgraduates in total, 6,065 (46%) were non-local and "mostly from mainland China", consistent with the territory-wide trend. Combining these figures with the rise to 60% non-local in 2021/22, one can infer that both the absolute number and the share of mainland-origin students have increased since 2019 (definition: including taught and research postgraduates; not figures independently published by CUHK).

This pattern is not unique to CUHK; it is the shared baseline of all eight funded universities. "Nine in ten international research postgraduates come from mainland China" is a territory-wide weighted average; the universities differ only in degree of concentration, not in kind. If the definition is widened to include all Chinese students enrolled in Hong Kong (undergraduate, taught and research programmes alike), according to a compilation of UGC data^※ CUHK enrolled roughly 3,872 mainland Chinese students in 2024/25, ranking third among the eight universities, behind only HKU and PolyU. In short, whether measured by postgraduate share or by absolute numbers, mainland sources carry weight at the front of CUHK's research enterprise; the associated admission volume, hostel and tuition definitions are covered separately in 〈内地生宿舍与就业去向考〉 and 02-admissions/tuition-and-scholarships.md.

# What chiefly draws mainland doctoral students here?

Understanding why mainland postgraduates choose CUHK (and other Hong Kong institutions) requires separating two levels: "institutional pull" and "individual strategic calculation".

Institutional pull. Hong Kong's academic environment offers resources that the mainland university system does not: a tradition of academic freedom under the common law, direct access to international peer-review networks, an English-dominant publication and exchange culture, and an information environment unconstrained by mainland internet restrictions. A more immediate inducement comes from the scholarship system: the Hong Kong PhD Fellowship Scheme (HKPFS)^※, established by the Research Grants Council (RGC) in 2009, provides each awardee an annual living allowance of HK$344,400 plus a conference and research travel allowance of HK$14,400, for a period of three years. The scheme is open globally — applications are welcome "regardless of nationality, work experience and ethnic background" — and in practice attracts a large pool of applicants from mainland China's 985/211 universities each year (China's elite-university funding schemes). CUHK's own complementary awards and fee definitions are set out in 02-admissions/tuition-and-scholarships.md.

Worth noting is that the quota itself is expanding: HKPFS awards grew from 350^※ in 2024/25 to 400 in 2026/27, in step with the territory-wide expansion of research postgraduate places. The application route is also demanding — applicants must first secure nomination from their intended department before undergoing cross-institutional review by the RGC; the application window for the 2026/27 round runs from 1 September to 1 December 2025^※. Unofficial compilations of past winners' backgrounds consistently note that applicants with existing publications succeed at markedly higher rates than those without, which echoes the finding of the qualitative study cited below that "research conditions and the publication environment are the foremost motive": the HKPFS is both a pull and, at the source, a filter that has already selected for mainland applicants with a research track record.

Individual strategic calculation. A qualitative study of 37 mainland students pursuing doctorates at Hong Kong's publicly funded universities (published 2023; sample spanning multiple universities, in both STEM and humanities) found that the publication environment, supervisor resources and research conditions were the three leading motives; moreover, over six in ten respondents were aged 23–27, at the early stage of planning an academic career, viewing Hong Kong as a transitional academic platform between the "international" and the "mainland".

# What is it actually like to do a PhD in Hong Kong?

The scholarship and the international platform are the ledger side of the "pull". The other side is the pressure mainland doctoral students actually bear once they enter Hong Kong's academic system. In the qualitative study^※ mentioned above, about 49% of the 37 respondents were women, over 70% were aged 23–27, the disciplinary spread was dominated by STEM (about 24%), social sciences (about 19%) and medicine (about 16%), and over 40% had already been studying in Hong Kong for more than three years — a young cohort in the early career stage, predominantly in science and engineering.

The academic pressures the study identified are quite specific. First, high supervisor expectations, especially in STEM, where the quantity and quality of publications are the explicit yardstick; respondents commonly mentioned an adjustment period at the outset in which the "research topic was too hard". Second, self-discipline: doctoral training emphasises independence and time management, and one respondent admitted it was hard to judge "how long a task would take", leaving the pace entirely to oneself. Third, peer comparison: in the expectation of a competitive academic job market, comparing publication records with lab-mates and cohort-mates creates sustained psychological pressure. Fourth, those who switched research fields carried the extra burden of "learning everything from scratch". The closer graduation, the more acute the anxiety over competition for academic posts — which directly foreshadows the "most plan to return north" pattern of destinations discussed below.

On the adaptation front, the most common friction is Cantonese. The study notes that Cantonese proficiency varies by home region: students from Guangdong cope relatively easily, while those from northern and western provinces struggle more; mainland doctoral students serving as teaching assistants feel the communication gap most keenly when undergraduates "just speak Cantonese". This language barrier is not merely an inconvenience of daily life; it also affects teaching participation, local social life and the feasibility of later staying on in Hong Kong for work (the Cantonese and job restrictions facing those seeking local employment are covered in 〈内地生宿舍与就业去向考〉). Expensive and cramped accommodation, and differences in food and climate, are the everyday adjustments northern students mention most often. The study also touches on differences between the two places in social and political environment; per this archive's convention we do not elaborate here, and relevant external sources are listed in 18-wilder-movements.

# Where do doctoral graduates go next — "north" or stay in Hong Kong?

According to the same qualitative study^※, most mainland doctoral respondents planned to return to mainland China for employment after graduation, citing the limited number of academic posts in Hong Kong, intense competition, and the substantial expansion in hiring at mainland universities in recent years, which offers doctoral graduates a broader job market. Some respondents also mentioned that ties of family and social networks on the mainland were an important factor in ultimately returning.

This flow pattern — mainland as the source of students and mainland as the primary employment destination — forms an "arc of movement" around research postgraduates at Hong Kong universities: mainland students travel "south" to earn an international credential, then "north" carrying academic capital back with them. The pattern aligns structurally with the positioning of "Hong Kong as a scientific research transit point".

Some doctoral graduates, however, stay on as research assistants (RAs) or postdoctoral fellows, forming a short-term residence. Certain CUHK departments also actively recruit outstanding mainland doctoral graduates as research staff, concentrated especially in STEM and the life sciences, to sustain the day-to-day operations of the University's four State Key Laboratories (see next section). The Cantonese threshold and exclusion from civil-service posts faced by those seeking local employment, and the operation of the IANG pathway, are not repeated here; see the companion piece 〈内地生宿舍与就业去向考〉.

# How do CUHK's State Key Laboratories link research talent across the two places?

The Chinese University of Hong Kong currently operates four State Key Laboratories, all approved by the Ministry of Science and Technology of the People's Republic of China:

Among these, the State Key Laboratory of Quantum Information Technologies and Materials received its plaque on 25 August 2025^※, with Professor Liu Ren-Bao as Director, focusing on quantum sensing, nanophotonics, quantum materials and quantum information theory. At the plaque-presentation ceremony, CUHK Vice-Chancellor and President Dennis Lo Yuk-ming stressed that the University was "leveraging its unique strengths to integrate into national development, functioning through cooperation and talent exchange between Hong Kong, Macau and the mainland".

Institutional as they are, these four laboratories sit simultaneously within Hong Kong's academic system and the mainland's Ministry of Science and Technology evaluation framework, forming an important institutional conduit for absorbing mainland research personnel, including postdoctoral fellows and visiting researchers. Mainland-enrolled students or mainland visiting researchers involved in laboratory projects thus constitute de facto nodes of "two-way research talent flow". The history and research directions of the four laboratories are set out in 04-research/state-key-laboratories.md.

# How does national research funding flow "south" into CUHK's laboratories?

If students are the people who move "south", funding is the other "south-bound" channel opened only in recent years — and the direction of funding flows directly determines how many doctoral students a research team can recruit and how many postdocs it can support. In the past, mainland fiscal research funds in principle did not cross the border into Hong Kong; from 2018 this pattern began to break, as the National Natural Science Foundation of China (NSFC) progressively opened its talent schemes to Hong Kong researchers.

The timeline runs roughly as follows: the Excellent Young Scientists Fund (Hong Kong and Macau) opened to the two SARs for the first time in 2019^※; the Young Scientists Fund has accepted applications from Hong Kong scholars since 2022; and in 2024, the NSFC's top-tier young-talent scheme, the National Science Fund for Distinguished Young Scholars, opened to Hong Kong and Macau researchers for the first time.

The 2024 round alone gives a sense of the scale. According to the CUHK Communications and Public Relations Office^※, 25 CUHK scholars received NSFC funding totalling over RMB 41.7 million, distributed across three tiers:

For an individual research group, these funds mean the principal investigator has more resources to create postgraduate places and pay research-assistant salaries. For a mainland doctoral student, the funding underpinning the doctoral project may well come from two sources at once — the Hong Kong RGC and the mainland NSFC. This is the budget-level shape of "two-place research": people come from the mainland, money comes from both mainland and Hong Kong, and the outputs count simultaneously under two evaluation frameworks. With funding flowing in both directions, the positioning of "Hong Kong as a scientific research transit point" has extended from the personnel level to the financial.

# For a PhD who wants to stay in Hong Kong for research, what formal pathway exists?

Finishing a doctorate does not mean an immediate "return north"; there is often a postdoctoral sojourn in between, and Hong Kong has in recent years turned that segment into an institutional channel with funding. The RGC runs a postdoctoral scheme for early-career researchers — formerly the RGC Postdoctoral Fellowship Scheme (PDFS), renamed the Junior Research Fellow Scheme (JRFS) from the 2025/26 selection cycle^※. Each round funds 60 fellows to undertake full-time postdoctoral research at UGC-funded universities, for 24 months, extendable by up to 12 months as needed; the current annual stipend is about HK$425,000 (including roughly HK$13,500 in conference travel allowance), adjusted annually by the Composite Consumer Price Index.

For mainland doctoral graduates, two features of the JRFS matter. First, it is explicitly open to "local and non-local" postdoctoral researchers, and anyone who obtained a doctorate after 1 January 2022 falls within the eligibility window; mainland newly minted PhDs in Hong Kong can therefore equally be nominated by CUHK. Second, awardees must "obtain the legal right to work and stay in Hong Kong" during the fellowship period — a clause that directly links postdoctoral funding to the right of residence, and in practice encourages a cohort of mainland researchers who have completed doctoral training in Hong Kong to remain rather than return immediately. Beyond the JRFS, further postdoctoral and research-assistant posts are hired directly by research groups using RGC or NSFC funds, with salaries and contract lengths set by project budgets and outside public selection.

This channel interlocks closely with the four State Key Laboratories in terms of manpower: the day-to-day operation of the laboratories needs a stable pipeline of postdocs and research staff, and the JRFS plus group-hired posts are precisely what turns "a brief stay in Hong Kong" from an individual choice into a funded, staged arrangement. For many mainland doctoral students, "doing two or three years of postdoctoral work in Hong Kong first, then deciding where to go" has thus become a viable third path between "staying in Hong Kong" and "returning north".

# How is CUHK-Shenzhen extending the postdoctoral pathway?

The Chinese University of Hong Kong, Shenzhen (CUHK-Shenzhen), operating independently as a mainland jointly-run university, achieved a landmark breakthrough in the postdoctoral system in recent years. In November 2023, it was approved to establish three postdoctoral research mobile stations, covering computer science and technology, materials science and engineering, and applied economics. An inauguration ceremony was held on 22 January 2024^※. This was the first time the Ministry of Human Resources and Social Security had granted eligibility for postdoctoral mobile stations to a sino-foreign jointly-run university, making CUHK-Shenzhen the first such institution approved — a significant institutional precedent.

Before this, since 2017 CUHK-Shenzhen had recruited postdoctoral researchers jointly with mainland universities such as the University of Science and Technology of China and the University of Electronic Science and Technology of China, training more than 300 postdoctoral researchers in total (as of 2023; definition: through the joint-training mechanism). The independent approval of the mobile stations marks a further clarification of CUHK-Shenzhen's standing within the mainland higher education system, and provides a firmer institutional basis for the triangular movement of talent among CUHK (Shatin), CUHK(SZ) and mainland universities.

In scale, the CUHK-Shenzhen Graduate School was established in 2015; according to the Graduate School's website^※, it currently enrols more than 4,000 postgraduate students across roughly 54 master's and doctoral programmes, of which 26 are research-oriented master's–doctoral programmes and 28 are taught master's programmes, covering data science, materials, computer science, economics and life and health. To take the School of Data Science as an example, its PhD programmes in data science and computer science recruit continuously, with doctoral tuition in 2024/25 at around RMB 115,000 per year. This postgraduate system shares some supervisors and degree frameworks with the Shatin campus, and forms the physical basis for mainland doctoral students to move between "one university, two campuses" — much joint supervision of projects, and the shuttling of samples and data, unfolds along this Shenzhen–Hong Kong axis.

The CUHK Shenzhen Research Institute (SZRI), operating since 2007 at the Virtual University Park in Shenzhen's Nanshan District, focuses mainly on technology transfer and corporate collaboration, as well as cultivating high-end professional talent locally. According to the Institute's own introduction, it is positioned as "an important base for CUHK's development in the mainland, advancing the University's innovation and entrepreneurship projects while also serving as a bridge connecting Hong Kong and Shenzhen".

# The Loop: why do Shenzhen–Hong Kong research talents converge here?

If the Shenzhen Research Institute was CUHK's earliest "crossing-the-river" outpost, the point of greater policy focus in recent years is the Hetao Shenzhen-Hong Kong Science and Technology Innovation Cooperation Zone — a strip of innovation enclave straddling the Shenzhen River, linking the parks on both the Shenzhen and Hong Kong sides into one. It matters for this article because it turns "two-way research talent flow" from paper institutionality into a physical space commutable on a daily basis.

According to an introduction by the Liaison Office of the Central People's Government in Hong Kong^※, the State Council has assigned the Hetao cooperation zone three roles: "a pioneering zone for open cooperation in Shenzhen–Hong Kong technological innovation, a pilot zone for internationally advanced rules of technological innovation, and a cluster zone for pilot-scale conversion in the Greater Bay Area". The Shenzhen-side park has already gathered R&D centres of a number of Fortune 500 companies, landing projects from several of Hong Kong's world top-100 universities, and more than 15,000 scientific and technological personnel.

CUHK maintains a presence here through the CUHK Shenzhen–Hong Kong Innovation Research Institute (Futian)^※, positioned as a research institute focused on robotics, artificial intelligence and medicine; on the CUHK-Shenzhen side sits the Shenzhen Hetao College, designated by the Ministry of Education as a national pilot zone for cultivating top-notch AI talent, built around an internationalised, interdisciplinary model of industry–university–research collaboration. For research postgraduates and postdocs, the significance of Hetao lies in unblocking cross-border funding use, sample customs clearance and personnel travel: a mainland doctoral student can run experiments in a laboratory on the Shenzhen side, report at supervisory group meetings on the Hong Kong side, and have enrolment, funding and outputs belonging to two separate systems yet closed within a single project. Hetao thus offers one of the few real-world instances where the bidirectional "south–north" flow is compressed into walking distance at both ends.

# The policy environment: tension between non-local expansion and mainland concentration

Hong Kong's 2023 Policy Address announced that the cap on non-local students in UGC-funded undergraduate places would rise from 20% to 40% (effective 2024/25). Two years later, the 2025 Policy Address^※ raised the cap further to 50% (effective 2026/27), while explicitly holding the 15,000 UGC-funded places for local students unchanged — what expands is the self-financed non-local quota, not local places. Taught postgraduates have never been bound by this cap and recruit freely.

For research postgraduates, the 2025 Policy Address loosened another, more hidden gate: the cap on over-enrolment of self-financed research postgraduate students, raised from the equivalent of 100% of funded places to 120%. This means departments may, on top of UGC-funded research places, recruit an additional two in ten self-financed research students (including doctorates). Since the overwhelming majority of these self-financed research students come from mainland China, the provision in effect reserves institutional space for a further expansion of mainland doctoral intake. Support comes on the housing side too: the Development Bureau and the Education Bureau launched the "City in the Campus" scheme in July 2025^※, encouraging the market to convert commercial buildings and hotels into student hostels; together with projects under the Student Hostel Development Fund, more than 14,300 places are expected once fully completed, directly addressing the housing pressure from the surge in non-local research postgraduates (details of the hostel guarantee for non-local students and the off-campus hostel at Tai Po are in the companion piece 〈内地生宿舍与就业去向考〉).

The expansion policy, however, has drawn mixed reactions at the institutional level. According to the THE report^※, a CUHK department head (anonymous) said plainly that the University needs "to work harder to recruit international students, particularly from the Belt and Road countries", rather than continuing to rely on the mainland source — otherwise "internationalisation" may in substance amount to little more than expansion from a single source.

That remark reflects a subtle divergence between the policy level and the institutional level: the SAR government is positioning Hong Kong as an "international education hub", yet in the actual recruitment of research postgraduates — especially doctorates — the concentration of mainland origins is already a structural reality, pointing in the same direction whether measured by admission volume, the composition of scholarship applicants, or research-project collaboration.

# "South–north": institutionalised mobility or structural dependence?

Pulling together the threads above, the flow of talent between the two places at CUHK's postgraduate level can be summarised as follows:

Within the overall Greater Bay Area strategy, this flow pattern is held up as a positive example of the "free movement of talent factors". But some scholars note that if the concentration of mainland origins keeps rising, Hong Kong universities' goal of "genuine internationalisation" in their research postgraduate body — attracting diverse sources from Asia, Africa, Latin America, Europe and North America — will face structural obstacles. The two-way flow of funding (NSFC moving south) and of people (doctoral students moving south, outputs and some talent moving north) compounds, making the pattern more institutionalised under the Greater Bay Area strategy while simultaneously deepening the structural dependence on a single source.
