📚 QS Rankings: How the 1,500+ University Search Scope Works | QS 排名体系覆盖 1,500 多所大学的检索口径
Every autumn, students and parents open the QS World University Rankings, type a university name into the search box, and read a number. That number, however, only makes sense if you understand the search scope behind it: which institutions are eligible, how many are actually ranked, what data feed the scores, and how the published list of roughly 1,500 universities relates to the tens of thousands of degree-granting institutions in the world. This article explains that scope in plain terms and shows A-Level students how to search the rankings correctly.
每年秋季，学生和家长打开 QS 世界大学排名，在搜索框里输入一所大学的名字，然后读到一个数字。但这个数字只有在理解其背后的检索口径之后才有意义：哪些院校有资格入榜、实际被排名的有多少所、分数由哪些数据支撑、以及这份约 1,500 所的榜单与全球数万所授学位院校之间是什么关系。本文用直白的语言拆解这一口径，并告诉 A-level 学生该如何正确检索排名。
1. What the QS System Actually Is | QS 排名体系究竟是什么
QS (Quacquarelli Symonds) is a UK-based higher education analytics company founded in 1990. Its flagship product, the QS World University Rankings (QS WUR), was first published in 2004 in partnership with Times Higher Education. The two organisations separated in 2009 and have published independent tables ever since. Today QS WUR sits alongside THE and the Shanghai Academic Ranking of World Universities (ARWU) as one of the three most widely cited global league tables.
QS（Quacquarelli Symonds）是一家成立于 1990 年的英国高等教育数据分析公司。其旗舰产品”QS 世界大学排名”（QS WUR）于 2004 年与《泰晤士高等教育》合作首次发布。两家机构于 2009 年分道扬镳，此后各自发布独立榜单。如今 QS WUR 与 THE、上海软科世界大学学术排名（ARWU）并列为全球被引用最广的三大排行榜。
The “1,500+” figure people quote refers specifically to the ranked list of QS WUR. The same organisation publishes many related tables: regional rankings (Asia, the Arab Region, Latin America, Emerging Europe and Central Asia), subject and faculty rankings, sustainability rankings, QS Stars, MBA and business masters rankings, and Best Student Cities. Each one has its own retrieval scope – its own eligibility rule, indicator set and cut-off. Mixing them up is the single most common error during application season.
人们口中的”1,500 多所”特指 QS WUR 的正式排名榜单。同一家机构还发布许多相关榜单：区域排名（亚洲、阿拉伯地区、拉丁美洲、新兴欧洲与中亚）、学科与学部排名、可持续发展排名、QS Stars 星级评定、MBA 与商科硕士排名，以及最佳留学城市。每一份榜单都有自己的检索口径——各自的准入规则、指标组合与截断线。把这几者混为一谈，是申请季最常见的错误。
2. Why the Ranked List Has Grown to 1,500+ | 榜单规模为何扩大到 1,500 多所
The ranked list grew edition by edition. In the early 2010s QS published roughly 700 institutions. By around 2020 the published table had reached about 1,000. From 2023 onwards the list has stood at approximately 1,500 institutions, drawn from more than 100 countries and territories, with the most recent editions reporting slightly above the 1,500 mark. Growth has come from two directions: expanding the geographic and institutional pool, and adding indicators that could be measured for more institutions.
榜单是一版一版扩大的。2010 年代初，QS 大约只发布 700 所院校；到 2020 年前后，公布数量约为 1,000 所；从 2023 年起，榜单稳定在约 1,500 所，覆盖 100 多个国家和地区，最近几版甚至略高于 1,500 所。扩容来自两个方向：一是扩大地域与院校类型的覆盖池，二是增加可以适用于更多院校的新指标。
Context matters here. Depending on how you define “university”, global counts of degree-granting higher education institutions run somewhere between 25,000 and 30,000. A ranked list of 1,500 therefore covers roughly 5-6 percent of the sector. That is not a criticism – no methodology can meaningfully compare every institution – but it does mean the table is a curated sample, not a census.
背景很关键。按”大学”定义不同，全球授学位的高等教育机构数量大约在 25,000 至 30,000 所之间。因此一份 1,500 所的榜单大约只覆盖全行业的 5%–6%。这不是批评——没有任何方法论能对每一所院校做有意义的比较——但这意味着该榜单是经过筛选的样本，而不是一次普查。
3. Eligibility: What Gets an Institution Into the Pool | 入榜资格：谁能进入候选池
QS publishes eligibility rules rather than a single test. In practice, an institution needs to satisfy several conditions before it can be ranked in the main table. The exact thresholds are reviewed each cycle, so treat the list below as the shape of the criteria rather than fixed numbers.
QS 公布的是准入规则而非单一考试。实践中，一所院校需要同时满足若干条件才可能进入主榜。具体阈值每轮都会复核，因此下面的清单是标准的”形状”，而非固定数字。
- Degree-awarding status: the institution must award degrees, normally at bachelor level or above.
授予学位的资格：院校必须授予学位，通常为学士及以上层次。 - Research output threshold: a minimum volume of indexed publications in Scopus over the assessment window.
科研产出阈值：在评估窗口期内，Scopus 索引论文数量需达到最低标准。 - Subject-level thresholds: for subject and faculty tables, separate minimums apply per discipline.
学科级阈值：学科榜与学部榜对每个学科单独设定最低标准。 - Data availability: enough verifiable data to compute the indicators without guessing.
数据可得性：有足够可核实的数据来计算指标，而不是靠推测。 - Verification: institutions are invited to confirm faculty and international staff and student numbers through QS data collection channels.
数据核验：院校会被邀请通过 QS 的数据收集渠道确认师资规模及国际师生人数。
A crucial point for students: institutions do not “apply” to be ranked in the way a company applies for certification. QS evaluates institutions using available data, then invites verification. Institutions that fail the research threshold – many specialist arts schools, conservatoires and teaching-focused colleges – simply never appear in QS WUR, however strong their teaching. They may appear instead in QS Stars, which is a ratings product, not a ranking.
对学生而言关键的一点是：院校并不像企业申请认证那样”申请入榜”。QS 依据可获得的数据进行评估，再邀请院校核验。未能达到科研阈值的院校——许多专业艺术院校、音乐学院和以教学为主的学院——无论教学质量多好，都不会出现在 QS WUR 中。它们可能出现在 QS Stars 里，而那是星级评定产品，不是排名。
4. Data Sources Behind the 1,500 Institutions | 支撑 1,500 所院校的六类数据源
The published rank is a single number, but it is assembled from several distinct data streams. Understanding where each stream comes from tells you what the rank can and cannot measure.
公布的名次只是一个数字，但它由若干条独立的数据流拼装而成。弄清每条数据流的来源，就能判断这个名次能衡量什么、不能衡量什么。
| Data stream | What it feeds | Nature of the data |
| QS Global Academic Survey | Academic Reputation | Expert opinion, large sample of academics |
| QS Employer Survey | Employer Reputation | Recruiter opinion across sectors |
| Scopus (Elsevier) | Citations per Faculty, research output screening | Bibliometric counts over a five-year window |
| Institutional submissions | Faculty Student Ratio, International Faculty and Students | Self-reported, then verified |
| Co-authorship analysis | International Research Network | Derived from publication metadata |
| Graduate outcome datasets | Employment Outcomes | Mixed institutional and third-party sources |
Two consequences follow. First, opinion surveys carry a large weight – 45 percent in the current framework combined – which is why reputation-driven institutions can outrank research-heavy ones. Second, any institution that does not submit verifiable staffing data will be scored conservatively on the ratio indicators, which can cost it hundreds of places in the long tail.
由此可得两个结论。第一，声誉调查权重很大——在当前框架中两项合计 45%——这正是声誉型院校能够排在科研密集型院校之前的原因。第二，任何未能提交可核实师资数据的院校，在比例类指标上会被保守计分，这在长尾区间可能让它损失数百个名次。
5. The Weighted Score Formula | 加权计分公式
Once every data stream has been cleaned, the overall score is a straightforward weighted sum. Each indicator is first converted to a normalised score between 0 and 100, then multiplied by its weight.
所有数据流清洗完毕后，总分就是一个直白的加权和。每项指标先被转换为 0 到 100 之间的标准化分数，再乘以对应权重。
Total Score = Σᵢ ( wᵢ × Sᵢ ) , where Σᵢ wᵢ = 1 and 0 ≤ Sᵢ ≤ 100
In words: the overall score is the sum over all nine indicators i of the weight wᵢ times the normalised indicator score Sᵢ. Because the weights sum to 1, the maximum possible overall score is 100. That is why the top of the table is compressed: the gap between rank 1 and rank 10 is tiny in score terms, even though it feels enormous in reputation terms.
用文字表述：总分等于九项指标 i 的权重 wᵢ 与标准化指标得分 Sᵢ 之积的总和。由于权重之和为 1，理论最高总分为 100。这也解释了榜首区间的”挤压效应”：第 1 名与第 10 名在分数上的差距其实很小，尽管在声誉感受上显得巨大。
A worked micro-example makes the arithmetic concrete. Suppose an institution scores 90 on Academic Reputation, 70 on Employer Reputation, 60 on Faculty Student Ratio, 80 on Citations per Faculty, 50 on International Faculty Ratio, 55 on International Students Ratio, 65 on International Research Network, 75 on Employment Outcomes and 70 on Sustainability.
一个微例可以把算术说清楚。假设某校学术声誉 90 分、雇主声誉 70 分、师生比 60 分、师均引用 80 分、国际教师比例 50 分、国际学生比例 55 分、国际研究网络 65 分、就业成果 75 分、可持续性 70 分。
0.30×90 + 0.15×70 + 0.10×60 + 0.20×80 + 0.05×50 + 0.05×55 + 0.05×65 + 0.05×75 + 0.05×70
= 27.0 + 10.5 + 6.0 + 16.0 + 2.5 + 2.75 + 3.25 + 3.75 + 3.50 = 75.25
A total of 75.25 would place such an institution comfortably inside the top few hundred in most recent editions. Notice how heavily the first two indicators drive the result: they alone contribute 37.5 of the 75.25 points.
75.25 分在最近几版中通常足以让该校稳居前几百名之内。请注意前两项指标对结果的主导作用：它们单独就贡献了 75.25 分中的 37.5 分。
6. The Nine Indicators at a Glance | 九项指标权重一览
The framework was substantially revised for the 2024 edition, when three new indicators were introduced and the weights of several existing ones were rebalanced. Comparisons across the 2023 and 2024 editions are therefore not like-for-like.
该框架在 2024 年版做了大幅修订：新增三项指标，并重新平衡了若干既有指标的权重。因此 2023 版与 2024 版之间的名次比较并非同口径对比。
| Indicator | Weight (2024 onwards) | Weight (pre-2024) |
| Academic Reputation | 30% | 40% |
| Employer Reputation | 15% | 10% |
| Faculty Student Ratio | 10% | 20% |
| Citations per Faculty | 20% | 20% |
| International Faculty Ratio | 5% | 5% |
| International Students Ratio | 5% | 5% |
| International Research Network | 5% | – |
| Employment Outcomes | 5% | – |
| Sustainability | 5% | – |
