QS国际教员比例 国际研究网络 各占5%含义
QS 世界大学排名 2027 版在 2026 年 6 月 18 日公布，一共 1,504 所院校入榜。翻开指标表，全球参与这一栏下面挂着四个名字，其中三个都标着 5%。国际教员比例与国际研究网络就是其中两个，很多学生以为这两个指标只是陪跑的边角料，其实 QS 官网把它们各自的算法写得很具体，读完能直接判断一所学校在国际化维度上的分量。
QS released the 2027 edition of its World University Rankings on 18 June 2026, and 1,504 institutions made the cut. Two of the names under the Global Engagement lens carry exactly the same weight, International Faculty Ratio and International Research Network at five per cent each; the detail in the official documentation is enough to judge where a university really stands.
全球参与 15% 与三个 5% 的构成
权重表把全球参与这一整个维度定为 15%。国际教员比例占 5%，国际研究网络占 5%，国际学生比例同样占 5%。同一栏里还有一个国际学生多样性，权重写着 0%。三个 5% 加起来就是这 15% 的全部。学生常把这一栏当成锦上添花，其实这些指标的档位与师生比、可持续性属于同一量级。所有权重的复核是每年一次，具体数字以 QS 官网当季的方法论页为准。
The Global Engagement lens is worth 15 per cent of the overall score. Inside it, International Faculty Ratio, International Research Network and International Student Ratio are set at 5 per cent each; a fourth indicator, International Student Diversity, sits in the same table at 0 per cent. Those three fives are the whole lens, and the weighting is reviewed once a year on the QS methodology page.
国际教员比例的定义与公民身份口径
QS 官网把国际教员比例定义为国际教员人数占全体教员人数的比例。判定是否国际只看公民身份，不看出生地，也不看本科学位在哪读。欧盟国家之间的口径更宽，其他欧盟成员国的国民同样被算作国际教员。香港特别行政区的口径相反，来自中国内地的教员被算作国际教员。任教时长的门槛写在定义里，每年至少三个月从事教学、研究或者两者兼有。只在暑假来开一门讲座的老师不满足这条，不会被计入分子。访问性质的国际教员另有排除条款，那些人隶属另一所大学，哪怕外籍也不算这所学校的国际教员。
The ratio itself is straightforward: international faculty staff divided by total faculty staff. What counts as international is decided by citizenship rather than birthplace or where a degree was taken. For EU countries every foreign national qualifies, including nationals of other EU states, while in Hong Kong SAR staff from mainland China are treated as international; teaching or research for at least three months a year is required, and visiting staff who belong to another university are excluded entirely.
双国籍、访问学者与第三方数据核对
双国籍的情况 QS 也给了判据，以出生取得的国籍或者第一本护照为准。这条规则对跨境任教的学者影响最直接，一位持两本护照的教授在不同学校可能被记成不同的国籍。访问学者被排除在外的理由很实在，QS 要衡量的是这所学校自己招到的国际教员，而不是借来的名字。数据来源分两条线，一条是院校在调研过程中自己提交的材料，另一条来自第三方，包括政府部门与公开网页。QS 官网写明，能交叉核对的地方都会用多个来源核一遍。这个指标不只服务世界大学排名，亚洲、阿拉伯地区、欧洲几个区域排名与商科硕士排名都在用它，那边的权重普遍更低，多是 2.5%。
Dual nationals are judged by citizenship acquired through birth or by the first passport obtained, a rule that matters most for academics who move between countries. The three-month definition plus the exclusion of visiting staff both push the indicator towards people the institution has actually recruited; data arrives partly from institutional submissions and partly from third-party sources such as government ministries and public web pages, which QS checks against one another. The same indicator also appears in the Asia, Arab Region, Europe, Global MBA and Business Masters projects, where it usually carries 2.5 per cent.
国际研究网络的官方公式
国际研究网络的算法在 QS 官网的指标页上写成一条公式，不同国家或者地区数除以国际合作机构数的自然对数。分子看的是广度，也就是这所学校的研究伙伴分布在多少个不同的国家或者地区。分母取对数，为的是压住合作机构数量的自然膨胀，一所学校和两百个机构合作，并不会自动比和五十个机构合作的学校强四倍。这条设计针对的是规模效应，研究产出大的学校合作机构名单往往长得多。真正被奖励的是把合作铺到更多国家，而不是把同一批伙伴的合作次数堆高。这也是新入榜院校能在这个指标上表现突出的原因之一。
The calculation on the QS indicator page takes the distinct count of countries or territories and divides it by the natural logarithm of the distinct count of international partners. Countries measure reach, while the logarithm dampens the advantage that comes from a longer partner list; a university working with two hundred partners is not four times stronger than one working with fifty. Spreading collaboration across more countries counts for more than repeating the same partnerships, which is one reason newly ranked institutions can score well here.
持续合作门槛：五年三篇合著论文
只有持续的合作关系才被计入，QS 的门槛是五年之内三篇或者更多合著论文。一次性的会议论文或者单篇合作不构成网络。这条门槛把学术人情式的挂名过滤掉，留下的关系是双方反复续订的。合著关系的判断依赖文献计量数据，而不是院校自报的合作名单。合作关系能否续订也很关键，QS 官网明确说它同时看这些关系有没有被更新和重复。底层数据来自 Elsevier 的 Scopus，那是由独立学科专家维护的摘要与引文数据库。这层数据门槛决定了国际研究网络不太容易被短期操作影响。
Only sustained partnerships count, defined as relationships producing three or more joint papers within a five-year period. A single conference paper or one-off collaboration does not build a network, so the threshold filters out courtesy authorship and keeps relationships that both sides renew; QS states explicitly that it looks at whether those relationships are renewed and repeated. The underlying data comes from Scopus, the abstract and citation database curated by independent subject experts at Elsevier.
五个学科领域的标准化与 z 分数
计算之前，论文会先按五个学科领域切开。QS 的做法是在每个领域内部先把数值按极值标准化到 1 到 100，再取五个领域的平均值。平均值之后再套一层 z 分数标准化，最后重新缩放成可比的分值。这套流程让不同学科体量的学校站在同一条线上，医学院庞大的学校不会因为论文总量大就自动占优。学科之间合作习惯的差异也被这层处理吸收，人文学科的国际合著本来就比理工科少。QS 在学科排名里不执行前面的标准化步骤，只做 z 分数与重缩放。
Before scoring, papers are split across five faculty areas. Within each area the raw values are min-max normalised onto a 1 to 100 scale, the five areas are averaged, and a z-score normalisation is applied before the result is rescaled. That sequence stops large medical or engineering faculties from dominating on sheer output and absorbs the different collaboration habits of arts and science subjects; in the subject rankings the earlier standardisation steps are skipped altogether.
两个指标放在全球参与而非研究类的原因
国际研究网络听起来像研究指标，位置却在全球参与这一栏。这样安排有它的道理，它衡量的是合作的广度，不是研究质量或者引用影响力。引用表现已经由单位教员引用这一指标承担，权重 20%，属于研究与发展那一组。把国际合著单独放进全球参与，避免了同一批论文数据被重复计分两次。国际教员比例归属同一栏的理由也类似，它反映的是这所学校对外籍学者的吸引力。两个指标都指向同一件事，就是学校与外部学术世界的连接方式。
International Research Network sounds like a research measure, yet it sits under Global Engagement. It tracks the breadth of collaboration rather than research quality or citation impact; citation performance is already covered by Citations per Faculty, weighted at 20 per cent under Research and Discovery. Keeping international co-authorship in a separate lens stops the same publication data being counted twice, and International Faculty Ratio sits there for a similar reason, since it reflects how attractive a university is to academics from abroad.
权重表里 0% 的国际学生多样性
方法论页面的权重表里有一行容易被看漏。国际学生多样性与国际学生比例并列出现，权重写着 0%。这意味着它目前不进入总分计算，只是作为观察项挂在同一栏。学生查排名时如果看到这一项，不必按 5% 去估算它的影响。真正的第三个 5% 是国际学生比例。同一个页面上还写着，全球参与这一整栏的权重也是逐年复核的，所以 0% 是当季设定，不是永久安排。
One line in the weighting table is easy to miss: International Student Diversity appears alongside the others at 0 per cent. It therefore adds nothing to the total score and works as a reference figure rather than a scored indicator, so anyone estimating the effect of internationalisation should look at the third 5 per cent, International Student Ratio. QS also states that weightings are reviewed annually, which makes the zero a current setting rather than a permanent one.
5% 换算成总分与名次浮动的量级
5% 在总分里是什么概念，把它和就业结果放在一起看最直观。就业结果同样占 5%，与第三个国际类指标权重相等。一所学校在一个指标上拿到满分，换算下来就是总分里的 5 分，两个指标都拿满分相当于 10 分。2027 版第一名总分是 100 分，并列第二的两所是 99.2 分。不到一分的差距足以让一所学校挪动好几个位置。这也解释了为什么同一所学校在不同年份的名次会出现几位的浮动。
Five per cent is easier to picture next to Employment Outcomes, which carries the same weight as the third international indicator. A perfect score on one indicator is worth five points of the overall total and two perfect scores are worth ten; the 2027 leader finished on 100 and the joint second place on 99.2, so a shift of less than one point can move a university several places. That is why the same institution drifts a few positions from one edition to the next.
新入榜院校在国际研究网络上的表现
2027 版有 98 所院校首次入榜。多数新入榜院校落在 1,000 到 1,500 这一带，其中位次最高的 Central European University 排在第 239。QS 的公布文案里有一句很值得留意的话，新入榜院校在入榜时最强的平均指标就是国际研究网络。一所规模不大的学校只要合作关系铺得够宽，就能在这个指标上超过体量大得多的对手。分子只看国家或者地区数量，不看论文总量，这条规则给了小学校机会。国际教员比例对新入榜院校的作用没有这么明显，它要拿全体教员做分母。
Ninety-eight institutions entered the 2027 ranking for the first time. Most of them landed in the 1,000 to 1,500 band, with Central European University the highest new entrant at 239; QS notes in its own announcement that new entrants perform best on International Research Network, their strongest mean average indicator at entry. Because the formula counts countries and territories rather than total publication output, a smaller university with broad partnerships can beat institutions many times its size, whereas International Faculty Ratio offers less of that shortcut since the whole faculty forms the denominator.
常见误读：国际教员比例不等于英语环境
把国际教员比例当成英语授课环境的代理指标，是查排名时最常见的错误。公民身份判定的是护照而不是教学语言，一所国际教员比例很高的学校完全可能主要用母语授课。另一个误读是把它当成教学质量的证明，这个指标描述的其实是招聘结果与工作场所的吸引力。很多学生以为这一项分数低就说明学校不够国际化，实际上本国学术劳动力市场的规模、签证与移民政策、薪酬竞争力都会直接改变分子的数字。看这一项更实用的做法是拉出学校近三年的数据，看趋势而不是看单年名次。国际研究网络同理，它说的是合作版图，不是研究成果的好坏。
Reading International Faculty Ratio as a proxy for an English-speaking campus is the usual error. Citizenship is about passports, not teaching language, so a university with a high ratio may still teach mainly in its own language; the indicator describes recruitment and how attractive a workplace is rather than teaching quality. Many students assume a low score means a university is not international, yet the size of the domestic academic labour market, visa rules and pay competitiveness all move the number, which is why three years of data tell you more than a single rank.
选校时这两个指标怎么用
选校时把这两个指标当成两个问题来看更省事，一个问这所学校从哪里招老师，一个问它的研究合作铺到哪些国家。打算走研究路线的学生可以从国际研究网络反推实验室的国际连接。QS 官网要求合作持续到五年三篇合著论文，这条门槛本身就筛掉了临时拼凑的合作。关心语言环境的家庭可以拿国际教员比例当参考，但要配合授课语言与当地移民政策一起看。三个 5% 的指标都没有涉及教学质量与学生体验，那属于师生比与学习体验那一组。名次之外的这些细节，往往比名次本身更有参考价值。
For choosing a university these two indicators answer different questions: where the staff come from, and which countries the research partnerships reach. A student heading for research can read International Research Network as a map of a department's international links, since the five-year, three-paper threshold rules out temporary arrangements; families worried about language can start from International Faculty Ratio but should check teaching language and visa rules alongside it. Neither indicator says anything about teaching quality or student experience, which sit in the Learning Experience lens instead.
