This question is odd. Do you first mean Singapore as in: “Why does NUS have more PhD students from China than from the local city it is in?”, or “Why does NUS have more PhD students from China than from the country it is in?”
Expressing the question as the former is quite “duh”. Eg, Cambridge University probably has more Chinese PhD students than PhD students hailing from the city of Cambridge. Warwick University probably also has more Chinese PhD students than PhD students from Coventry (yeah, it’s weird how Warwick’s based in Coventry and not Warwick).
In fact, I’d probably say Cornell has more PhD students from NYC (or SF) than home-grown PhD students in Ithaca (the city where Cornell is). Nothing wrong with that if you’re comparing cities.
And I think it’s to be expected, right?
If you do a PhD (with the intent of broadening your horizons / learning more from different people) - do you choose to do it in the hometown you grew up in (group think! same Singaporean mindset!) or do you do it at a different place?
I mean sure - exceptions can be made if there’s faculty that’s directly doing research you are interested in. But in the majority of the cases - doing a PhD in the same town you grew up in doesn’t make sense, unless you view a PhD as nothing special - just something to get it over and done with to get hired - so just do where-ever lor - and therefore more Chinese students than Singaporeans is bad.
So - let’s assume the person asking this question means the second case, i.e. why does NUS have more PhD students from China than PhD students from Singapore.
It’s a case of numbers then? As in the population of China versus the population of Singapore. In fact, we are probably over-represented at top tier universities overseas as PhD students given our small size.
Sure - the number of Chinese students will always be greater than the number of Singaporean students. But given the relative size of China’s population and Singapore’s population? It’s expected.
Just for fun - I looked at the NUS School of Computing graduate students.
http://www.comp.nus.edu.sg/programmes/pg/directory/
and counted 59 Chinese names out of 150 students. So that’s an estimate of about 40% Chinese students - assuming every Chinese name is someone from China.
I picked computing since that’s one of the hot areas now (with Machine Learning and all that).
Does 40% seem a lot?
So I also looked at Cornell University’s CS department - there’s about 45 Chinese names out of 164 students. It’s about 27% - a bit lower than 40% (but consider the fact that Singapore is nearer to China, and we speak the same language).
I also looked at Harvard University’s Statistics PhD programme. About 16 Chinese names out of 40 students. Also about 40% ish.
For Cornell University’s Statistics PhD programme, about 20 Chinese names out of 34 students. About 58%. (I also happen to know who admits these students per year - and the faculty that do so are not Chinese ; so no bias in “selection because same country” there).
Now, I heartily admit I am cherry picking - but I’m picking top tier Universities (maybe comparable to NUS? Or not?) and Departments where the graduates ought to earn high paying jobs (because machine learning! because data science!) - and hence popular with students all over the world.
So if the person asking the question means “Why does NUS have more PhD students from China than from the country it is in?” ; then the answer is: “cause of relative sizes of population - in fact Singaporeans are over-represented compared to the Chinese”. Think about that.
Just to conclude - why don’t we rephrase the original question. Pick a top tier University in the world. Let’s say Harvard.
Then we ask: “Why does Harvard have more PhD students from China than from local Boston?” I guarantee - this question will be met with much more derision.
