Preface: I am just another ignorant westerner. Any one of my impressions of these countries could be so wrong as to make my conclusions meaningless. If I'm wrong, please be gentle.
I believe there's some differences of scale here. China and India both have over a billion people. With 10x the population of Nigeria, even with identically bad property rights and legal systems (and I suspect that both India and China are somewhat better off in that regard than Nigeria), with that difference in addressable market you'd expect more startups out of them.
Russia -- which has a shrinking population now roughly the same as Nigeria's rapidly-expanding one -- is a more interesting comparison. I think the only difference here is that Russia was formerly a wealthy country (as opposed to a country in which a few extremely wealthy people live) which invested heavily in education, while Nigeria is a formerly poor one that has yet to catch up.
So if Nigeria were to suddenly pour as much money into education as the USSR did, you might expect a flood of Nigerian startups in a decade's time. But that would explain why there aren't too many of them right now.
