What is the difference then? Willingness to work for lower wages? Greater determination? State subsidies? It's not like Chinese universities have a great reputation en masse. It's also clearly not IP theft (alone) since they are the leader - who would they steal from?
If it's subsidies, then China must be taking the subsidy money from somewhere. It's not, as I understand, a non-social, cutthroat capitalist country. Retirement age is something like 55. Is Chinese hegemony in battery production effectively subsidised by underpaid peasants? But surely the image of guys in sloping hats rolling rice paddies desperately outdated; I don't expect Chinese farming to be behind European in terms of technology.
So if it's subsidies, then where is the money coming from, that European governments clearly don't have?
