Discussions of why China has fewer startups than the United States have an invariable financial sector component. That's my entire point. Not that the US financial sector is perfect.
Do you have any really reliable data on these startups?
1) on how startups are counted
2) how long they are around
3) promising startups that are looking for money, but can't get access to money
There are always ways that you can improve the Chinese economic structure. But given its successes, the areas of improvement may not be where you think they are.
