It's not that productivity growth is unimportant - it's in fact central to progress - just that TFP is a very poor measure. It was created in the 1950s when all we had was either farms or factories. It is not updated to the modern world.
I prefer to look at labour productivity instead, and China is still seeing fast rises since labour growth is either zero or even negative, that means that all GDP growth has to come from productivity gains in labour by default now that the infra boom has ended.
I've long noted that China's industrial prowess is fantastic. It's really the service sector it needs to pay closer attention to. However a comparably weak service sector seems to be a recurring theme among East Asian economies (you see the same thing in Japan, Korea, Taiwan etc). Perhaps it won't matter too much.
