Democracy is good when its good, and okay when its bad.
Democratic system are never the fastest way of getting something done, but seems to be the most consistently less-bad system for outcomes. The state that can build an entire medical infrastructure from scratch is also the same one that can build vast concentration camp systems far out in the provinces.
"These policies led to social and economic disaster, but these failures were hidden by widespread exaggeration and deceitful reports. In short order, large resources were diverted to use on expensive new industrial operations, which, in turn, failed to produce much, and deprived the agricultural sector of urgently needed resources. An important result was a drastic decline in food output, which caused millions of deaths in the Great Chinese Famine."

Sure, they'll not make that mistake again - but they'll make others just as egregious. It's what authoritarians do best.
That's ironic given China's vaunted ability to think very long-term (100-year strategy).
If you do not follow that culture, your business, if successful, will be virtually and very quickly devoured by lawyers or partisan politicians seeking their racketeering tax.
Both of those professions essentially became licensed racketeers in the Western world.
I would also build up on your premise, and say that it is not that China is advancing at incredible pace, it is that our own West Europe and US have been slowed down by the above internal nemeses.
So, if you’re a politician or a big businessman, you can say whatever you like. We have a 3 year plan to eradicate X. We will completely redevelop the entire southern sector of the city and everyone will be rich and happy. And we’ll do it in 2 years.
China does a lot and achieves a lot, but for example, each time you read something China related in the news, check how many times it says “China plans to....” or “Government announces plan to.....”
