It’s arguable whether China actually benefited from an authoritarian, centralized economic model or from other factors. They did open up their society to market economic forces, both domestic and international, although they do seem to be ready to pull the rug out from people at a moment’s notice - for example with banning some foreign company or with blocking IPOs or disappearing business leaders. Another factor is the literal theft of intellectual property through corporate espionage or hacking, as well as the theft of IP through business relationships (for instance with European high speed rail manufacturers). I do think China’s leadership, particularly Xi Jinping, still have an eye on implementing an idealistic socialist/communist system as an end goal, but it does seem like all the steps to get there involve anything but that.
