Ngati, when I ask my colleugue in Greater China desk on what this means (few days after CCP Congress), he said basically on surface nothing changes, just strenghtening what Xi's already done so far.
Common Prosperity as Koxinga put is already common term throughout CCP life time so far, from one leader to another. mutually reinforcing domestic and international market chain is the aim for Xi's Belt and Road Policy. Internal market chain is something that China already work for this last two decades and more since Deng's open up China.
As Mention before in this thread, low wages is not the thing that make China growth exponentially (at least up to Covid). However their abilities to create manufacturing super chain, which in turn means nearly every manufacturing parts sources within China. This is what make China efficient as manufacturing super hub. Something that others like India, ASEAN and other low cost economies (other word on low wages) still not able to copy. This is why despite relocation 'exodus' recently, in truth most still stay in China.
This is why market perplexed and divided on guessing when Xi's CCP going to relax this zero covid policy. Because this policy is the one that can jeoperdise 'internal market chain' that China already build for more than two decades, and still continue as one of their corner stone development goals.
Xi's in some way going to copy on Mao's policy. However I don't think Xi's reign is going to be another Mao's. China CCP from time to time are shaking up their society. We can see that in Tiananmen (as example), which they shake up but then again rebuild toward what they want.
Right now market (can see in many articles in FT, Blomberg, SCMP, etc) already see this COVID being used by Xi's faction as part of their version on shaking up society as well. However too much shaking up, will not be beneficials to what they already built, including their 'Internal Market Chain' mechanism.
China in the end want to depend more on their Internal market. Most big population market done that, US does, even EU also. Thus this is the question on guessing how far Xi's CCP going to balance it.
One thing for sure, you can get substantial fortune if you guess right and bet in correct timing on HK, Shanghai or Beijing market.
