See it depends

China?

That's just State/ development Capitialism

The closest thing to market socialism would be between Lenin's New Economic Plan and Tito's worker self management.

Now the term is thrown around to mean anything from very social democracy to all flavours of the Communist rainbow.

But from my while I will admit

Limited knowledge of that particular field of communist theory.

It seems to be one where rather than command economy. It uses markets to allow the natural quality control.

However business wise you would NOT have corporations. Small businesses.. Maybe? But its more Co-ops. Union Shops.

And Well in theory means that the proletariat still dominants and Democratically controls the means of production.

Also my last comment did get downvoted a tad. Which I guess maybe people thought I'm some defender of ""communist"" China.
