Your question is asking something other than the obvious. Could you explain more?<p>"The obvious" is to look at how your state or country handles city incorporate. In the US that's at the state level.

A DDG search for 'China "new city"' finds many links.<p>There have also been many created cities.

The “New Cities” initiative will study freshly minted cities, and how to plan, design, and build them from scratch.<p>I'm sure you could find more scholarly references in Google Scholar using similar keywords.
