I don't think that is true. Sure, there is the hukou system, but migrant workers have been free to move around since the 90s, and they do.
If you handed out hukous in 3rd tier economically depressed new cities, I'm not sure if there would be many takers. And the properties in Kangbashi are all fairly high end anyways, the city hukou-deprived migrant workers probably wouldn't even be welcomed.
China builds a lot of subsidized public housing on the city outskirts of major cities, but no one wants to live there because transportation is bad to where the jobs are.
