Two body problems are real. Maybe if you are just employing kids, but your spouse probably works somewhere else.
China still has company towns for some SOEs (not even for migrant workers, regular well payed Chinese professionals), but these are usually outside of cities and are more like gated communities. The last time I visited one in Hunan near Leiyang, we had a nice meal at the company restaurant (not the only one). Not really for software-based high tech, where talent accumulation demands central city placement. Heck, they still try putting R&D centers out in the far off suburbs (Microsoft's Zizhu campus in Shanghai) and there is a lot of push back (better to work at Microsoft's more centrally located Beijing campus).
