This building is supposed to have a mix of low and high income housing (how does that work?) as well as schools and other social services. Given that space in China is not at a premium I don't think you can call this anything but a social experiment. Maybe if it works they can export it to HK where it might actually be useful. (Though it does conjure images of a sort of neo-Walled City.)
Given that this type of construction produces boring, utilitarian space I don't understand why they're not using it for offices. I imagine this would be much more tolerable as office space and the footprint / usable space ratio would make sense for commercial districts.
