Not really a detailed explanation but when I was there a few months ago the guy I was with said that a lot of them were sitting around unfinished because they didn't have any buyers. A lot of them are so called luxury buildings where I'm sure the developers don't want people who can't afford that type of life living, they were pointing out buildings where apartments were 1.5M RMB ($250k) which given the wages in China is just a bit ridiculous. The factory I was visiting was constantly complaining about how nobody wanted to work in the south of China anymore and that all the workers had moved up to Shanghai, yet there was all this construction and plans for huge growth in the area. I just couldn't figure out how they were justifying these plans.
