There is an interesting new paper out from Jing Wu, Joseph Gyourko and Yongheng Deng on the Chinese housing market. The FT covers the paper here. The headline number of 800% growth since 2003 jumps off the page.
Although the paper doesn't go so far as to declare this a bubble - I discussed the Chinese housing market with Prof. Gyourko a few months ago - his take "a bubble - no question."
Looking at these data I would have to agree.
