China has poor house price statistics. The National Bureau of Statistics of China (NBSC) has monthly house price time-series starting January 2011 but only until August of 2013. Another source of house price indices is eHomeday, Shanghai's largest property market web site, which has time-series for Shanghai, Nanjing, Hangzhou, Beijing, Yangzhou and Suzhou (but the site is only in Chinese, and no time-series are available). Colliers International publishes useful housing data in their quarterly property market reviews. General economics statistics are available from the NBSC and the People's Bank of China.
