This paper researches the relationships between sub-center cities, satellite cities and core cities in Jingjinji Area, Huninghang Area and Pearl River Delta. It also covers the connections between Chinese housing market and stock market. It uses an unique dataset called China Real Estate Index System (CREIS) to measure the Chinese housing prices. Through correlations, Granger causality tests and regression models, this paper concludes there are indeed connections for the movements in housing prices in the surrounding cities relative to Beijing, Shanghai and Shenzhen in the three city groups, and there is no sufficient evidence to show the existence of the connection between Chinese housing market and stock market.
