Abstract: As an important index that measures whether the housing price matches people’s income, housing price to income ratio has strong regional characteristics. The housing price to income ratio varies in China’s different cities. This thesis uses the rank-size analysis method to study the major trends of housing price to income ratio of 287 Chinese cities from 2006 to 2010, and then uses the principal component analysis and cluster analysis methods to divide Chinese Cities into five types and analyzes the detail of this ratio in each type city. The result shows that: (1) The differentiation of housing price to income ratio in Chinese Cities shows a trend of expansion from 2006 to 2010, and big cities’ ratios rose more obviously. (2) From the first-tier cities to the fourth tier cities, housing price to income ratio showed a downward trend; (3) Resource-based cities’ housing price to income ratio was between the third-tier cities and fourth-tier cities. (4) Regression analysis shows that urbanization rate had positive influences on housing price to income ratio, but GDP had weak positive influence.
