Abstract: Beginning with the per capita disposable income, uses the method of income distribution function fitting to establish corresponding relationship between income and population proportion, and then calculates the population who have to purchase commercial housing to meet the housing needs. In the end, this paper puts forward the new housing price to income ratio formula, on the basis of improved one, to compute the affordable commercial housing price range for residents.

Key words: commercial housing price; price range; indemnificatory housing; income distribution function fitting; housing price to income ratio formula
