| Abstract: | With the help of the data of the years 2001~2010,a mathematical model of commercial housing price changes in Lanzhou is established:Zt=p2t2+p1t+p0.A multiple linear regression equation of commercial housing prices is also analyzed:log Z=C0+C1log(N1)+C2log(N2)+C3log(N3)+C4N4.Four main factors including population,average investment cost of real estate agents,per capita income,one-year deposit interest rate are considered.The results show that price of commercial housing is a quadratic non-linear growth with ... |
