Application of GIS and Gradient Shift Theory of Residence Remise Land Price in Beijing

Understanding the spatio-temporal distribution of remised land prices of a large city is important in formulating macro-controlling strategies of estate prices.The theory of gradient shift in regional economics combined with GIS technique is used to investigate spatio-temporal features of remised land prices(RLP) of Beijing.The results revealed that remised land price exhibit a high spatial correlation and the effect of regional factors on land price was more important than that of stochastic factors.High RLP regions were mainly located within second-ring road in 2001-2004,while in 2005,it shifted to outside second-ring road,2007 to outside third-ring road,2008 to outside fourth-ring road and 2009 to outside fifth-ring road.The area outside fifth-ring road will be the centre of residential development.The above gradient shift of land prices over the last ten years might be intimately associated with land supply of urban areas,construction track transportation,infrastructure,and shift of functions of downtown areas.
