The Study of Spatial Characteristics of Urban Land Price and Its Influencing Factors

Immovable land has spatial heterogeneity. This study first analyzes the theoretical models of urban land prices based on the analysis of its spatial differences, and then analyzes the difference of urban land price influencing factors between different areas by Geographically Weighted Regression Model. The results indicate that:(1) from national scale, there is spatial autocorrelation of land price between cities, and also urban strengths and urban land needs have positive influence on urban land price, and urban land supply has the negative effects;(2) from regional scale, urban land prices are affected by the surrounding urban land market and land prices, and also the influencing factors have spatial differences;(3) the factor of per capita disposable income of urban residents have great impact on urban land price in three major megalopolises, but the rest factors are different in different regions.
