Research On The Effect Of Urban Public Service Facilities Accessibility On The Spatial Differentiation Of Housing Price

At present,many cities in China are in the fast stage of urbanization.In the process of urban renewal and expansion,real estate market of China is booming,at the same time,the spatial mismatch between supply and demand of urban public service facilities and the differentiation of housing price are increasingly prominent.Urban public service facilities,as the basic factor determining the living quality of residents,have become key resident attractors of different locations residents.The spatial distribution pattern of these resources dominates the formation and evolution of the urban housing price space by influencing homebuyers when choosing their residential locations.Under the screening mechanism imposed by housing prices,the rich undoubtedly win in the competition for residences with accessibility to first-class education or water resources.Taking Xi'an as a research case,based on the perspective of urban resource space allocation,this paper explores the effect of accessibility of public service facilities on housing price differentiation.This paper uses spatial analysis tools of Geographic Information System(GIS)to describe the spatial distribution pattern of housing prices and urban public service facilities.Using the mixed geographically weighted regression model(MGWR)and the geographical detector model,this study reveals the spatial effects of these facilities' accessibility on housing prices.The results show that commercial and leisure facilities are spatially stationary,whereas a non-stationary effect is observed among those providing educational,medical,cultural,sport,and financial services.Based on the perspective of urban spatial resource allocation,the public service facilities that meet basic needs of people,such as medical and educational facilities,are the basic elementsof housing price differentiation,and the interaction between the two has a bivariate-enhanced effect.while the public service facilities that meet high-level needs of people,such as leisure,cultural&sports facilities and financial facilities,are important interactive elements of housing price differentiation,which have a significant effect of non-linear enhancement on other facilities through interaction.The paper puts forward relevant suggestions from the perspective of urban resource spatial allocation and housing supply.On the one hand,government should pay attention to the balanced allocation of facilities,such as schools and hospitals,which meet basic needs of people,effectively playing its fundamental role in the differentiation of housing prices,then,optimize the spatial distribution of facilities,such as parks and leisure squares,which meet high-level needs of people,to avoid the destructive effect of the interaction of the two kinds of facilities.;on the other hand,it is recommended to increase the supply of affordable housing for low-income people in the urban superior area.The research has important practical value for improving the living quality of residents,optimizing the spatial layout of public service facilities,improving the imbalance of urban space,and maintaining the sustainable development of social space.
