The premium effect of public service facilities on the housing market is a critical determinant of housing prices, leading to the competition of different social groups in the housing market and fueling spatial inequality. Taking Xi’an, China as a case in point, this study uses 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 (GD), 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. From the urban spatial resource allocation perspective, facilities meeting people’s basic needs, such as medical care and education, constitute the basic elements of housing price differentiation. When any two of these interact, a bivariate-enhanced effect emerges. The decisive interactive elements of housing price differentiation involve the facilities meeting people’s higher-level needs, such as leisure, culture, sports, and finance. When these interactive elements interact with other facilities, a non-linear enhancement effect is induced. This research is of practical value for improving people’s living quality, optimizing the spatial distribution of public service facilities, and eliminating urban spatial inequality.

Currently, the Chinese government leads urban renewal via a top-down management style with the government playing the role of decision-maker. The decision-making opinions held by groups of stakeholders are divided, which creates many social problems, project technical issues and even civil disorder. This paper uses factor analysis to extract the key variables for decision-making on urban renewal and the entropy weight method to sort these key variables by importance. Based on this order, the differing opinions of stakeholders regarding urban renewal decision-making are explored. First, contradictory opinions exist concerning the importance of the ecological environment, housing and facilities, social welfare and commercial activities, which are the main driving forces behind urban renewal, due to the groups of stakeholders having different interest demands. Second, these varying interest demands of the stakeholders affect the urban renewal decision-making results. Finally, compensation to people for the demolition of their homes, infrastructure supplements and the investment behaviour of developers display the greatest lack of consensus of all the variables tested in urban renewal decision-making between different stakeholders.
