Research On The Mechanisms Between Urban Form And Urban Public Services Expenditure And Policy Design

It has important theoretical value and practical significance for the realization of urban sustainable development and equalization of public services expenditure to explore the difference of public services expenditure among cities and the potential influence mechanism of urban form on urban public services expenditure.Firstly,this paper summarizes the situation of public services expenditure in China and makes a comparison among 30 cities from both the level and structure of public services expenditure.In addition,the method of standard deviational ellipse is used to analyze the spatial and temporal differences of urban basic public services expenditure.Finally,with the help of remote sensing and Geographic Information System,we select urban compactness and urban elongation as urban form to accurately describe urban development pattern.And data of urban public services expenditure is collected from authority database.Panel data regression model is adopted to analyze the mechanism of city morphology effects on 10 kinds of public service expenditure type.The results are as follows:The urban public services expenditure in China is increasing year by year,and the gap of the gross of public services expenditure among cities is gradually widening.Local governments regard education and urban and rural community affairs as the main expenditure items.The proportion of general public services expenditure to fiscal expenditure is decreasing and the proportion of environmental protection is increasing and the other items remained stable.The eastern city is the main area of basic public service expenditure and potency dimension of public services expenditure of western cities is increasing.The difference between the spatial distribution of urban basic public service expenditure and the spatial distribution of population is narrowing.Urban compactness is rising and urban elongation is declining in China.Chinese cities are undergoing a compact development pattern.Urban elongation ratio had significant positive correlation with 7 types of urban public services expenditure and had no correlation with other 3 types.On the other hand,there is no significant correction between urban compactness and public services expenditure,which means that change of urban compactness does not lead to the change of public service expenditure.But city elongation increases public service expenditure increase.Based on the above conclusions,it is suggested that the expenditure of basic public services in central and western cities should be further increased.Besides,Chinese cities should take the compact development path with the control of city sprawl in order to enhance the efficiency of public service expenditure and reduce unnecessary expenditure of public service to realize the equalization of public service.
