Research on the Spatial Matching of Affordable Housing and Public Service Facilities in Chengdu, China

Under the realistic background of the layout of public service facilities, which is capitalized into the house price to some degree, it's a key point for government to insist on the harmony between efficiency and safeguard of social fairness, and it's also a significant standard of affordable house to live comfortable or not. This paper, based on the field survey of the construction scale and spatial distribution of affordable housing construction projects in Chengdu from 2007 to 2014, evaluates the accessibility of affordable housing to five types of public facilities used by ArcGIS. Through the study of the shortest distance with ArcGIS, the results of this paper show that, firstly, the availability ranking of affordable housing to public service facilities is green land, subway, key secondary school, business center, Class A&B Hospital. Secondly, from the point of fair value, the difference in the spatial layout of affordable housing and public service facilities, leading to the inequality of accessing to certain public service, it will be more unfair for the accumulation of affordable housing's construction. Thirdly, the basic public service is fair obtained even in Chengdu's cluster area of affordable housing, while the unequal characteristics of high quality public service are obvious at the same time.
