Study On Matching And Assignment Model Of Public Housing Based On Demand Perspective

Housing security is a sum of policies and measures carried out by the government, the purpose of which is to support urban residents with housing difficulties to meet their basic housing needs. It is the policy guarantee to solve the urban housing problem and reach the goal of "housing everyone". This research focus on urban residents housing needs and choice, housing security object segmentation and the matching assignment of public housing, and the research questions are as follows:1) To identify the housing needs through the attributes of urban residents.2) The influences of urban residents’attributes to the willingness of improving housing condition and housing choice.3) The study on housing security object segmentation and public housing matching assignment method based on housing needs under the housing security policy. To investigate the above questions, the main work and contributions of the thesis are as follows:First, the research divides the urban residents’attributes into "demography" and "current housing condition" based on literature review and the housing investigation questionnaire, and constructs the urban residents housing needs identifying indexes and model. Using2142random samples of housing investigation, five most important attributes for housing needs identifying are filtered through the attribute reduction method, and the characters of urban residents with different housing needs are analyzed based on modified diversity fuzzy k-protype clustering method.Second, based on88793samples of housing investigation and the indexes of housing needs identifying model, a Logistic model to analyze the influence factors of the urban residents’willingness to improve housing condition is proposed, and the influence of "demography" and "current housing condition" to the willingness of housing condition improving is analyzed by the Logistic model. Based on the7912samples that have the willingness to improve housing condition, the research studies the influence factors of housing tenure choice, housing policy choice and housing type choice of urban residents when they improve their housing condition.Third, combined with the policy and operation of housing security, this research analyzes the meaning and constructs the indexes of housing security object segmentation. The housing conditions of822new employees are investigated to analyze the demography, housing condition and housing needs of this group. Based on the quantitative statistic of the investigation data, the housing attribute preferences of new employees when renting are aggregated and analyzed, which provides the realistic basis to the public housing assignment of new employees.Finally, based on the analysis of the problem and shortage in the housing assignment literature and public housing assignment practice, the study proposes the description of multi-attribute mathing problem between public security object and publice housing, and several regulations of public housing matching assignment are designed. Referring to the theory of dual-matching, a public housing matching assignment method is proposed based on axiomatic design and excess functionality. A public housing matching multi-objective optimizing decision model is proposed, and the matching assignment solution of the model is solved by membership function weighted sum method. Through the experiment of membership function coefficient, the research discusses the relationship of development stage of housing security, housing security strategy and matching assignment solutions, and some policy suggestions are proposed.
