Study On Risk Assessment Of Public Rental Housing Project Under PPP Model

Public rental housing is a kind of welfare housing built by the government to solve the housing problem of low-income people in urban areas.Under the traditional mode,the construction funds for public rental housing projects are mostly financed by the central government or local governments,and the financing channels are single,with one-time investment.Introducing the PPP model into the construction of public rental housing projects will not only ease the pressure on government financing,but also adapt to the general trend of the times.There are many participants in the public rental housing PPP project,and the risk factors are complicated.The government is in a dominant position and the social capital faces a greater risk challenge.Therefore,in-depth study of the risks involved in social capital can ensure the successful use of the PPP model in public rental housing projects.Based on the perspective of social capital,this thesis uses the risk management theory and the example of Xianghe Nanyuan PPP public rental housing project to do the following work for the risk management of public rental housing PPP projects:Firstly,this thesis expounds the related theories of PPP financing mode,public rental housing project and risk management,analyzes the connotation and characteristics of public rental housing and PPP mode.On this basis,the feasibility and social capital of PPP mode applied to public rental housing projects.The party’s basic interests appeals were analyzed.Secondly,using the literature analysis method to summarize the risk factors of the PPP public rental project during the whole life,and finally form the risk in the planning and design stage,the pre-construction preparation stage risk,the construction stage risk,the operation stage risk and the coexistence risk of each stage.A total of 5 stages of risk,and build a preliminary identification list of risk factors.Based on this,the data mining association rule algorithm is used to set the support threshold to achieve the screening of the preliminary identification risk factors.According to the special application of the public rental project The brainstorming method supplements and revise the screening list of risk factors to form a final risk factor identification list,making the riskidentification process more scientific and reasonable.Thirdly,based on the construction of risk assessment index system,the improved TFAHP method is used to determine the weight of each index,and the two-dimensional cloud model is used to comprehensively evaluate the risk equivalence from the two dimensions of risk occurrence and risk occurrence.The concept of further precise risk levels in mathematics.By expounding the process and principles of risk sharing,combined with the results of risk assessment,the utility theory model is used to share the risk between the social capital party and the government department.Finally,taking the Xianghe Nanyuan PPP public rental housing project as an example,the theoretical method of the thesis is applied to the example to evaluate the risk status of the whole life.And through the setting of the confidence threshold in the data mining association rule algorithm,the correlation rules between risk factors are obtained.On the basis of strong association rules,specific risk control measures are given.The research results of this thesis enrich the PPP project risk management theory and provide some reference and support for the social capital of the public rental housing PPP project during the whole life of the project to ensure the smooth progress of the project.
