Risk Assessment Study Of Shanty Town PPP Transform Project

Shanty town is a historical issue in our country,which has seriously hindered the modernization and urbanization of our country.Shanty towns transformation has become the urgent problem which need to be solved.Western countries has applied the PPP model to various kinds of infrastructure construction and achieved good results.The application of PPP model can well solve the government’s pressure and effectively use of social idle funds of funds,which makes both parties to achieve win-win results.However,due to the shanty town PPP transform project has many participants,the complexity of the project,the characteristics of the risk factors,the view of the shanty town PPP transform project risk study is less,and the private sector may be unclear about risk factors,which leads to the failure of the project,So the private sector are reluctant to participate in the shanty town PPP transform project.In order to mobilize the enthusiasm of the private sector,make it profitable and achieve the objective of the project to participate in the two sides reached a win-win situation,to the management of the risk in a reasonable manner.On the basis of related research at home and abroad,this paper introduced the basic concept of PPP mode and the shanty town transformation,the development present situation,and analyzed the feasibility of PPP model applied in shanty towns transform project,made the brief elaboration of the common cause failure theory and uncertainty and sensitivity analysis theory,which made the foreshadowing for the introduction of the risk assessment method.This paper uses the WBS-RBS method to identify the specific risk factors of the shanty town PPP renovation project and build risk evaluation index system based on it,and uses the improved ISM-FCEM to evaluate the risk.First of all,using the ISM method to analyze the interaction relationship between risk factors and get the risk hierarchy structure.Then,build multi-dimensional function from the perspective of the four dimensions of risk,and combined with the ISM risk analysis results to score the risks,determine the risk factors’ weight,then calculates comprehensive risk degrees of the project.According to the weight value of each risk factor to the overall goal based on the improved ISM-FCEM method,the private sector can be more reasonable for risk analysis and management.Finally,this paper makes an empirical analysis,verify the operability of the model,and provide certain reference for the risk assessment of shanty town PPP transform project.
