November 2,2014,the Department of Housing and Urban Construction Department of Housing Construction and Urban Construction Division in 2014 points "in the proposed"Sponge-type City concept,also released the Sponge City construction technology guide-low-impact development of rainwater system construction Trial,for the new urbanization around the city sponge building provides guidance.The construction of the sponge city is to build the perfect rainwater management system facilities in the city to solve the ecological environment problems,such as flood disaster,runoff pollution,rainwater resource loss and ecological environment destruction.The establishment of 16 pilot cities Sponge City construction,the pilot cities are sponge city planning and construction invested heavily,ranging from a few billion dollars,as many as tens of billions of dollars,construction funding gap more and more obvious,how to solve the Sponge City Construction funds become a bottleneck restricting the development of sponge city construction.At present,the construction fund of sponge city mainly comes from the government financial subsidy.With the increasing demand of sponge urban construction funds,the government financial subsidy is far from satisfying its needs.The main problems in the research of the Sponge City is how to seek new financing mode,and how to introduce social capital to participate in Sponge City construction.This paper firstly analyzes the current situation of domestic and foreign construction of sponge city,the related theoretical research and the research of PPP model risk.Through the analysis of the policy,Sponge City construction and PPP financing mode,the feasibility and necessity of applying PPP model in sponge city construction are obtained..As well as the current Sponge City construction which problems.Secondly,combined with Sponge City construction project application scope,construction technology and other characteristics of complex construction technology and operational facilities of the theoretical basis,analysis of the different carrier sponge city project profit model.It is concluded that the PPP project in Sponge City has strong externalities,and reasonable operation mode and investment income mechanism are suggested according to different project types.Finally,based on the relevant research,this paper puts forward the risk identification of the PPP project in the Sponge City.Through the interview questionnaire and other forms,the expert scoring is obtained and the main risks are identified.According to the fuzziness of the evaluation language,fuzzy analytic hierarchy process(FAHP)is used to construct the risk-sharing index according to the principle of risk-sharing and calculate the project financing participation in the main government departments and private enterprises.Financial institutions in the face of different types of risk,according to their own characteristics with the experts to determine the proportion of the proportion of scoring for the Sponge City contract and reasonable risk aversion to make recommendations.
