Risk Management Research Of PPP Project In China's Sponge City

In recent years,more and more Chinese local governments and social capital cooperate with PPP model to participate in the sponge cities construction.And it has become the focus for cities all over the country which are trying to make accelerate the construction of new urbanization according to the "steady growth,promote reform,structural adjustment,favorable to people" policy core.With its' characteristics of “sharing risks and benefit,whole process cooperation”,PPP model could transfer some parts of responsibilities from the government sides to the social capital sides by the way of franchise.While reducing the government's financial burden and investment risks of the social investors,PPP model also play an important role to promote economic and social development in the world,especially in the fields of public utilities,natural resources construction and operation.Sponge cities means to make cities construction and operation plans through the ways of “infiltration,retention,storage,purify,application,runoff” and other engineering technology to control urban rainwater management.As the sponge cities' construction and operation always requires complex projects,huge investment,long term process,PPP model may become the most suitable match.However,due to the complexity of sponge cities' construction and management,how to prevent the risks effectively,in order to ensure the quality and efficiency of the project under the conditions of the effective implementation of PPP model is still a new issue.This paper starts with the study of PPP model and its risk,draws lessons from the case of some foreign countries,discusses the main problems and obstacles in the process of propulsion of sponge cities PPP projects.While,the author also finds an example of S Sponge city PPP project,analyzes the risks existing in it,and tries to put forward some precautions,then also tries to put forward some points and suggestions,such as to further improve and perfect the top design relevant government policies and regulations,clear the overall project planning and packaging in liability attribution,establishing the project financing and revenue model standards,abide by the agreement of the performance evaluation and assessment for Chinese sponge city PPP model's risk management,hope which could be helpful and useful for the future Chinese sponge cities' PPP projects implementation and risks control.
