Research The Risk Of PPP Projects In The Field Of Urban Infrastructure

PPP (Public-Private-Partnership) as a new type of financing model, its advantage lies in the combination of the advantages of government and social capital. That is,government departments provide policy support and supervision for their projects on the basis of their political status.The social capital is responsible for the financing,construction and operation of the project with its own experience and efficiency in operation management. Ultimately, achieve win-win situation. "13th Five-Year"planning period, China's urbanization will enter the stage of comprehensive development,so that all regions of the country to further increase the demand for urban infrastructure construction. But because the city infrastructure construction has investment characteristics of larger, long duration of operation, investment recovery slow, so that the local government funding for the construction of urban infrastructure and financing more difficult. Starting in 2014, the state has introduced a series of policy documents, encourage local governments to adopt the PPP model, the introduction of social capital is responsible for the construction, operation and management of urban infrastructure and other public goods. The role of the government is also changing, from investors to regulators. Using PPP model for urban infrastructure financing, construction, operation, it can not only alleviate the financial pressure of local governments, but also expand the investment area of social capital,can also improve the efficiency of public goods supply, ultimately achieve the maximization of social benefits of public goods. Not only to meet the urban development and social needs of the urban infrastructure, has it also provided a good investment direction for the idle funds in the market. But, because of PPP project has many participants, many kinds of risks. Therefore, compared with ordinary projects,the actual operation of the PPP project is more complex. So, how to identify the risk of the project and how to allocate the risk to each participant is the key to the success of PPP project. Under this background, this paper studies how to effectively and fairly share the risk of PPP project, and finally realize the smooth running of PPP project.Based on the PPP project risk in the field of urban infrastructure in China, this paper is based on the research results of PPP model and PPP project risk in recent years. Through a combination of theoretical and empirical methods,the present condition of the development of city infrastructure in the field of PPP mode and the city infrastructure construction,and PPP project risk analysis, risk sharing model of game theory to construct the PPP project in the field of infrastructure based on the city. Trying to solve how to reasonably share the PPP project risk problem, finally through the analysis of the success of PPP project implementation experience at home and abroad, for the further development of PPP mode in city infrastructure related suggestions.
