Research On Risk Sharing Of Urban Underground Integrated Corridor Project Under PPP Mode

Urban underground integrated pipe gallery is based on the rapid development of urbanization in our country and the relative backwardness of infrastructure construction in the country.It is introduced by the government.At present,there is still a gap between the construction of underground integrated pipe network in China and foreign countries.However,the development in recent years has been very rapid.City underground integrated corridor not only can solve the increasingly serious "road zipper" problem,but also to co-ordinate various types of municipal pipelines,is conducive to planning,construction and management.But also to solve the overhead line network intensive,frequent accidents such as pipeline,is conducive to the protection of urban security,beautify the city landscape,enhance the city intensive development.The use of PPP mode to build and operate underground integrated corridors is considered an innovative mechanism for project investment.The PPP model can stimulate the social capital to generate interest in the construction of the urban integrated corridor,alleviate the huge financial pressure on the construction of the urban underground integrated corridor and enhance the service quality of the infrastructure or public goods.At the same time,the social capital actively participates in the urban underground integrated corridor Construction and can get a certain income,for both sides is a win-win cooperation.This paper mainly elaborates the concept of PPP mode,urban underground corridor and risk,analyzes the current situation of PPP mode and urban underground corridor,and summarizes some problems encountered in the development process.Finally,the AHP method and the close value method are used to analyze the cases,and the natural risk is taken as an example.It is concluded that in this kind of risk,the participants in the participant Of social investors should bear the main risk of the conclusion.And put forward some suggestions on how to solve the problem of risk sharing.The research of this paper not only enriches the theoretical research of the urban underground integrated corridor under the PPP model,but also adds a new research idea for the quantitative research of risk sharing,and also provides a certain consideration for the successful construction of the urban underground integrated corridor project under the large-scale PPP model The reference.
