Feasibility Study On PPP Project Of Urban Underground Pipe Corridor

With the acceleration of urban modernization process,in order to improve people's living standards and urban infrastructure,underground pipe gallery is increasingly applied to urban infrastructure construction.However,because of the high cost of construction and the shortage of government finance,the underground pipe corridor is resisted.PPP mode(Public-Private-Partnership)brings social capital into the field of infrastructure investment,alleviating the shortage of government financial funds,make full use of the functions of government and social capital,and effectively distributing social resources,so as to improve construction efficiency and achieve win-win situation.However,the PPP model as one of the options to provide infrastructure products and services,the government can't prefer a purchase model or refute it.Thus,we should find a secientific quantitive foundation to judge it whether is a VFM choice.Therefore,in the early stage of the project operation,it is necessary to use scientific methods to discuss the economic feasibility of the PPP model.Based on the description of the VFM evaluation system the evaluation system,which is issued by the Ministry of finance.We should carry out the decisionmaking process in advance.Then,I will demonstrate the example quantitative analysis,which can be for government.First,I will briefly introduce the related theoretical research on the construction of urban underground pipe gallery.I will emphasize the concept and connotation of PPP mode and the VFM evaluation system and summarize the development status of PPP project in recent years.Secondly,based on the specific object of the underground pipe Corridor project,I establish the VFM evaluation model of the underground comprehensive pipe Corridor project under the PPP model.The core elements of VFM evaluation model are analyzed in detail,and compare the calculation method of components and connotations.Then,I select the suitable calculation method for underground pipe corridors in China and bulid a complete VFM quantitative evaluation model.Finally,using the VFM evaluation of the PPP projoct model in Nanning city underground pipe gallery,I can verify the applicability and feasibility of VFM quantitative evaluation model.Thus,this can provides a scientific basis of measurable PPP model for the underground pipe gallery project for government.
