Study On The Risk Sharing Proportion And Income Distribution Of Water Treatment Works Project Under PPP

The wastewater treatment plant is the infrastructure project,and the PPP model is applied very early in our country.The PPP model will sewage treatment market,introduced a large number of social capital,one can reduce the pressure of the government lack of funds,two brought advanced technology and management experience,improve sewage disposal field service level and working efficiency of the enterprise.Sewage treatment plant,however,the PPP mode from project to project operation covers many links,many participants,and investment scale,yield is not high,recovery cycle is long,the interests of all parties Angle different,attitude to risk and risk to bear ability is uneven,the project risk allocation proportion is reasonable or not,has a great influence on the success of the PPP project.At the same time,the waste water treatment because of its quasi commonweal,need to refer to the local economic level,the residents' consumption ability etc.,so water price is not entirely to the market decision.In the face of social public good,the profit of sewage treatment enterprise is compromised in a certain degree,which will affect the initiative of social capital sewage disposal.How to scientifically analyze the PPP project both public and private risk proportion,design reasonable income distribution scheme,make the financing mode in the field of sewage industry government play its proper value,has become an important research direction in this field.This article first from the PPP project risk identification,assessment,share,and income distribution after reviewing the related literature consult,four aspects to summarize the characteristics of the water treatment works the PPP project risk,collect classified 34 risk factors,these factors will be divided into from three aspects of national level,market level and project level,made the risk index evaluation system.Secondly,by building the benefits and risk sharing proportion distribution model,the empirical analysis with specific cases,and using AHP-game theory model,calculate the risk of PPP project participants share proportion,the benefits of using Shapley value model,it is concluded that the various project participants assigned value,risks and benefits of reasonable assigned to each corresponding participation main body,to arouse the enthusiasm of all parties cooperate to complete the project smoothly,achieve a win-win effect is of great significance.
