Research On Profit Distribution Of PPP Infrastructure Projects Based On Shapley Value Of Multiple Factor Correction

Now,a demand gap appeared and continues to expand between the constrained supply capacity and infrastructure as the representative of the growing public goods,this new features will profoundly change our infrastructure supply mode.In this context,entirely by the government-led infrastructure investment model need to reform.PPP(Public-PrivatePartnership)model has become an important direction of China's infrastructure construction investment and financing reform.At the same time,there are also many problems and obstacles in the development of PPP,which restricts the pattern wider applications,such as return on investment mechanism and revenue model is not perfect,of which the distribution of benefits is one of the key issues need to study.PPP profit distribution means public and private sectors to determine the scientific and reasonable distribution of benefits scheme,PPP infrastructure projects can be realized on the basis of cooperation.Scientific and rational distribution of PPP infrastructure projects both public and private benefits programs that can effectively promote the public sector,the private sector is actively involved in the project construction and operation,to achieve the maximum benefit of the project and ensure the success of the project.In this paper,elaborated the theory of PPP infrastructure project stakeholders who compared the current method of distribution of benefits of PPP infrastructure projects and features by analyzing the distribution of benefits abroad PPP infrastructure project results.At the same time,established distribution model PPP infrastructure project is based on the interests of Shapley value by parsing the PPP infrastructure project the interests of stakeholders and partner base.At the foot of the models and improved that affect the interests of PPP infrastructure projects mainly three factors allocation,that is,both public and private investment in the proportion of resources,as well as the size of the risk borne by the complexity of the importance of the size of the task undertaken.Based on this model,using T-AHP method and fuzzy mathematics price on AHP analysis and evaluation of factors,established a PPP infrastructure project benefits Shapley value allocation model based on multi-factor correction.Through examples and application analysis,studies show that the use of the PPP model correction interests allocation problem is feasible.It can provide some reference for the future distribution.
