Study On The Income Distribution Model Of Transport Infrastructure Construction Project Under PPP

With the deepening of marketization reform, the investment and financing modesof transport infrastructure construction project show the trend of multi-subjects andrisk and benefit sharing. As one of the marketization investment and financing modes,PPP（Public-Private-Partnerships）is applied widely and alleviates the problem that theinvestment and financing of transport infrastructure construction project mostlydepend on the government, because of its social financing characteristics. Aiming atsolving the problem of income distribution existing in the application practicegenerally, this paper try to make use of Shapley Value in Game Theory to establish theincome distribution mechanism of transport infrastructure construction project basedon PPP, so as to promote the cooperation of public-private alliance and perfect theoperation regulations of PPP, which is of great practical significance.Firstly, the theoretical basis and analysis method of transport infrastructureconstruction project, such as the economic attribute, classification, characteristics andthe investment and financing modes of transport infrastructure, are summarized; thedefinition, classification, connotation and application conditions of PPP are analyzed;the main contents of the income distribution of PPP are described in subjects ofincome distribution, basic principles, influencing factors and effectiveness evaluation4aspects; the principle and application conditions of Shapley Value and ANP aregiven.Then, the degree of project risks sharing of public-private cooperation alliance isdefined as the risk factor, which is quantified by analysis of transport infrastructureconstruction project risks elements with ANP, is brought into the Shapley Value;based on the principles of giving consideration to both fairness and efficiency, theShapley Value income distribution model with consideration of risk factors in PPP isproposed.Finally, the model is validated and analyzed through the Land Port Tconstruction project. Comparing different income distribution schemes of thegovernment and the private in each year, the result shows that, the model proposing inthis paper could promote the cooperation efficiency On the basis of the fairness and play a more important part in motivation comparing to income distribution modelsonly considering capital contribution.
