Abstract:
A scientific and reasonable profit distribution mechanism is the key to the success of water diversion PPP project. Based on the basic principles of prof it distribution, we constructed an impact factor system of profit distribution with consideration to the features of water diversion PPP projects. Then, based on the Shapley value, we used the fuzzy synthetic method to determine the weight of each impact factor of profit distribution, and established an improved profit distribution model for water diversion PPP projects, so as to coordinate profit distribution and maximize profits for all stakeholders. Finally, we applied the model to an engineering case and verified the feasibility and validity of the model. The results showed that compared with the initial allocation scheme, the improved profit distribution mechanism not only can satisfy both individual rationality and group rationality, but also can measure the actual contribution of various stakeholders more truthfully. It does not affect the total profit of the water diversion PPP project, and only affects the distribution ratio between government, social capital, and franchise company of water diversion PPP project, whose profit distribution coefficients were 0.35, 0.41, and 0.24, respectively .
