Rural sewage treatment is in need of more capital investment, in which the financing model of PPP (public-private partnership) is able to encourage the investment of social capital in this sector. Risk sharing is one of the core features in the PPP model. In view that the risk loss of projects cannot be accurately estimated, this article describes the uncertainty of risk loss with fuzzy numbers and allocates the distribution of risk loss among the participants of rural sewage treatment PPP projects with interval fuzzy Shapley value to ensure a more reasonable and effective risk distribution.
