Studies on Risk Management of the Urban Infrastructure Projects Based on the BOT Financing Model

With the acceleration of urbanized advancement in China, governments' high investment and low efficiency in urban infrastructure projects have already become a worldwide problem. The BOT financing model can be combined with government policy supports, investor's abundant fund and advanced management. The BOT financing model in urban infrastructure projects has greater risks, so their risk management is of great significance. The paper establishes risk evaluation index system of urban infrastructure projects on the BOT financing model, and sets up the risk evaluation model by use of Analytic Hierarchy Process (AHP) and Fuzzy Mathematics. We partially modify weight of AHP, by Fuzzy Cluster Analysis. Next, we establish the risk allocation model of urban infrastructure projects. Finally, we carry empirical analysis about the risk problem of an urban infrastructure project. Through comparing with result of model evaluation and measure of the risk allocation, empirical analysis indicates that the evaluation result of the model can reflect the risk situation of project thoroughly and objectively.
