Efficiency Assessment on the Incremental and Stock PPP Projects—Based on AHP-Fuzzy Comprehensive Method under "Multiple Participation"

Abstract

Abstract. The development of the incremental PPP projects and the stock PPP projects are uneven and there are very few successful cases of the stock PPP projects. To explore the reason, we built the evaluation indicator system according the different demands of different participants of PPP firstly, then adjusted the indicators system according to the characteristics of the increment and stock projects. That is an indicators system based on multiple participation. Lastly, used the AHP-fuzzy comprehensive evaluation method to evaluate the chosen cases and found the efficiency of the stock PPP project lower than the incremental one. The reason is that the lack of support policy and the incomplete of laws cause the risk and the management of stock project higher.
