The Price Adjustment Mechanism of PPP Project-Based on The Objective Management Theory

Aiming to balance the interests of the public sector, the private sector and the general public, a price adjustment model is established based on the theory of objective management. A structured questionnaire survey was conducted by focusing on the identified critical objectives, and the weights of the critical objectives influencing the satisfaction of the tripartite were figured out. The quantitative evaluation of the critical objectives was done through expert score method, according to which the tripartite evaluation system of critical objectives was set up. Furthermore, the relationship amongst the critical objectives was identified by using the method of system dynamics, within which the feedback mechanism of the critical objectives was examined. A price adjustment mechanism for PPP projects by the combination of the tripartite evaluation system and the feedback mechanism of critical objectives were finally established.
