摘　　要：为了解决PPP项目的运营期漫长,在运营期内项目各种因素的影响将会导致价格与补贴的调整问题,设计了一种动态的调价与补贴模型来应对各种可能的项目状况,以期达到参与方的利益平衡.以政府、私营企业、公众三方满意度均衡为目标,通过PPP项目的关键影响因素建构了指标体系,以指标对三方的影响权重为系数,运用系统动力学理论,建立了PPP项目的动态调价与补贴模型,得到了基于三方满意的PPP项目关键目标体系及其内生反馈机制.在此基础上设计出了调价和补贴模型的实施步骤,实证研究表明该调价模型的计算简单实用,具有良好的调节作用,符合初始的构想,即三方满意、动态调价.There was a long-term operation period for PPP（public-private partnerships） projects.The changes of the projects inevitably resulted in the adjustments of prices and subsidies.The aim of this paper is to design a dynamic pricing and subsidy model to keep the interest balance in all changes of the project situation. Based on the balance of the tripartite（the public sector,the private sector and the general public） satisfaction mechanism,the objective system of PPP projects is structured by using the main objectives as indexes and the weights as modulus.Through system dynamics theory,the tripartite critical objectives system and the feedback mechanism of critical objectives are identified.Subsequently,the adjustment model is designed.A case study has been conducted to approve that the proposed method is practical and can be easily used.And the primary assumption that the balance of satisfaction of public sectors,private sectors and general public would be achieved by the proposed method is validated.
