污水处理PPP项目中市场需求变化风险共担的实现

The Realization of Risk Sharing of Market Demand Changes in PPP Projects for Sewage Treatment

通过文献分析识别出污水处理PPP项目中市场需求变化风险的共担是通过最低需求保证实现的,且包括总成本和二部制两种收费价格结构。筛选3个代表性案例项目,对比分析其实际处理水量小于等于基础水量、介于基础水量与设计水量之间、大于设计水量时的服务费结算单价构成,并讨论各案例做法的相对合理性。在此基础上,为PPP实践部门提出3点管理启示:①公私双方应在PPP合同中明确、具体地约定共担风险的实现方式;②公私双方风险共担的实现应遵循公平原则,追求风险与收益对等;③公私双方在谈判协商时应考虑社会公众的利益,以实现多方共赢。

Through literature analysis,this paper identifies that the risk sharing of market demand changes in PPP projects for sewage treatment is realized through the minimum demand guarantee,and includes the total cost and the two-part charging structure.Then,selects three representative case projects,and makes a comparative analysis of their service fee settlement prices when the actual treated water volume is lower than or equal to the base water volume,between the base water volume and the designed water volume,and higher than the designed water volume,and discusses the relative rationality of each case.On the basis,gives three management suggestions for the PPP practice departments:①the public and the private should clearly and concretely agree on how to share risks in the PPP contract;②the realization of risk sharing between the public and the private should follow the principle of fairness and pursue the equalization of risks and benefits;③the public and the private should consider the interests of social public in the negotiation and consultation so as to achieve a win-win situation for all parties.
