基于效用理论的污水处理PPP项目风险分担研究

污水处理PPP项 目具有投资金额大、项 目主体关系复杂等特征,使得其存在众多复杂的风险因素.而且,PPP模式在污水处理领域实际应用过程中,存在政府和社会资本方风险分担不合理、双方权责划分不清的问题,导致项 目建设、经营效率低下.为实现项目成本最小化、效益最大化,进一步明确污水处理PPP项 目 公私双方的共担风险分担比例是必要的.文章以政府部门和社会资本方为风险分担主体,基于效用理论构建公私双方效用 目标函数,建立风险最优分担模型并对其求解.结果表明:最小风险成本取决于公私双方的共同期望成本,公私双方在项 目中的谈判地位直接影响风险分担比例的合理性.最后,通过案例应用,验证了此风险分担模型的可行性.
Research on risk identification and sharing in sewage treatment PPP projects based on utility theory
Wastewater treatment PPP projects are characterized by large investment amounts and complex project subject re-lationships,which makes them subject to numerous complex risk factors.Moreover,in the actual application of the PPP model in the field of sewage treatment,there are problems of unreasonable risk sharing between the government and the so-cial capital side,and unclear division of rights and responsibilities between the two sides,which leads to inefficiency in the construction and operation of sewage treatment PPP projects.In order to minimize project costs,maximize benefits,it is necessary to further clarify the risk sharing ratio between the public and private sides of sewage treatment PPP projects.Based on the analysis of the risk characteristics and risk sharing principles of sewage treatment PPP projects,the govern-ment departments and social capital parties were takon as the main risk sharing bodies,the public and private utility objec-tive functions were constructed based on the utility theory,and the optimal risk sharing model was established.The results show that the minimum risk cost depends on the common expected cost of government departments and social capital,and the negotiation position of public and private parties in the project directly affects the reasonableness of the risk sharing rati-o.Finally,the feasibility of this risk sharing model is verified through case studies.
