全生命周期视角下综合管廊PPP项目风险识别与分配

Risk Identification and Allocation of Utility Tunnel PPP Project from the Perspective of Life Cycle

为了完善PPP项目风险研究,针对PPP项目与一般项目的区别,对PPP项目全生命周期进行了更全面、更准确的划分,并基于重新划分的全生命周期对综合管廊PPP项目的风险因素进行了识别,将全生命周期的风险因素归纳为阶段风险和贯穿风险。最后,综合考虑综合管廊项目的特点和风险分配的4项基本原则,分析了政府部门和社会资本各自承担的风险因素以及共担风险,并建立了完整的风险分配框架,以期为综合管廊PPP项目物有所值定量评价以及项目管理提供参考。

In order to improve the PPP project risk research,the whole life cycle of the PPP project is divided more comprehensively and more accurately in view of the difference between the PPP project and the general project,the risk factors of the PPP project in the comprehensive corridor are identified based on the full life cycle re-division,and the risk factors of the whole life cycle are summed up into the stage risk as well as penetration risk.Finally,considering the characteristics of the comprehensive utility tunnel and the 4 basic principles of risk allocation,this paper analyzes the risk factors and the shared risk undertaken by the government departments and social capital,and establishes a complete risk allocation framework,in order to provide reference for the quantitative evaluation and project management of utility tunnel PPP project.
