在政府和社会资本合作（PPP）模式中，社会资本方可能面临巨大风险。为了管理PPP项目风险，遵循ISO31000提出的“把风险管理融入组织的管理过程”原则，结合访谈调查成果，把PPP项目实施过程划分为6个阶段，分析社会资本方在每个阶段的风险管理目标，并确定每个阶段的风险管理重点，把风险管理过程融入PPP项目运作过程，从而形成了社会资本方的项目风险管理框架，并建立项目风险管理的6道防线，可为社会资本方管理PPP项目风险提供指导。
In Public-Private Partnership （PPP） projects， the private sector may face many risks. In order to manage PPP project risk， a PPP project risk management framework for the private sector was developed through combining the implementation process of PPP project with the risk management process according to the principle of ISO31000 that risk management shall be integrated into organizational management processes. In this framework， the PPP project lifecycle is divided into six stages by taking interview survey results into account. It analyzes the risk management objectives of the private sector in each stage and determines the focus of risk management in each stage， and establishes six defense lines for project risk management in private sector， thereby providing valuable reference for PPP project risk management.
