BT工程项目风险分析与效益共享研究

针对BT工程项目风险分配原则问题,首先分析了BT工程项目所面临的两类风险:普通建设模式下的风险与BT模式特有的风险.其次,根据"风险分担,效益共享"的原则,建立了风险分担的数学模型.模型结果表明,项目风险由对该风险偏好系数最大的一方去承担,项目的整体效益最大.最后,根据该结论对BT工程项目提出了具体的的风险与效益分配原则,对指导项目各参与方进行BT项目谈判与建设实施具有实际指导作用.

Study on the Risk Analysis and Benefit Sharing in BT Construction Project

As a newly emerging financing method,BT(Build-Transfer) Mode has demonstrated its extensive application in infrastructure construction.In allusion to the principle of BT project risk allocation,this paper first provided an analysis on two kinds of risks within BT Mode: the risk as common construction mode does and certain particular risks of its own.And then,based on the principle of "risk sharing and benefit sharing",it established the mathematical model of risk sharing.The model result shows that the project’s maximum overall efficiency will be achieved when the participant who has the largest risk preference coefficient bears the project risk.Finally,according to the conclusion,it puts forward specific principles of the apportionment of risks and benefits,which can serve as practical guidelines for each participant during BT project negotiation.
