Value for money(VFM) assessment has been officially proposed to provide a reference for selection of projects planning to adopt PPP. Based on the bottlenecks of VFM application in China and the uncertainties for urban infrastructure PPP projects, a discounted cash flow(DCF) model is established for VFM of infrastructure PPP projects. Then, a Monte Carlo simulation model is established on the basis of uncertainty factors for VFM. Through the analysis of Huai'an trams PPP project, coping strategies of uncertainties for VFM are put forward. Findings of the research may propel the establishment of a complete VFM evaluation system for PPP projects. Key instructional functions of VFM during the process of decision-making can be brought into full play and PPP may develop orderly.展开更多
物有所值(Value for Money,VFM)评价,可为PPP项目前期立项决策提供有力支持。首先分析各国VFM定性评价相关政策,对比英国、美国、加拿大、澳大利亚的VFM定性评价,然后总结我国VFM定性评价现状及问题,最后阐述各国VFM定性评价对我国的启...物有所值(Value for Money,VFM)评价,可为PPP项目前期立项决策提供有力支持。首先分析各国VFM定性评价相关政策,对比英国、美国、加拿大、澳大利亚的VFM定性评价,然后总结我国VFM定性评价现状及问题,最后阐述各国VFM定性评价对我国的启示,为我国完善VFM定性评价提供参考。展开更多
