摘要: 对于采用PPP模式的工程建设项目,当施工承包人两阶段参与,既是PPP的合伙人同时又承担工程施工承包任务时,存在增大自己施工收益损害其他PPP合伙人利益的道德风险。基于博弈论和委托代理理论,研究非对称信息条件下PPP项目管理机制设计问题。建立了业主、监理、承包商的质量控制决策模型,运用最优化原理,得到不同管理机制条件下各合伙人的最优收益分配比例、成本分摊比例以及业主、监理、承包商的最优质量控制水平,并通过算例计算分析,对常规 PPP模式和三种施工承包人两阶段参与的PPP建设项目管理机制进行了对比分析讨论。
Abstract: As the contractor is as one of PPP partners at the same time to undertake the project construction contract in the two stages of PPP construction projects, there is a moral risk of increasing their own construction gains while damaging other PPP partner's benefit. The design of PPP project management mechanism under asymmetric information is studied basing on game theory and principal-agent theory. The quality control decision model for owner, supervisor and contractor is established. Using the optimization principle, the optimal income distribution ratio, cost allocation ratio and the optimal quality control level of the partners are obtained in different management mechanism. And through Calculation and analysis by an example, PPP project management mechanism of conventional PPP mode and three PPP models of contractors participating in two-stage were compared and discussed.

公私合伙或合营(即PPP:Public-Private Partnership)是一种新型的公共基础合作建设思想。近年来越来越多的建设项目采用PPP形式,但由此在公私部门之间产生的收益分配、成本分担等问题却不容忽视(Alonso-Conde等,2007)[1],因此为PPP项目设计有效的机制,是PPP项目建设实践的重要内容。在大量PPP建设项目中,工程施工承包企业既是PPP的合伙人之一,同时又是工程的施工承包方,此时就会存在道德风险,即施工承包企业通过采取降低工程质量水平、加大承包核算成本(价格欺诈)等手段,提高自己的施工收益,损害其他合伙人的利益,所以需要研究此种情况下项目管理机制问题,以便规避道德风险和控制工程质量。
