信任视角下PPP项目风险合作治理研究

Research on Risk Cooperative Governance of PPP Projects Based on Trust

信任是PPP项目管理的关键要素之一。通过调节信任供给对PPP项目进行风险合作治理,是维持项目的稳定性和提高项目绩效的重要途径。本文以合作治理理论为导向,针对PPP项目建设过程中隐性违约风险,从信任视角出发,基于“初始信任—专用资产投入—持续信任”的交互关系,构建政府和社会资本方决策演化模型,分析其信任行为演化路径和规律,探究隐性违约风险合作治理机制。研究结果表明:不同的初始信任下,政府和社会资本方会做出不同的行为决策。违约成本系数越高,越有利于政府和社会资本互信合作;沉没系数越高,越有利于抑制社会资本的隐性违约行为。基于此,应加强资格预审、建立健全声誉机制、根据不同项目特征设置最低初始信任标准,这有助于缓解政府财政压力,提高政府治理能力。

Trust is one of the key elements of PPP projects’management.It is an important way to maintain the stability and improve the performance of PPP projects to conduct risk cooperation governance by adjusting trust supply.Under the guidance of cooperative governance theory,a decision-making evolutionary model of the government and social capital based on the"initial trust-dedicated assets investment-continued trust"interactive relationship is built to analyze the evolutionary path and rules of their behaviors to deal with implicit default risks of PPP projects.The results show that,firstly,the initial trust can affect the behaviors of the government and social capital.Secondly,the higher the cost coefficient of default is,the more willing they want to cooperate.Thirdly,the higher the sinking coefficient is,the more conducive for public sectors to cope with the implicit default risk.Finally,strengthening prequalification,establishing and improving reputation mechanism,and setting minimum initial trust standards according to the characteristics of different projects are the inspirations of our research,which injects fresh ideas into risk governance of PPP projects,helps relieve government financial pressure and improve government governance ability.
