PPP项目伙伴关系维系对项目价值影响的实证研究

在分析 PPP 伙伴关系维系基础上，立足伙伴关系思维，采用回归分析揭示关系维系对 PPP 项目价值的作用机理。结果表明，信任、承诺和合同对 PPP 伙伴关系行为具有显著的正向影响，其中合同和承诺对伙伴主体合作行为的效应较为显著。信任、承诺、依赖、合同和合作行为对 PPP 项目价值创造均存在显著的积极影响，其中信任对 PPP 项目价值提升的直接效应和总效应较大。依赖对 PPP 项目伙伴关系行为的影响不显著，政府能力、社会资本主体机会主义行为以及中国关系文化等因素是产生此结果的重要因素。在此基础上演绎管理启示，为 PPP 项目管理实践提供科学依据
