中文摘要：

通过理论分析将PPP项目中的信任划分为资格预审中形成的静态的初始信任和合同谈判与再谈判过程中动态演化的持续性信任，通过文献分析构建PPP项目中初始信任形成机理的概念模型，并运用结构方程模型的方法进行实证分析。研究结果表明：①管理能力、力量投入、社会声誉、财务状况、安全和环境能力、技术能力是PPP项目中初始信任的关键驱动因素；②过往表现和工程经验间接促成初始信任的形成；③初始信任的3个维度对其总体水平的贡献度相差不大。该研究成果可帮助公共部门优化PPP项目资格预审评审指标和评审标准，从而促使项目成功。

英文摘要：

Trust in PPP project is divided into the static initial trust formed in the prequalification and the dynamic continuous trust in the negotiation and renegotiation based on theoretical analysis. A conceptual model about the formation mechanism of initial trust in PPP project is first developed by a thorough literature review, and then tested by structural equation modeling. The main results are as follows： ① managerial competence, devotion, reputation, financial status, competence of security and sustainable development, technical competence are identified to be the key driving factors of initial trust in PPP projects ; ②performance in the past and experience affect the initial trust indirectly ; ③ there is no significant difference among the contribution degrees of initial trust＇ s three dimensions to its whole level. The research results can help the public sectors improve the review index and criteria of PPP project prequalification, and thus contribute to project success.
