中文摘要：

在文献综述的基础上,将信任划分为计算型信任和关系型信任,构建了包括信任的前因、信任（计算型信任和关系型信任）、项目成功的整体理论模型.对承包商进行调研,根据实证数据,对理论模型加以验证和完善.结果表明：信任的前因包括业主方特征（声誉、能力、言行一致性）和双方关系特征（双方的沟通、相互性、合同）;计算型信任对关系型信任具有线性作用;两类信任对项目成功具有重要作用,但关系型信任的作用更大.

英文摘要：

On the foundation of literature review,trust has been classified into calculative trust and relational trust.A whole theoretical model including antecedents of trust,trust and project success has been set up.Investigation was carried out in the contractor.According to empirical data＇s fitting result in structural equation model,the theoretical model has been amended,and a best fit theoretical model has been formed.There are conclusions as follows： antecedents of trust conclude the characteristics of the trustee（reputation,competency and promise-keeping） and the relationship between the trustor and the trustee（communication,reciprocity and contract）.Calculative trust has linear function on relational trust and both calculative trust and relational trust have vital function on project success,but relational trust＇s function coefficient is stronger.
