合同柔性与项目管理绩效改善实证研究:信任的影响

An Empirical Study on Relationship between Contract Flexibility and Project Management Performance in Construction Project:The Perspective of Trust between Owner and Contractor

合同柔性对工程项目管理绩效改善的积极作用已得到理论研究支持,但缺乏基于样本数据的实证检验。从业主与承包商信任的视角,本文构建了合同柔性、项目管理绩效及信任驱动/调节理论模型,探讨了信任在合同柔性与项目管理绩效关系中的作用。通过对233份调查问卷的统计数据分析,工程项目合同柔性对项目管理绩效改善具有显著作用,而关系要素信任是合同柔性形成的驱动变量而非合同柔性与绩效改善间的调节变量,且信任对绩效改善具有正向影响,研究发现具有一定的理论意义及工程实践价值。

The empirical tests on relationship between contract flexibility and project management performance are still rare. Based on the perspective of trust,this study constructs a theoretical model about contract flexibility,project management performance and the trust between owner and contractor,and introduces trust as a driving variable or moderator variable. With an empirical study of 233 questionnaires,the results show that： contract flexibility has significant effect on project management performance,and the trust between owner and contractor is a driver variable rather than moderator,the trust has significant positive impact on project management performance.The findings are of great value both in theory and practice.
