项目中60%左右的问题是界面管理不到位或有欠缺引起的。在中国情境下，为更好地提出解决组织界面管理问题的有效方案，运用计划行为理论，以低信任度建设市场环境为背景、组织界面管理行为背后主观心理因素为视角，运用结构方程模型构建多因子中介模型，基于295名设计-采购-施工总承包（EPC）领域相关人员调查数据，验证信任和组织界面管理行为之间的作用机理以及心理影响机制。结果显示：信任对组织界面管理行为意愿的影响主要通过态度、主观规范、知觉行为控制这3个中介变量传递；在3条中介路径中，态度的中介效应最强，而知觉行为控制的中介效应最弱。可知内部心理因素是形成组织界面管理行为意愿的重要前提，而EPC项目管理人员对组织界面管理行为的积极态度未全部转化为知觉行为控制，部分管理人员由于感知资源掌控能力弱而放弃实施组织界面管理。由此分别从业主和总承包商两方面提出中国情境下EPC项目组织界面管理的对策。

About 60% of the problems in the project are caused by poor interface management. In the Chinese context, to bring forward a better way to solve the interface management problem, this study used the theory of planned behavior, took the low-trust construction market environment as the background and the subjective psychological factors of organizational interface management behavior as the perspective, and used structural equation model to construct a multi-factor mediation model. Then this study verified the relationship between trust and organization interface management behavior and its psychological impact mechanism based on the survey data of 295 personnel in Engineering-Procurement-Construction(EPC) projects. The results show that the influence of trust on the organization interface management behavior intention is mainly transmitted through three mediating variables: attitude, subjective norm, and perceived behavior control. Among the three mediation paths, the mediation effect of attitude is the strongest, while the mediation effect of perceived behavior control is the weakest. It indicates that internal psychological factors are an essential prerequisite for the formation for the formation of organization interface management behavior intention. However, the positive attitude of EPC projects managers towards organization interface management behavior in China is not fully translated into perceived behavior control, and that some managers have given up implementing organization interface management due to their weak ability to control resources. Therefore, the countermeasures for the organization interface management of EPC projects in Chinese context were proposed from the two aspects of the owner and the general contractor respectively.
