Existing literature on construction innovation has not achieved an in-depth understanding of how and under which conditions individuals engage in creative activities to facilitate project task performance. In this study, 286 matched data sets between project members and leaders/supervisors, were collected and examined using a mediated moderation model. Drawing from the conservation of resources theory, individuals’ innovative behaviors and leaders’ empowerment strategies were found to positively affect project performance. Leader-member exchange (LMX) both moderates and augments the relationship between innovative behavior and project performance. Further, LMX mediates the moderation effect of empowering leadership and enhances the innovation process. The results of this study offer guidance on how project practitioners can facilitate project performance by motivating innovation in construction projects through empowering strategies and relationship development. This research extends and enriches the current understanding of the processes linking innovative behavior and project performance by identifying the mediating moderation mechanism of empowering leadership and LMX.

关于建筑创新的现有文献尚未深入了解个人如何以及在何种条件下从事创造性活动以促进项目任务绩效。在这项研究中，使用中介调节模型收集和检查了项目成员和领导/主管之间的 286 个匹配数据集。根据资源保护理论，发现个人的创新行为和领导者的授权策略对项目绩效有积极影响。领导成员交换 (LMX) 既调节又增强了创新行为与项目绩效之间的关系。此外，LMX 调解了授权领导力的调节作用并增强了创新过程。本研究的结果为项目从业者如何通过授权策略和关系发展激励建设项目创新来促进项目绩效提供了指导。本研究通过确定授权领导和 LMX 的中介调节机制，扩展并丰富了当前对创新行为与项目绩效联系过程的理解。
