This study aims to explore the influence of role stress (role ambiguity and role conflict) on job burnout and job performance in construction project managers in the Chinese construction industry. Based on the JD-R (Job Demands Resources) model, this study introduces career calling as the moderating variable, in order to develop a theoretical model. The theoretical model is then tested with structural equation modeling. This work uses data from 191 owners, contractors, subcontractors, and supervisors in the Chinese construction industry. The results indicate that: (i) role ambiguity has a negative and significant effect on job burnout and job performance; (ii) role conflict has a negative effect on job burnout, but has a non-significant influence on job performance; (iii) job burnout has a negative impact on job performance; (iv) career calling negatively moderates the relationship between role ambiguity and job burnout, and positively moderates the relationship between role conflict and job performance. Furthermore, the results also show that career calling can positively moderate the effect of role conflict on job burnout. This study expands the existing body of knowledge by reasonably controlling role stress and appropriately introducing career calling. In addition, the study provides some suggestions relevant to construction project management.
本研究旨在探讨角色压力（角色模糊和角色冲突）对中国建筑行业工程项目经理的工作倦怠和工作绩效的影响。基于工作要求-资源（JD-R）模型，本研究引入职业召唤作为调节变量，以构建理论模型。然后，使用结构方程模型对理论模型进行测试。本研究使用了来自中国建筑行业的 191 位业主、承包商、分包商和主管的数据。结果表明：（i）角色模糊对工作倦怠和工作绩效有负向显著影响；（ii）角色冲突对工作倦怠有负向影响，但对工作绩效没有显著影响；（iii）工作倦怠对工作绩效有负向影响；（iv）职业召唤负向调节角色模糊与工作倦怠之间的关系，正向调节角色冲突与工作绩效之间的关系。此外，研究结果还表明，职业召唤可以正向调节角色冲突对工作倦怠的影响。本研究通过合理控制角色压力和适当引入职业召唤，扩展了现有知识体系。此外，本研究还为建筑项目管理提供了一些相关建议。
