Employees’ creative idea enactment is critical for organizational creativity assessment and innovation implementation. In the paper, we want to develop and verify a moderated chain mediation model to explore the impact of supervisor developmental feedback on the enactment of employees’ creative ideas, and to investigate the moderating role of psychological empowerment further. Hierarchical regression analyses of the multi-time data from 375 employees in China indicate that positive emotions and work engagement, respectively mediate the relationship between supervisor developmental feedback and employees’ creative idea enactment. Simultaneously, positive emotions and work engagement form chain mediation between supervisor developmental feedback and creative idea enactment. Besides, we find that psychological empowerment negatively moderates the relationship between supervisor developmental feedback and employees’ positive emotions, as well as moderates the chain mediating effect of this paper. The present study not only contributes to the literature on feedback and innovation, but also provides practical guidance on how to seek remedies to facilitate employees’ creative idea enactment from the perspective of human resource management.
