Abstract: Creative work input is regarded as a key driving force underlying the survival and development of organizations, so how to stimulate employees’ creative work involvement has become a burning question in the field of organization. Based on the role expectation theory, this paper constructs a mediated effect model to test the mechanism and boundary conditions of the influence of a supervisor’s coaching behavior on his/her supervisees’ creative work involvement from the perspective of the expectation of leadership innovation. The results show that: (1) supervisor’s coaching behavior has a positive effect on supervisees’ creative work involvement; (2) the perception of meaningful work plays a fully mediating role in the relationship between supervisor’s coaching behavior and creative work involvement; (3) leader creativity expectation plays a moderating role in the influence of meaningful work perception on creative work involvement; (4) leader creativity expectation regulates the relationship between supervisor’s coaching behavior and creative work involvement through the perception of meaningful work. The conclusion of this study not only deepens the research on the mediating mechanism of the effectiveness of supervisor’s coaching behavior on employees’ creative work investment, but also enriches the scope of effectiveness of leadership innovation expectations, and provides new ideas and interpretations for employees to actively participate in creative work.

Key words: supervisor’s coaching behavior, perception of meaningful work, leader creativity expectation, creative work involvement
