Purpose: Leaders try to stimulate follower taking charge to promote organizational change and effectiveness in current increasingly complex and changing environment. Based on social identity theory, we developed a mediated moderation model in which affective commitment was theorized as a mediating mechanism underlining why followers feel motivated to taking charge with the supervision of inclusive leadership. Furthermore, traditionality should be a relevant boundary condition to moderate such a relationship in China. Methods: There was three times lagged research conducted at the city of Shanghai, Shenzhen, and Nanjing. A series of valid questionnaires were accomplished by 246 participants, including the inclusive leadership, affective commitment, traditionality, and follower taking charge. Our model adopted hierarchical regression analysis to explore hypothesis. Results: Inclusive leadership is positively related to affective commitment (β= 0.589, p < 0.001). Affective commitment was positively related to follower taking charge (β= 0.165, p < 0.01). Affective commitment mediates the relationship between inclusive leadership and taking charge with 95% bias-corrected confidence intervals [0.068, 0.233]. Interactive effect of affective commitment and traditionality on follower taking charge was also significant (β=-0.189, p <0.001), and the effect of affective commitment on follower taking charge was more pronounced and positive with low (b = 0.361, p <0.001) rather than high (b =0.172, ns.) level of affective commitment. Moreover, the indirect effect of inclusive leadership on taking charge through affective commitment was significant when traditionality was low (b = 0.270, 95% CI = [0.179, 0.371]), the indirect effect became insignificant with high traditionality (b = 0.046, 95% CI = [-0.034, 0.123]). Conclusion: Our study shows that affective commitment mediates the relationship between inclusive leadership and follower taking charge. Moreover, the influence of affective commitment on follower taking charge was moderated by traditionality. Affective commitment was positively associated with taking charge only for followers with low traditionality. Additionally, the mediated moderation relationship between inclusive leadership and follower taking charge via affective commitment was stronger under low traditionality.
