Abstract: Conflicts between work and family has a significant inhibitory effect on employees' innovative behavior, and then directly reduces the core competitiveness of enterprises. This paper constructs a moderated mediation model according to the theory of resource conservation, and conducts a questionnaire survey among 1 199 employees, aiming at revealing the mechanism of the impact of work-family conflicts on employees' innovative behavior. The results show that work-family conflicts have significant negative impact on employees’ innovation behavior, and self-efficacy plays a completely mediating role in this process. Organizational identity negatively moderates the relationship between work-family conflict and self-efficacy, and at the same time negatively moderates the mediating role of self-efficacy between work-family conflict and employees' innovative behavior.
