Abstract: To explore ways of creating a maternity-friendly environment from the perspective of enterprises, 103 leader-employee paired data is used to analyze the relationship between family motivation and workplace behavior of employees with “only child”. Results show that family motivation positively affects employees’ proactive behavior and negatively affects their withdrawal behavior. Employees’ occupational role commitment not only moderates the relationship between child’s age and employees’ family motivation, but also moderates the indirect impact of child’s age on employees’ proactive behavior and withdrawal behavior through family motivation, and the mediating effect of employees’ family motivation is significant when occupational role commitment is low. This study not only expands the research on the reasons of family motivation and on family-work promotion, but also proves that child and career can be balanced, which has important implications for creating a maternity-friendly business environment.

Key words:  maternity-friendly enterprises, negative population growth, family motivation, occupational role commitment, workplace behavior
