Although long-term separation has made discrepancies between parents' educational aspirations and children's own educational expectations among families with left-behind children (LBC), limited researches on the influence of these discrepancies on children's mental health are carried out at present. Based on China Family Panel Studies (CFPS) conducted in 2018, we selected 875 LBC aged 9~15 as the sample, explored the influence of the direction and degree of these discrepancies on LBC's depressive symptoms by hierarchical regression, and examined the mediating role of children's academic self-efficacy and mediation effect pathway with Baron and Kenny method and Bootstrap mediation analysis methods. Results showed that LBC's mental health was worse when parents' educational aspirations were higher than their children's educational expectations, compared to that without discrepancies. The degree of such discrepancies was negatively associated with LBC's mental health. In the relationship between the direction of discrepancies and LBC's depressive symptoms, academic self-efficacy played a mediating role partially. In addition, the study indicated that mothers played a significant role in the development of LBC's mental health. These findings also provided critical evidence for the intervention practice of LBC's mental health.
