The academic performance of migrant children in China has been a subject of growing concern. With a significant number of parents migrating for work, these children often face unique challenges in their educational journey. While some studies have shown a positive impact of parental income on academic outcomes, it remains uncertain whether this effect outweighs the consequences of reduced parental time and neglect of educational investment. This research aims to investigate the various factors contributing to the divergent academic performances of migrant children in the context of parental migration. This article reviews the literature on parental migration and highlights the complex interplay of factors shaping the academic trajectories of migrant children. While parental income can positively influence academic performance, its efficacy is contingent on mitigating the effects of reduced parental time and educational neglect on children’s cognitive and non-cognitive development. Furthermore, the external environment significantly impacts the mental health of these children, necessitating enhanced support systems for their psychological needs. In conclusion, this study's findings emphasize the significance of creating focused interventions and assistance programs to meet the particular difficulties experienced by migrating children in China.
