利用中国教育追踪调查数据，以随迁子女和留守儿童为研究对象，构建倾向得分匹配模型和多重中介模型，分析随迁对农民工子女学业成绩的影响，并基于家校教育的视角，探究家校教育在“随迁-学业成绩”影响路径中的中介效应。研究发现，随迁对农民工子女学业成绩具有显著的正向影响，随迁能够显著提高农民工子女的总成绩和语文、数学、英语成绩。家校教育在“随迁-学业成绩”影响路径中具有一定的中介效应，家庭教育中的教育期望、教育投入、成员互动以及学校教育中的教学资源和关系氛围的中介效应显著。学校教育的累计中介效应高于家庭教育的累计中介效应，表明随迁对农民工子女学业成绩的改善更多的是通过学校教育这一影响路径来发挥作用。

Using the data from China Education Panel Survey and taking the children living with migrant parents and left-behind children as the research objects, the paper built propensity score matching model and multiple mediation model to analyze the influence of children’s migration with parents on their academic performance. Then based on the perspective of family-school education, this paper explored the mediating effect of family education and school education in the influence path of "migration-academic achievement". The result showed that migration had significant positive affect on the academic performance of migrant workers' children, migration improved the total grade，Chinese, math and English grades of migrant workers' children. Based on the mediating effect analysis, it is found that the education play a certain mediating effect in the influence path of “migration-academic achievement”, and family education expectation, family education investment, family member interaction, teaching resources and relational atmosphere from school education have a significant positive mediating effect. The cumulative mediating effect of school education is higher than that of family education, which shows that the improvement of the academic performance of children of migrant workers benefits more from the school education.
