“…A family's economic condition determines how much parents can invest in their children's education and development (Becker, 1991;Blau, 1999;Brooks-Gunn and Duncan, 1997;Coleman, 1988;Dahl and Lochner, 2012;Duncan et al, 1994;Duncan et al, 1998;Kaushal et al, 2011). Families with higher levels of income can provide material advantages, such as more learning opportunities and resources, that is, high-quality private tutoring (Zhang and Xie, 2015). Another perspective emphasizes families' non-monetary resources, such as parenting attitudes and practices, and family environments (Alexander et al, 1994;Baharudin and Luster, 1998;Cheadle and Amato, 2011;Chen et al, 2000;Davidov and Grusec, 2006;Davis-Kean, 2005;Garrett et al, 1994;Heckman, 2006;Lareau, 2011;Mayer, 1997).…”
