社会网络与教育代际流动——基于CFPS的实证分析

How Do Social Networks Affect the Education’s Intergenerational Mobility——Empirical Analysis Based on CFPS

保障教育机会公平是提高社会流动性,实现共同富裕的重要途径。本文基于中国家庭追踪调查(CFPS)2020年数据,从社会网络规模和强度两个维度综合测度社会网络,研究社会网络对教育代际流动的影响。结果表明,社会网络显著促进了教育代际流动,且该促进作用在中西部地区、农村地区、高人力资本家庭及女性子代群体中更为明显。进一步分析表明,降低父亲学历较低家庭受信贷约束的概率,以及提高此类家庭的金融市场参与是社会网络改善教育代际流动性水平的重要机制。因此,建议进一步发挥非正式制度在改善代际流动性方面的作用,营造更加平等的教育环境来促进社会公平正义。

Ensuring fair educational opportunities is an important way to improve social mobility and achieve common prosperity.Based on the data of Chinese Family Panel Studies(CFPS)in 2020,this paper comprehensively measures the social network from the size and intensity of social networks and studies the effect of social networks on the intergenerational educational mobility.The results suggest that social networks significantly improve intergenerational educational mobility.And this effect is more obvious in the central and western regions of China,rural areas,high human capital families and the female offspring groups.Further analysis shows that social networks can improve intergenerational educational mobility by alleviating the credit constraints of families whose father has a lower educational background and improving the financial market participation of such families.Therefore,this paper suggests that the role of the informal system in improving intergenerational mobility should be further played,and we should achieve social equity and justice by creating a more equal educational environment.
