Assimilation theories argue that social ties with majority-group members enhance the structural integration of ethnic minority members, whereas under certain conditions, coethnic social ties can also benefit minority members' socioeconomic outcomes. We examine these propositions through a social network perspective, focusing on friendship networks and educational expectations in adolescence, during which peer socialization is crucial. Longitudinal data from 1,992 adolescents in 91 classrooms allow us to investigate co- and interethnic social selection and social influence processes as well as their aggregated outcomes. In terms of friendship selection, we find that Turkishorigin minority adolescents in Germany have distinct preferences for friends with high educational expectations, among both co- and interethnic peers. In contrast, social influence on Turkish-minority adolescents' educational expectations is not uniform: only majority-group friends exert a significant (positive) influence. Our results emphasize that bridging social capital gained from social ties with majority-group members enhances ethnic minority adolescents' educational integration.

社会和结构整合之间的联系：青少年社交网络中的同族和族际友谊选择和社会影响

同化理论认为，与多数族群成员的社会联系增强了少数族裔成员的结构整合，而在某些条件下，同族社会联系也有利于少数族裔成员的社会经济成果。我们通过社交网络的角度来研究这些命题，重点关注青春期的友谊网络和教育期望，在此期间同伴社交至关重要。来自 91 个教室的 1,992 名青少年的纵向数据使我们能够调查共同和跨种族的社会选择和社会影响过程以及它们的汇总结果。在友谊选择方面，我们发现德国的土耳其裔少数民族青少年对具有高教育期望的朋友有明显的偏好，无论是同族还是异族。相比之下，社会对土耳其少数民族青少年教育期望的影响并不统一：只有多数群体的朋友才会产生显着（积极）的影响。我们的结果强调，从与多数群体成员的社会联系中获得的桥梁社会资本增强了少数民族青少年的教育融合。
