摘　　要：采用问卷调查法,对某中学863名学生的同伴社交网络进行分析,探究正向匹配效应在青少年同伴社交网络建构过程中的作用。采用指数族随机图模型分析发现:(1)基于流动身份的正向匹配效应会对青少年同伴社交网络的建构产生显著影响,并造成流动青少年与本地青少年的社交隔离;(2)因青少年身份的不同,正向匹配效应对其同伴社交网络建构的影响各异,对流动青少年之间的同伴社交网络建构无显著影响,但对本地青少年之间的同伴社交网络建构有显著影响;(3)基于流动身份的正向匹配效应会逐渐被年级和班级中的聚焦效应所调节,仅对低年级青少年的同伴社交网络建构有显著作用。建议从初一年级流动青少年入手,消除社交歧视,提高班级学生互动频率,增加本地青少年与流动青少年的互动机会,以促进流动青少年融入学校生活。Using the questionnaire survey,there are 863 middle school students who had been surveyed in a migrant children middle school in the southwest of China to collect the information referring to their peer social networks,to explore the effect of assortative mixing on the peer social networks between migrant and local juveniles.Based on the exponential-family random graph model(ERGM),it was found that:(1)the assortative mixing arisen by the migrant identity is a significant predictor for the foundation of peer social networks among juveniles;(2)the assortative mixing works differently when affecting the foundation of peer social networks among the migrant and local juveniles,as it plays as a non-significant predictor for migrant juveniles’peer social networks,but significant for local youngsters;(3)the grade and foci effect may moderate the effect of assortative mixing on the peer social networks,as the effect of assortative mixing on the peer social networks would become non-significant when the juveniles enter into higher grade and their foci effect increase.Therefore,starting from the freshmen by eliminating social discrimination,strengthening social interactions within the same class,and increasing the social activities between local and migrant juveniles are suggested.
