基于家庭环境和同伴效应的维度，并采用城镇初中生作为参照组，利用中国教育追踪调查（CEPS）2014—2015学年数据，探讨了农村流动初中生不良行为的影响因素及其地区差异，结果表明：家庭环境是抵御不良行为的重要保护因素，优质同伴的榜样示范作用一定程度上能够抑制不良行为，而结交不良同伴则会对个人不良行为起到推波助澜的作用；相对城镇初中生而言，农村流动初中生的上述影响效应更加显著；无论是东部还是中西部地区，家庭和同伴因素对农村流动初中生不良行为的影响均大于城镇初中生，在中西部地区这两类群体之间的影响差异更大。

Based on the dimensions of family environment and peer effects, and taking urban junior middle school students as reference group, using the data of China Education Tracking Survey (Academic Year 2014-2015), the paper explores the influencing factors of rural migrant junior middle school students' misconducts and the regional differences. The results show that family environment is a vital protective factor against the misconduct while the role model of high-quality companions can somewhat restrain the students’ bad behaviors. However, making friends with bad companions will deteriorate the individual misconduct. Compared with the urban junior middle school students, the above effects of rural migrant junior middle school students are more significant. Whether in the eastern region or in the central and western regions, the influence of family and peers on the rural migrant junior middle school students’ misconduct is stronger than that of urban junior middle school students, with remarkable differences between these two groups in the central and western regions.
