Abstract: An enormous amount of research attention has been devoted to investigating migrant children’s depression, loneliness, discrimination, and risk behaviors from the perspective of typical deficit model of adolescence, while relatively little attention has been paid to positive developmental outcomes. Subjective well-being refers to cognitive and affective evaluations of our lives. It is a significant indicator of positive youth development(PYD). Previous research showed that the emotional problem was one of the most important factors that affected migrant children’s life quality. So the emotion regulation may be a linchpin for subjective well-being among migrant children. Furthermore, high self-esteem and resilience also are the key protective factors for children’s developments. Accordingly, from the perspective of PYD, the purpose of this study was to get better insights into the associations between emotion regulation strategies (i.e., reappraisal and suppression) and subjective well-being among migrant children and test the possible mediating roles of self-esteem and resilience. 639 migrant children aged 9–14 years old from three primary schools in Beijing were recruited for participation. They were asked to complete a battery of self-report questionnaires, including the Oxford Happiness Questionnaire (short form), Emotion Regulation Scale in Adolescents, the Rosenberg Self-Esteem Scale and the Resilience Scale for Chinese Adolescents. Firstly, descriptive statistics were utilized to describe the basic features of the variables. Then the multiple regression was conducted to acquire an understanding of the overall relationships depicted in the hypothesized model. The sequential mediation effects were estimated by the PROCESS macro for SPSS. Correlation analysis showed that reappraisal was positively associated with suppression, self-esteem, resilience and subjective well-being among migrant children. Suppression was negatively correlated with resilience, but had no relationships with self-esteem and subjective well-being. Self-esteem, resilience and subjective well-being were positively correlated with each other. Regression results indicated that cognitive reappraisal directly predicted migrant children’ subjective well-being, while suppression did not. Besides, cognitive reappraisal and suppression indirectly contributed to subjective well-being through both separate mediation path and chained mediation path of self-esteem and resilience. These findings demonstrated that it was meaningful to involve emotion regulation strategies, self-esteem and resilience when explaining migrant children’s subjective well-being. The important implication of this study is that cognitive reappraisal is an effective factor to promote the self-esteem, resilience and subjective well-being among migrant children by intervention. Meanwhile, we have a cautious attitude toward the value of suppression although some research showed that it had positive effects on interpersonal relationships in the collective culture，it might not be beneficial to migrant children under some circumstances. Thus, we should consider the specific events migrant children may encounter when we make an intervention plan. An additional implication is that we should also promote the subjective well-being of migrant children by developing their self-esteem and resilience, instead of just reducing or eliminating their problem behaviors.

摘要： 以639名流动儿童为被试，通过问卷调查探讨了认知重评和表达抑制两种情绪调节策略对流动儿童主观幸福感的影响及自尊和心理弹性的中介作用。结果表明：（1）认知重评既直接正向预测流动儿童的主观幸福感，又能通过自尊和心理弹性及自尊→心理弹性的序列中介作用间接预测流动儿童的主观幸福感。（2）表达抑制对流动儿童主观幸福感的直接预测不显著，但通过负向预测自尊和心理弹性及自尊→心理弹性的序列中介作用间接预测流动儿童的主观幸福感。
