Abstract：Based on data from a survey of the migrant children in Wuhan in 2013, this paper utilizes exploratory factor analysis to explore the internal structure and influential factors of their social identification in order to objectively present their social identification, which provides the corresponding empirical study basis for migrant children's social identification. The results show that the social identification includes 3 factors,namely, region identification, culture identification and group identification. The overall level of their social identification has reached half levels, but internal differences still exist. The degree of these factors presents decreasing trend from region identification to group identification. The Social identification of migrant children is unbalanced between different dimensions. The degree of region identification of migrant children is higher, which explains the great appeal of city. With regard to group identification, some migrant children regard themselves as locals, some as outsiders, while some are very vague about their social identification. Migrant children have the strong consciousness of outsiders. They have strong ability of self-adjusting, and can quickly adjust their own group identification. Therefore, social identification is a product of social construction and self-construction. Household registration, different types of school, family income, family education content, parental perceived social distance, dwelling time and local social support have influence on their social identification. In short, the social identification system of migrant children will be a long process of transformation and change. The high level social identification depends on the joint efforts of migrant children, the native residents and the local government.
