中文摘要：

采用整群取样法对北京市的1164名流动儿童进行问卷调查，从城市认同与老家认同两方面考察流动儿童社会认同的特点、影响因素、与城市适应的关系，及其在教育安置方式与城市适应关系中的中介作用。结果表明：（1）流动儿童的社会认同大多属于同化和分离模式；（2）流动儿童的社会认同及适应模式在性别、家庭经济地位、来京时间、教育安置方式等因素上存在显著差异；（3）城市认同对社会文化适应和心理适应均有正向预测作用，老家认同仅对社会文化适应有负向预测作用；（4）城市认同在教育安置方式与社会文化适应、心理适应间均起部分中介作用，而老家认同仅在社会文化适应上起部分中介作用。

英文摘要：

Based on cluster sampling, 1 164 migrant children in Beijing have been selected to participate the survey in the aspects of resident identification and native identification. The study aims to investigate the characteristics, influencing factors and the migrant children＇s urban adaptation, and also to examine the mediating effect of social identification between migrant children＇s enrollment allocation and urban adaptation. The result shows as follows： first, the assimilation mode and separation mode of social identification are the most common adaptation mode exhibited by migrant children; second, the social identification and adaptation mode of migrant children vary with some demographic variables, such as gender, their social economic status, the duration of residence in Beijing and the types of school they enrolled; third, resident identification could positively predict both social cultural adaptation and mental adaptation, while native identification can only predict social cultural adaptation negatively; forth, resident identification has partial mediating effect between enrollment allocation and both social cultural and mental adaptation, while native identification can only partially mediate the relationship between enrollment allocation and social cultural adaptation.
