Abstract: Interethnic marriage can be viewed as a social relation system characterized by a set of ethnic groups and their intermarriage ties. Therefore, Interethnic marriage data are relational data. This paper is the first attempt to use social network analysis methods and tools to depict the structural characteristics of Interethnic marriage relations in China. Based on 2010 census data, this research suggests that a national Interethnic marriage circle centered on the Han nationality has formed. Meanwhile, there are 8 local intermarriage subcircles which consist of different minority ethnic groups. Such structure demonstrated a diversified but integrated Chinese nation. Social network analysis is a reliable and valid approach to understand the structure of Interethnic marriage relations. The graphical presentation of social networks, centrality measurement and community identification technology are especially useful.

摘要： 族际通婚数据属于典型的关系数据，可视为由各民族与其他民族通婚联系形成的关系体系。因此，社会网络分析提供的一整套方法可作为族际通婚研究的方法工具，以便利地刻画通婚关系的结构特征。基于2010年第六次全国人口普查数据，首次尝试将该方法用于考察和分析中国各民族族际通婚的结构性特征。初步应用揭示，中国形成了一个以汉族为中心的大的全国族际通婚圈，同时存在少数民族间凝聚力明显有别的8个地方性子通婚圈，该结构特征是中华民族多元一体格局的直观体现。可见，社会网络分析是揭示和认识族际通婚关系结构的可靠且有效方式，其中，社会网络的图形呈现、中心性测度和社群识别技术可为族际通婚关系的分析提供直观和详细的补充信息。
