Abstract: In the context of urbanization, how rural migrants integrate into the city and achieve identity change remains a key issue. This paper finds that in addition to the Relationship-Enclaves Pattern and the Individual-Family Separation Pattern, there is also a family and business integration urbanisation model of rural migrants, that is, using self-employment to earn a living in urban space and achieve the goal of staying together and developing as a family in the city. This study is based on an analysis of 44 small family business cases in N community of W city. It finds that family labor, dwelling size and family networks are all conducive to business, and the advantages of family and business integration model are also embedded in the different stages of family reproduction, enhancing reproduction and opportunities for the next generation to acquire urban residency. This paper suggests that the intergenerational relay and family values contained in the Family and Business Integration Model serve as a common mechanism of rural migrant's urbanization, underlining the value foundation of family as a whole and its practical significance in urban space. Thus, family and business integration constitutes a vital alternative urbanization model for rural migrants. It is not an evolutionary relationship in which one practice model replaces another, rather multiple models coexist under different circumstances. Nor is it one trend overtakes another, rather different groups seek the optimal settlement in a semi-open and semi-closed institutional environment. Therefore, this paper emphasizes the significance of family and business integration as one of many rural migrants' urbanization approaches and its discussion helps a better understanding of the urbanization of rural migrants in China.

Key words: integration of family and business, urbanization of rural migrants, intergenerational relay race
