China’s urban–rural relationships have been changed dramatically by the intensifying population flows, especially in urban agglomeration regions. This study contributes to the interpretation of urban–rural integration mechanisms in urban agglomeration by constructing a conceptual framework of migration-related resource flows. Taking the Wuhan urban agglomeration as an example, migrants’ farmland arrangement, migration pattern, and social integration have been investigated to uncover the spatial and temporal characteristics of the urban–rural interaction, based on the data from the China Migrants Dynamic Survey in 2012–2017. The findings indicate that the farmland circulation in the Wuhan urban agglomeration was generally low, but slightly higher than that of the national average. The central city, Wuhan, had a high degree of family migration and social integration, indicating stronger resource flows in developed areas. However, its farmland circulation level was lower than that of non-central cities. The unsynchronized interaction of resources in urban and rural areas should be taken seriously, especially in areas with a relatively developed urban economy. The advantages of the central city in absorbing and settling migrants confirmed the positive impact of the urban agglomeration on promoting urban–rural integration.

The social integration in host cities of China’s migrant population and its determinants has received much attention from researchers. However, few have directly addressed the family migration in differentiating migrants’ social integration. This study employs descriptive statistics and multivariate regression to explore the social integration across different family migration types, based on the data of China Migrants Dynamic Survey 2013 and 2017 in Wuhan metropolitan area. The findings show that the family migration in Wuhan metropolitan area is prevalent, and the central city Wuhan has advantages both in the proportion of whole-family migration and the scores of migrants’ social integration. In addition, the migrants’ family migration is significantly positively associated with their social integration, but the effect is variance in the regression models of social integration’s four dimensions. The findings reveal the Wuhan City’s leading position in promoting migrants’ social integration within the Wuhan metropolitan area. Furthermore, migration with more family members has higher levels of integration in economy and public service. This implies that the convenience provided by inflow cities’ government for family migration is crucial. To provide high-quality public services is of great significance to attract and retain migrants and then promote their overall social integration.
