With the development of new urbanization, the policy environment of floating population has been greatly improved, and their social integration status is almost the same. This paper regards the floating population as a dynamic agent in the differential pattern. Using the dynamic monitoring data of the floating population in 2010 and 2017, it examines the impact of individual ability and social network on social integration and its effect changes. The results show that since 2010, the impact of education years and income on social integration is not obvious, but the impact of employment status on social integration is increasing. Compared with 2010, family mobility based on blood ties in social networks has a significant impact on social integration and its effect is increasing; as a special geographic link, the relationship between fellow townsmen has a positive impact on social integration, but the effect is unchanged; and the impact of other local relationship networks on social integration is no longer significant. In addition, household registration, social exclusion and urban size are still important factors affecting the social integration of floating population. Therefore, while paying attention to the individual development of the floating population, we can help them realize family reunion and promote the formation of the relationship network between the inflow areas, so as to better realize social integration.
