In the Chinese context，migration is defined to be move with hukou relocation，which is closely associated with urbanization. Over the past two years，the central government has attached great importance to the urbanization progress of the registered residents. A new round of household registration system reform was launched in 2014. Based on the data of hukou registration transition in 2013，this study examines patterns and determinants of household migration and urbanization of regis- tered population. Results indicate that the difference of hukou status between rural and urban areas was the fundamental cause in holding back household migration. Moreover，migration to big cities is pre- ferred by elites，while the medium-sized cities and small towns are lack of attraction for these people.

This study attempts to provide an insight of migrant identity using the data of 2012 Migrant Dynamics Monitoring Survey in China．The Latent Class Analysis is adopted to explore the patterns of mi- grant identity．Demographical differences among different identity patterns are also examined．The results identify three patterns of migrants’identity: rejected identity，congruent identity and ambivalent identity．No significant identity difference is found between urban-urban and rural-urban migrants．Part of the migrants has ambivalent feelings about their identity．The new generation of migrants，especially the new generation of rural-urban migrants tends to reject their citizenship of the inflow cities．The distance of migration and the type of settled city are significant factors affecting pattern of migrants’identity．The prolonged duration of residence tends to improve migrant’ s degree of self-identity．Interacting and communicating with local resi- dents are important in facilitating migrant’ s self-identity．Finally，living with family enhances migrant’ s self-identity．
