The impact of urban housing and city welfare on the rural migrants’willingness of household registration，on the basis of 2017 China Migrants Dynamic Survey，is explored. It is found that, with the exception of a few higher-welfare megacities，owing urban housing has negative effect on rural migrants’ intention of household registration. A higher level of city welfare is a promotion of migrant workers’ willingness to settle in city and this promotion is amplified by house purchase in the city. A sub-sample survey by age, education, region and occupation indicates that those highly educated or employers among the migrant workers are even more reluctant to settle down after owing urban housing. This moreover highlights that those who are more able to obtain hukou are less likely to have their household registered in cities and those who are eager to settle in city，by contrast，are generally frustrated workers without urban housing and corresponding capacities. Further comparison between the influence of urban housing on rural migrants’ and on urban migrants’purpose of household registration, and between the impression of owing urban housing to the intention of household registration and permanent residence， stresses that settling in the city is not the goal of migrant workers，and staying in higher welfare cities and keeping urban housing and rural hukou are their aspirations. In this connection, the citizenization policy of rural workers in the 14th Five-Year Plan period should make some adjustments．The selection criteria of hukou promotion targets ought to change from capacity-based priority to demand-based priority，the various urban public services and city welfare ought to be continuously improved and the target of migrant workers’ citizenization ought to be readjusted from citizenization by hukou to citizenization by permanent residence．
