Drawing on nationally representative data, this paper compares and analyzes working hours among urban residents in the host society, and urban-to-urban migrants and rural-to-urban migrants.The analytical results illustrate that the average weekly working hours and the probability of working a standard hours(36-45 hours) among the three segments of population differ from each other significantly, and all migrants;regardless of hukou, work longer hours, but have a lower likelihood of working a standard hours than local residents.Among migrants, rural-to-urban migrants, doubly disadvantaged due to rural hukou and being outsiders, work the longest hours, and are least likely to work standard hours.Such findings suggest that both hukou types and inside-outside locations of hukou are important for migrants' access to labor protection, and that the location of hukou seems more important than hukou type, implying that labor protection should better cover all segments of the population, particularly rural-to-urban migrants.
