Exploring long-term residence among the urban floating population is crucial to understanding urban growth in China,partic-ularly since the 2008 financial crisis.By using China Migrants Dynamic Survey data for 2012-2014,China Labor-force Dynamics Sur-vey data for 2014-2016,and macroscale urban matched data,we analyzed the spatial pattern of long-term residential behavior in China's urban floating population in 2012-2016 and developed an urban spatial utility equilibrium model containing'macro'urban factors and'micro'individual and household factors to explain the pattern.The results first revealed that long-term residence is defined as ≥ 6 yr for the urban floating population in China.Second,members of this population are more likely to be long-term residents of the megacities in the three urban agglomerations in eastern China as well as of small and medium-sized cities in western and northeastern China,whereas short-term residence is more likely in cities in central China and near the three urban agglomerations.Third,urban population density and housing prices,both have a significant U-shaped effect,are main factors affecting the spatial pattern of long-term residence.
