Abstract Against the backdrop of globalization and rapid urbanization, increasing differences between various social groups in cities, particularly racial and ethnic groups, have been witnessed due to their diverse socio-cultural backgrounds and daily-life habits. The present study summarizes the existing Western and Chinese literature on racial/ethnic residential segregation. It concludes that, echoing the "mobilities turn" of urban studies, more and more writings on socio-spatial segregation have adopted the new mobilities paradigm by addressing the limitations of conventional residential-based perspective. Specifically, while past studies mostly conceptualized socio-spatial segregation in terms of residential locations (the extent to which members of different social groups live apart) through the use of census data, such conventional residential-based perspective of segregation ignores people's experience of segregation in the daily activity locations other than residential neighborhoods, thus evoking increasing scholarly attention to the analyses of segregation in individual activity spaces. Four research foci can be identified from this new strand of studies, namely intergroup difference in activity-travel behavior, measurement of racial/ethnic segregation from an activity-space perspective, mobility disadvantage of ethnic minorities, and hybrid geographical analyses of the subjective experience of activity-space segregation. Through summarizing the contributions and limitations of the existing studies, the present study proposes a new, integrated research framework on ethnic socio-spatial segregation through the perspective of space-time behavior, especially the time-geographic discourse on space-time constraints as an effective theoretical lens to decipher the roles of ethnic collective routines in shaping the minorities' experience of segregation. Such a framework is conducive to better comprehending of socio-spatial segregation in the transitioning Chinese cities, as well as more insights into the everyday life and sociospatial integration of different ethnic groups (especially the ethnic minorities).
