ABSTRACT This paper constructs an urban integration index system of the migrant population to compare differences in the level of urban integration among different ethnic groups on the Qinghai-Tibet Plateau. The study finds that Tibetan migrants have the highest level of urban integration, followed by Han and then Hui migrants. The migrants of each ethnic group have their own advantages in urban integration among the different dimensions used in this study. Han migrants have the highest level of economic integration, Tibetan migrants have the highest level of social participation, and Hui migrants have the highest level of psychological and cultural integration. There are also regional differences, with the level of urban integration of migrants in Qinghai Province being higher than that of migrants in the Tibet Autonomous Region. From the perspective of the different dimensions of integration, the economic integration of migrants in Qinghai Province and the social participation of migrants in the Tibet Autonomous Region have integration advantages. In addition, factors affecting the urban integration of the migrant population of different ethnic groups share some similarities and have some differences.
