基于多维相对贫困改善视角，运用2017年中国流动人口动态监测调查C、D卷和对应4个城市下辖26个区（县、市）的匹配数据，探究了城市公共服务提升农民工城市永久迁移意愿的作用机制。结果表明：多维相对贫困强度的上升抑制了农民工城市永久迁移意愿，城市公共服务改善了农民工以城市居民为参照系下的多维相对贫困进而提升了其城市永久迁移意愿；异质性检验发现，城市公共服务主要改善了有居住证、老一代、省内流动以及“为了子女有更好教育”留城的农民工的多维相对贫困进而提升其城市永久迁移意愿。

From the perspective of multi-dimensional relative poverty improvement, this paper uses the matching data of the China Migrants Dynamic Survey Volumes C and D in 2017 as well as twenty-six districts (counties and cities) among four corresponding cities and explores the operation mechanism of urban public services to enhance migrant workers’ permanent migration willingness. The results show that the rising intensity of multi-dimensional relative poverty inhibits migrant workers’ willingness to permanent urban migration, and the urban public services can improve migrant workers’ multi-dimensional relative poverty under the reference frame of urban residents; thereby enhancing their urban permanent migration willingness. The heterogeneity tests find that urban public services mainly improves multi-dimensional relative poverty of migrant workers with residence permits, of the elderly generation, the mobility within the provinces as well as for better education for their children, thereby strengthening their willingness to permanent urban migration.
