First，this article sorts out the connotation of citizenization of agricultural migrant population，then constructs the evaluation index system of citizenization of agricultural migrant population by AHP method，and assigns weights to each index variable. The degree of citizenization of agricultural migrant population in Henan province was evaluated scientifically. In 2017，the research results showed the citizenization degree of China’s agricultural migrant population is 40.11%，and the overall citizenization degree is not high. Though further structural analysis of various indicators，it is found that material capital and human capital provide a strong guarantee for the citizenization of agricultural migrant population in the future，while psychological identity and social capital are the main obstacles for the smooth citizenization of agricultural migrant population in the future. Based on it，this paper proposes some policy suggestions to promote citizenization of agricultural migrant population，such as enhancing human capital of agricultural migrant population，eliminating employment discrimination，and improving self-identity of agricultural migrant population in urban life through formal education and skill training.
