Abstract: 【Objective】 Studying the influence of city scale on the subjective relative poverty of floating population,and provide more empirical evidence for the choice of floating population flow and urban development. 【Method】 Based on CLDS 2016 data, we analyzed and tested the impact of city scale on the relative poverty of floating population and its mechanism from a subjective perspective by using econometric models such as Probit and IV Probit. 【Result】 The larger the scale of the city, the less likely it is for the floating population to fall into subjective relative poverty. At the same time, the floating population of the old generation and those with lower levels of education can all benefit from the urban economies of scale, that is, the expansion of city scale can significantly reduce their possibility of falling into the subjective relative poverty;The city scale does not have a significant impact on the subjective relative poverty of the floating population of the new generation and the floating population with a higher level of education. In addition, city sce mainly reduces the possibility of floating population falling into subjective relative poverty by reducing the possibility of unemployment of floating population and improving their income satisfaction. 【Conclusion】 Based on the analysis, in order to alleviate the relative poverty problem and continuously improve the living standard of the floating population, we suggest to vigorously build small and medium-sized cities, pay equal attention to basic education and vocational education, promote the reform of the salary system, and make full use of the government's regulation and supervision functions.
