Abstract: With the transition of China from a settled society to a migrating one, the rational choice of employment cities by the largescale migrants has a long term impact on the urban wage premium. Meanwhile, urban wage premium also affects labors choice of cities. Using the dynamic monitoring data of floating population in 2017, this paper built a disposal effect model with endogenous individual choice, and identified the existence of urban wage premium in China. Labors heterogeneity and urban characters had significant impacts on the choice of cities. By controlling the endogenous selection bias, we found that the wage premium of megacity behemoths and megacities became larger, while the large cities premium vanished. Small and medium cities had more competitive wage than large cities. These results, caming from the rational choice of labors, suggest that differentiated development policies should be implementd to realize the overall optimization and internal coordination of the urban system.
