Abstract: The gender wage gap is a common phenomenon in the urban labor market,and the rapid urbanization process has brought city size wage premium to workers due to the expansion of the scale of the city,but the degree of obtaining city size wage premium to different workers varies.So,does our country's urbanization process help narrow the gender wage gap? Based on the data of latest 2017 China Migrants Dynamic Survey (CMDS) with 247 cities,this paper constructs a two-step regression model to test whether the size of the city affects the level of gender wage gap.The empirical results show that the male labor force in 233 cities has a higher salary level,but the female labor force obtains a higher city size wage premium than the male labor force,which reduces the wage gap with the male labor force in increment.In specific,the city size increases by 1%,the city-scale wage premium received by women is 0.097% higher than that of men.It can be seen that the gender wage gap will decrease as the size of the city expands.In this paper,changing the empirical analysis method and the micro data sample have been tested for robustness,and the empirical results are proved robust.This research provides a new perspective and new answer to explain the gender wage gap in China.
