The relation between city size and wage inequality is well established for Western countries. This paper finds that city size-wage premium exists across Chinese cities to a lower extent than the Western world. Further, using a simplified model on the Chinese Household Income Project survey data, we find that the city size-wage premium varies with difference in skills among urban citizens. The variation amounts to 50% more for the high-skill workers compared with their low-skill counterparts. Moreover, owing to the presence of segmented labour market, the patterns of city size-wage premium and city size-wage inequality premium are notably different for the migrants, who receive a much lesser wage than the citizens and do not experience wage variation owing to their skill heterogeneity.
