Based on the analysis of monthly income and hourly income，this paper finds that，although in recent years，migrant worker’s income has kept increasing，the wage discrimination still exists. That is to say，at the same education level，agricultural workers still receive lower wage than their counterparts in non-agricultural industries. Furthermore，in manufacture sector，when controlling education attainment，workers in east region still receive higher wage than those in western areas which is the reason why the trend of migration from middle and western areas to east areas continues.
