Since the reform and opening up,the gender wage income gap of migrant workers has shown a trend of widening,and the development and use of the Internet has brought new possibilities to narrow the gender wage income gap of migrant workers.In this paper,the impact of Internet use on the gender wage income gap of migrant workers was quantitatively studied by using the data of China Labor Force Dynamics Survey (CLDS) in2014 and 2016. The findings are shown as follows: 1) Internet use has a significant premium effect on the wage income of migrant workers.2) The use of the Internet can narrow the gender wage income gap of migrant workers; increased Internet use can narrow the gender wage gap among middle-wage migrant workers.
