Abstract: The rapid development and popularization of the Internet has brought about new opportunities and challenges to the citizenization of migrant workers. Yet，the Internet，as well as other information and communication technologies，is，after all，a technological means and instrument for people to achieve specific aims. Whether the Internet plays a positive or negative role depends on the way of the subject to use it. Based on questionnaire survey data collected in four cities in 2016，an empirical analysis of the situations of migrant workers using the Internet and the influence on their citizenization shows there exist two digital gaps. The first one，the gap of accessibility，is no longer an urgent issue for migrant workers，but the second digital gap，that of use，exists in reality and evidently influences the urbanization progress of migrant workers. Specifically，the Internet availability rate in the migrant worker community is relatively high，up to 90 percent；they mostly use the Internet for chatting，news browsing，and entertainment，but seldom for promoting their vocational development and technical levels. While the use of Internet can elevate the citizenization level of migrant workers，it is not true that the longer time one uses the Internet， the higher one’s citizenization level is. Using the Internet as an instrumental platform and a channel of acquiring information has a positive effect on migrant worker’s citizenization，while using the Internet as an interactive entertainment has no evident effect for their citizenization. Therefore，improving migrant workers’network attainment and optimizing their ways of using the Internet have a positive significance for promoting their citizenization，besides further enhancing their Internet accessibility.
