Informatization, as a trend in the world's development nowadays, has become an important force to promote economic and social reforms. Since 1990s, information technology reforms have advanced dramatically. Along with the constant development of the information industry as well as the popularization of information network, informatization has been viewed as the dominant characteristics for the economic and social development of the whole world. New technologies have spread network entertainment by combining traditional entertainment forms and network. Young people, who value Internet a lot, have accepted network entertainment as an indispensable part in their life. Accordingly, any boycotting attitude toward their network entertainment may exert hindering influences on their development. As a result, it is quite necessary to have an overall understanding on college students' network entertainment activities and raise corresponding countermeasures so as to guide them to be positively affected and to achieve sound development as well. The questionnaire method is adopted in this research to investigate students from 9 classes of 3 different colleges of Changchun University of Science and Technology.
