Abstract: Based on the survey data collected from 1669 college students representing 44 classes, the effects of class environments on internet altruistic behavior of undergraduates and its relationship with internet-behavior preference were tested. Hierarchical Linear Model (HLM) results revealed that: (1) Under the control of genders and internet experiences, internet-behaviors preferences of undergraduates could significantly predict the score of internet altruistic behavior. (2) Significant differences among classes existed in internet-games preference affecting internet-support and internet-sharing, computer-mediated communication preference affecting internet-support and internet-information preference affecting internet-reminding. (3)The girl rate and the average self-esteem in class could positively predict class mean difference of internet-support. (4) The average online time every week and the average self-esteem in class could significantly modulated the relationship between computer-mediated communication preference and internet-support.

Key words: internet altruistic behavior, internet-behavior preference, class environment, hierarchical linear model, college students.
