Based on the questionnaire data from college students in Guangdong，this paper carried out empirical research with Multinomial logit model on the issue of college students’ hospitalizing behavior and its influencing factors. The results show that age, gender, grade and health condition of college students have significant impact on their hospitalizing behavior, that the college students with elder age, female, low grade and poor health condition are more possible to choose to be hospitalized, and that health insurance, household registration and living expenses have no statistically significant influence on college students’ hospitalizing behavior. Therefore, the government department should reinforce campus and community health service system to meet the hospitalizing demand of college students by consolidating the propaganda and education as well as the perfection of the medical insurance system of the college students to boost their rationally hospitalizing behavior. 
