Its empirical research design, framework and analysis methodology adopt the international criterion, and the target is college students, whose iifecycle and consumer behavior is right at the turning point. Based on the literature review of credit card usage behavior abroad and the consumer behavior domestically, the dissertation explore the Chinese mainland college students' "money style", credit card using and the influencing factors from different point of views, and construct the credit card usage behavior model. The study includes some innovation in the research design. It brings the notion of value into the framework, which is a representative of individual's need and ignored by the other researchers. With money attitude together, college students are divided into different money style clusters. Also, the lifecycle character of college students are not ignored, and we find that the consumer socialization does affect their attitude and behavior, dynamically. The money attitude and credit card attitude measuring instrument used in the dissertation are localized, which reliability and validity were tested by researchers abroad. As a practitioner, the writer designs the credit card using scales exploring the cardholders' intent and behavior deeply.
