This paper explores the influences of media information, search cost, brand image and consumer attitude on authorization intention mainly by linear structural equation model (SEM). The research targets are the potential consumers in Kaohsiung City of Taiwan as the targets. A total of 660 questionnaires were released and 305 valid questionnaires were retrieved. The effective response rate is 46.21%. The study shows that media information and search cost have significant effects on authorization intention and such effects are through mediating mechanisms. The effects of media information to authorization intention go via two paths. Media information affects authorization intention via brand image and attitudes of consumers. Media information also affects authorization intention via attitudes of consumers alone. However, brand image only affects authorization intention via consumers' attitudes. Search cost can affect authorization intention.
