| Summary: | 碩士 === 國立政治大學 === 資訊管理研究所 === 91 === This study aims at building a framework to evaluate the usability of Taiwan’s mobile Internet services. An initial conceptual model is first constructed by a thorough literature review. It includes four influencing constructs: User Characteristics, Backend Infrastructure, Service Provider Aspects, and Ease of Use of Mobile Appliances. With the concepts of each construct defined, a survey is then conducted to verify the relationships among the variables. The analysis results show that User Characteristics and Ease of Use are directly related to the perceived usability, whereas Backend Infrastructure and Service Provider Aspects are indirectly related to the perceived usability. This implies that users perceive the usability through the mobile appliances’ ease of use. It is also concluded that fast and stable network connection, effective products strategy, superior service level, user-friendly mobile appliances, sufficient customer support and education for users are the keys to a successful mobile Internet service.
