모바일 인터넷 서비스 수용에 대한 실증적 연구 : 기술수용모델을 중심으로

Abstract

Recently as fervor of the wired Internet has cooled off to some point. The mobile internet service is gaining great interests from various fields as a new communication medium. Users, who are already experienced with the wire internet and cellular phones, have high expectations on new capabilities provided by mobile internet, thus making optimistic predictions on its extent of use. However, in spite of high expectation of wireless internet service possible, it is important to find out factors that influence use of wireless internet. Previous study results suggest that identifying factors influencing technology acceptance is important in order for the new technology effectively accepted in the market. Thus, this study attempts to investigate factors that influence the use of mobile internet on the base of technology acceptance model. Technology Acceptance Model(TAM) is one of the model that are being frequently used in recent studies in information systems. TAM explains user's technology acceptance as a process where perceived usefulness and ease of use determines users attitude toward the technology. and this attitude finally leads to the actual technology use. Although mobile Internet has substantially different characteristics from other task-oriented information system, it is new technology whose acceptance can be affected by many factors be meaningful to conduct an empirical research examining how difference in technology characteristics affect the use of technology in what ways, and mobile internet service would be appropriate for this subjects. The purpose of this research model is to find out that external variables would not directly increase the acceptance of mobile internet service, but the would do through users perceived usefulness and ease of use. Thus users perceived usefulness and ease of use serves as a mediating variable between external variables and a dependent variable in our research model. The result shows that external variables have significant effects on the use of mobile internet service acceptance. this result is coherent th Dais'(1993) work that external variables representing system characteristics do not have direct influence on the system acceptance.
