ABSTRACT

Mobile cloud computing is the combination of cloud computing and mobile networks to bring benefits for mobile device users, network operators, as well as cloud computing providers. The explosive growth of mobile cloud computing becomes a powerful trend in the development of new computing infrastructure as well as communications business and security fields. In South Korea, mobile cloud computing market is becoming more and more competitive, and the interest in mobile business is increasing. Most of the studies on mobile cloud services, however, have been conducted from the viewpoint of technology and system engineering, and few studies are conducted from the users’ viewpoint. In this sense, this study is aimed at proposing a new research model in which the influence factors of mobile cloud continuance usage intention (i.e., perceived privacy, perceived security, and perceived enjoyment) affect TAM factors (i.e., perceived ease of use and perceived usefulness) positively, leading to information systems continuance usage model eventually. This study developed a research model to explain the continuance usage of mobile cloud services and collected 182 survey responses from the undergraduate students who had experiences with such mobile cloud services. To prove the validity of the proposed research model, PLS analysis is applied with the valid 182 questionnaires. By employing the PLS technique, the measurement reliability and validity of research variables are tested, and the path analysis is conducted to carry out the hypothesis testing. In brief, the finding of this study suggests that the influence factors of mobile cloud continuance usage intention affect TAM positively, and continuance usage of mobile cloud services as well.

KEYWORD
