Abstract

The purpose of this study is to define determinants of VoIP user acceptance and to verify significant causality among latent variables - performance expectancy, effort expectancy, cost expectancy, social influence, facilitating conditions, behavioral intend, use behavior - based on UTAUT model. We presented the expanded hypotheses including the new factor, cost expectancy and analyzed the moderating effect of user age, gender and usage experience variables. For a accuracy of predicted results, we focused on survey analysis with 641 real user samples. Compared to previous studies, it is meaningful that this research verified the conceptual difference between behavioral intention and usage behavior. As a result, all proposed hypotheses accepted and moderating effects are supported significantly in age and use experience moderating variables.

본 연구의 목적은 첫째, 인터넷전화(Voice over Internet Protocol)의 사용자 수용에 미치는 결정요인을 정의하고, 둘째, 수용 이론들의 통합모형인 UTAUT를 기저모형으로 하여, 성과기대감, 사회적 영향, 노력기대감, 사용촉진조건, 행위의도와 사용행위 등의 잠재변수 간의 복합적인 인과관계를 검증하는 것이다. 셋째, 비용기대감 변수를 새롭게 정의하여 연구가설에 포함하였고, 각 변수들 간의 경로에 영향을 주는 조절변수로서 사용자 연령, 성별, 경험기간의 조절효과를 분석하였다. 또한, VoIP의 실제 사용자 641명을 표본 조사함으로써, 행위의도와 사용행위 변수 간의 개념적 차이를 명확히 구분하여 보다 정확한 분석 결과의 향상을 도모하였다. 사용자 수용에 대한 기존 연구들은 사용행위 변수를 검증할 때, 실제 사용자뿐만 아니라 긍정적인 행위의도를 가진 미래의 잠재적 사용자를 포함시키는 사례가 많았다. 분석 결과, 제시한 모든 연구가설이 채택되었으며, 조절효과에서 연령이 성과기대감, 사회적 영향과 행동의도 간에, 경험기간은 사용촉진조건, 행위의도와 사용행위 간에 정의 관계가 성립하였다.
