기술수용모형 관련 요인들간 관계에 대한 통합적 이론모형

The acceptance of information technology(IT) or information systems(IS) has been the subjects of great deal of research in the last two decades and now also has been continuously studied. The objective of the study is to analyze with integrated view the key factors of previous model and analysis and is to construct the relationships between external factors and basic factors in explaining and predicting technology acceptance. The researcher try to conceptualize external factors to affect on the intention to use or/and actual use of IT or IS and reformatively use the voting count method to construct the integrated theoretical model of technology acceptance model(TAM). The integrated theoretical model are composed of three dimension according to comprehensive taxonomy, that is to say external factors(exogenous independent variables), perceived ease of use/perceived usefulness (endogenous mediating variables), intention to use or/and actual use(final dependent variables). The study on the key factors to affect on the intention to use or/and actual use must include the perceived ease of use/perceived usefulness. Because it is based on the Davis's original model for parsimoniousness and theoretical validity of an integrated theoretical model(systematic descriptive model). Twenty-two factors of thirty factors and thirty-eight paths of one hundred fifty paths(perceived ease of use → perceived usefulness is very important path) are used to construct the integrated theoretical model. Limitations of the study and suggestions for future researches are discussed.
