An Integrated Analysis of Technology Acceptance Behaviour Models: Comparison of Three Major Models

With the development of technology, the company begins to introduce various kinds of technological equipment. Hence, technology acceptance behaviours have become a famous issue. Researchers also construct many technology acceptance behaviour models. Among them a series models in which extended from Theory of Reasoned Action are the most complete. There are also other models construct from different theories, such as Innovation Diffusion Theory, Social Cognitive Theory, and Motivation Theory. However, various models make researchers more difficult to choose and construct a research model. Therefore, this study selects 3 most representative models which include Technology Acceptance Model, Combined Theory of Planned Behaviour and Technology Acceptance Model, and Unified Theory of Acceptance and Use of Technology. Comparing 3 models' richness and parsimony can help to identify their characteristics. According to the research results, the complex models do not necessarily have better explanation ability. On the contrary, the Technology Acceptance Model concurrently has advantage of richness and parsimony.
