IDT-TAM integrated model for IT adoption

Two classical theories, the technology acceptance model (TAM) and the innovation diffusion theory (IDT), were integrated into a model for analyzing individual information technology (IT) adoption behavior. In this IDT-TAM framework, the perceived characteristics of innovation are categorized as subjective evaluation, objective conditions, and interaction factors. The cognitive mechanisms that drive user IT acceptance are analyzed based on the patterns through which these characteristics influence individual user IT adoption behavior. The model was tested using an empirical survey regarding the adoption and use of e-mail in China. Results from a structural equation model analysis illustrate that the model provides meaningful insights for understanding, explaining, and predicting the IT adoption behavior of Chinese users.
