The factors leading to these dissimilarities have been investigated in several researches. In this paper, the factors affecting the IT diffusion and acceptance in Iranian organizations have been discussed based on the EOT Model (Environment, Organization, and Technology Model). The data have been gathered through survey of more than 84 Iranian firms during 2010 to 1012. Also, a case study is applied for justifying the research results. The results show that the factors such as: managers' perception of IT advantages and challenges, The size of organization, stability of managers, suppliers readiness for IT usage, have a positive influence on IT acceptance in the organizations. However, the relation between the intensity of competition in the industry and IT acceptance is not confirmed. Finally, some policy implications for IT diffusion in Iran have been discussed. %U https://jtdm.irost.ir/article_59_f50e0fbaacaf89a2f41921412f870864.pdf
