Cloud Computing Adoption by Small and Medium Enterprises Based on DOI and TOE Theory

In order to identify the key factors influencing small and medium enterprises (SMEs) adoption of cloud computing, a cloud computing adoption model for SMEs was constructed based on the diffusion of innovation (DOI) theory and the technology-organization-environment (TOE) framework. A questionnaire-based survey was used to collect data from 136 firms (SMEs) in central China. The results showed that top management support, technology readies and regulatory support have a significant influence on the adoption of cloud computing and external pressure has an indirect effect on it, however relative advantages, complexity, perceived risk, firm size and sensitivity & criticality of business have no significant influence on it. The research help firms consider their evaluation and investment for cloud computing project and also offer service providers with a better understanding of what effects cloud computing adoption, with relevant insight on current designs and promotions.
