As previously mentioned, the entrepreneur constitutes one of the key factors in the adoption of
ICT by SMEs. In regard of this, the innovation and entrepreneurship literatures have long been
interested in the following question: What are the differential entrepreneur’s features that most people do not have? Apart from financial and an opportunity cost-based rationale, the literature analyzing this issue has examined three different categories of explanations: (1) basic demographic factors such as age, ethnicity and gender, (2) training and experience effects, and (3) psychological differences between individuals. Our purpose here is to briefly review these explanations to provide context for understanding the importance of the entrepreneur in the ICT adoption process by SMEs.
