This paper examines on the one hand the proximity effects on ICT firm’s innovation, on the other hand it verify the similarity of technological and non technological innovation determinants. Thus, we recall the theoretical background of proximity effect on Co-localized firm’s innovation from both geographical economy and neo-institutionalism work. The results of a logistic regression, performed by a collected data from 58 Co located ICT firms within Elgazala technology Park in Tunis, shows that firm concentration, socio-economic, organizational and cognitive factors exert a favorable effect on technological and non-technological innovation. However, empirical results confirm that innovation determinants differ depending on whether it is technological or non-technological.
