A significant capacity increase has been achieved in the last 17 years when it comes to OIZs which provide site allocation and infrastructure facilities for entrepreneurs. This research has been designed to seek answers to the question “In addition to the infrastructure facilities they have been offering, how can OIZs contribute to the firms operating within them to become more innovative and digitalised?” Following the preliminary works and the field research, it has been shown through data that OIZs can contribute more to the competitiveness of firms. This publication presents model suggestions that will trigger the transformation of OIZs into a new structure which will assume an interface mission to increase the innovativeness, productivity and digital capacities of the firms operating in their regions.
