Technological districts are the point of contact between industrial supply chains and the related scientific research activities (e.g. maritime technologies, agrifood technologies, etc.). Through the implementation of joint research programmes, formal and informal collaborations, the activation of mixed public-private laboratories, etc., they aim to stimulate the access and use of research results by the enterprises that insist on the district itself. Technological districts are activated as an interface module for the development of an increasingly knowledge-based economy through the development of activities with high scientific and technological content and its connection with industrial supply chains in the area of reference.
