The port industry was often criticized for the lack of innovation. However, more recently, key actors have gradually pushed for port cities to become innovation hubs. The rise of blue economy in national and international agendas has demonstrated that port cities have a key role in the future of new productive activities related to the sea, and port authorities need to embrace new roles, dynamizing local networks, building on their role as a central figure in new economic sectors.
