The aim of this article is to discuss the role of the blue economy, also known as “blue growth”, as related to the traditional maritime economy in Pomorskie Region. The potential of the latter is comprised by transport infrastructure centres consisting mainly of two ports – in Gdańsk and Gdynia – with a fundamental role for the national economy. These ports in recent years have seen intensified growth as evidenced by their increased throughput – mainly in terms of containerized cargo volumes. The modern approach to the maritime economy is based not only on heavy, large-scale investment in the infrastructure and cargo handling capacities, but also on sustainable development related to sophisticated technology and energy saving. The importance of the latter has been highlighted by Pomorskie Region’s four Intelligent Specializations aimed at ensuring sustainable growth in the region. Although the maritime economy is the focus mainly of Intelligent Specialization No. 1 “Offshore, port and logistics technologies,” there is in fact a synergy effect which has led to establishing mutual relations between all intelligent specializations. This approach combines the shipbuilding industry with energy production and biotechnology through innovative solutions. Meanwhile, IT supports logistics and marine tourist helps modernize and revamp sea ports as well as stimulates Pomeranian shipyards to manufacture specialist ferries and passenger ships.
