This thesis has been elaborated after a thorough study of domestic and foreign bibliography, so that to justify the market shares of Greek ports, as well as the concentration that exists in Greek port industry for the three main cargo categories, a) liquid bulk, b) dry bulk and c) containers In order to draw a conclusion on the above, an overview of the modern trends in global maritime industry was made, in addition to the evolution of the seaborne trade the last years. Subsequently, the trends in modern port industry of cargoes are demonstrated, combined with the development of transshipment hubs and the port evolution both in technological aspect and in horizontal / vertical integrations. On a later stage, the Greek port industry is analyzed, based on the institutional framework, supply and demand. Following the collection of relevant data on the previous mentioned categories, the market shares for all three basic markets for the period of 2014-2016, are demonstrated. Moreover, the concentration indices a) Concentration Ratio and b) Herfindal-Hirschman (HHI) are being applied, in order to justify the concentration volume of the three markets in the Greek port industry. In conclusion, the liquid bulk market seems to be highly concentrated, something that is justified because of the existence of refineries in the areas next to the ports. The dry bulk market is not so concentrated, due to the fact that much more ports are involved in this type of cargo, basically due to many industries that are being supplied. Finally, in the container market, Piraeus port seems to have great monopoly power in the national inland, however, the port faces strong competition in the wide Mediterranean area, especially by ports that are located near the sea road between Suez and Gibraltar.
