Explaining variations in national fleet across shipping nations

Many studies on national shipping attribute the declines in national fleets of developed economies to the lack of comparative advantage, but little has been done so far to identify factors contributing to countries’ shipping comparative advantage using a systematic approach. Although shipping markets are highly international and competitive, it is not clear whether tonnage owned by countries is governed by country-specific factors. This paper seeks to explain variations in nationally owned fleet across shipping nations. The main variable of interest is national fleet tonnage owned by country of domicile as opposed to registered tonnage. The results of econometric analysis using data from 84 shipping nations indicate that various country-specific factors do indeed contribute to variations in fleet tonnage across shipping nations, albeit at different levels of significance. Financial market development, external trade, ship registration, shipbuilding and shipping history appear to have the most significant impact, followed by the level of development and technology and maritime policy. Based on the results of analysis, implications for policy and future research are also discussed.
