Abstract

The shipping industry can be explained by a growing process of concentration and centralization of tonnage. A few largest sipping company control a great deal of shipping tonnage in the total tonnage through the process of concentration and centralization of tonnage in shipping over time. It confirms that a decreasing number of operators take an increasing quantity of tonnage in the total tonnage. Thus, the extremely dualistic structure (extremely unequal distribution of tonnage) are shown not only in the shipping industry in a given country but also in liner shipping in the world. In this paper, the two countries, that is, Korea and Egypt, are compared considering the absolute size of tonnage and shipping policy in terms of concentration and centralization of tonnage in shipping. In order to measure the degree of concentration of tonnage in shipping, the quantitative measurements; the Lorenz curve and Gini coefficient are introduced But it should be supplemented with the qualitative measures of tonnage in a given country.

Key Words: Concentration and centralization of tonnage;Extremely dualistic structure;Gini coefficient;Lorenz Curve
