• A STUDY ON THE ESTIMATION OF GLOBAL IRON AND STEEL CYCLE

抄録

Iron is one of the essential materials for industries and consumers in modernized society. On the other hand, steel industry is the largest energy consuming industry in the world and one of the mostimportant sources of CO2 emissions. Thus, the projection of iron supply and demand is valuable consideringlobal warming. Though the information about steel is published by IISI etc., no statistics and articles have revealed global iron supply, demand, flows and stock including the iron contained in commodities. As this background, we developed the “Global Iron and Steel Account Table” which is the basic information for projecting the future iron supply and demand. Moreover, we estimated the iron flows under the accounting system. We used the estimation method proposed by Fujimori et al.(2005) for the estimation. In this article, we show the global iron flows in 2001 and analysis of the data. We mainly looked at three points in this database as followings. First is that we could categorize the regions based on the net imports and exports of commodities and we can see the structure of international division of labor. For example, Japan and Germany are the net exporter of both of steel and final commodities. On the other hand US and UK are the net importer. The second is that each region's iron accumulation has direct relationship with GDP. It means that increase of GDP can accelerate the increase of accumulations at any countries. The third is that when it comes to the trade of iron scrap, developed countries and the former USSR are net exporters and developing countries, especially Asian countries, are the net importers.
