Abstract
To supply the fundamental information for estimating future steel stocks, this research estimated the goods-wise steel stocks in the world. The world was divided 35 regions and goods were disaggregated into 23 kinds of goods based on its use and steel input unit. Firstly steel stocks with 5 classifications were estimated by dynamic model from 1900-2005. And with regards to the year 2005, these stocks were disaggregated into 23 classifications by information of goods stocks.<br> The results show that global steel stocks was 14.0 billion ton in 2005. The share of each goods was 34% for buildings, 24% for civil engineering structures, and 22% for machinery. The stocks in developed countries were mostly stabilizing after the 1980s and their share was 66% of global stocks in 2005. The range of steel stocks per capita in developed countries was 4.9 -10.6 ton/capita and that in developing countries was almost no more than 3 ton/capita. The numerousness of stocks for building and transportation infrastructure was a main factor in the regions whose stocks were large.
