中文摘要：

文章以世界十大钢铁生产大国作为研究对象,分别测算了这些国家1996年至2006年钢铁产业链各环节的国际市场占有率和贸易竞争力指数。研究结果显示,中国钢铁产业在国际市场的占有率稳步提高,但中国钢铁产业的贸易竞争力仍然很弱;俄罗斯钢铁产业受上游产业能源与资源的束缚最少;而中国、日本、韩国、德国和意大利严重受到上游产业的制约,印度、巴西、乌克兰和俄罗斯钢铁产业链下游产业的贸易竞争力普遍较弱,而日本、德国和意大利的则普遍较强。

英文摘要：

Taking the TOP 10 big steel producing countries in the world as the object of study,this paper estimates international market share and international trade competition index of every link in steel industry chains from the year of 1996 to 2006,respectively.The research results show that international market share of Chinese steel industry is improving steadily,while its international trade competition capacity is still weak.Restriction on Russian steel industry by upstream industry such as energy and resources is the smallest.while the development of steel industry in China,Japan,Korea,Germany and Italy is seriously restricted by upstream industry.The International trade competition of downstream industry in the steel industry chains in India,Brazil,Ukraine and Russia is generally weak while that of in Japan,Germany and Italy is strong.
