摘要
利用集中度 (CRn)和赫芬达尔指数 (HI)计算公式 ,对国内外钢铁工业几十年来的大量数据进行分析研究 ,定量分析我国钢铁工业集中度现状 ,指出在我国年产钢量占世界年产钢量比率快速上升、世界钢铁工业集中度连年上升的情况下 ,我国钢铁工业集中度在下降 ,而且有下降加速的趋势 ,指出我国钢铁工业集中度亟待提高。
Using the calculating formulas of concentration ratio (CRn) and Herfindal Index (HI) a large number of domestic and international data of iron and steel industry has been studied. After quantity analysis about present situation of the concentration ratio in China, the results show that ratio of internal steel output to world output rises quickly. Concentration ratio of international iron and steel industry rises for years running while it presents opposite situation in China and the falling trend is accelerating. It shows that a significant promotion of concentration ratio of iron and steel industry in China is urgently demanded.
