钢铁工业是国民经济的重要基础工业，但近些年来其物质投入与价值产出非常不匹配。本文基于系统科学理论和方法，建立了钢铁工业物质流与价值流动态耦合模型，对其物质流和价值流耦合状况进行研究。1991～2011年我国钢铁工业的耦合协调发展变化较大，1991～1996年钢产量在1亿吨以下，耦合协调水平较低，1997～2004年钢铁工业环比增速最高达27％，是这21年中增长最快的时期，物质流和价值流协调发展，2005～2007年铁矿石价格连年攀高，钢铁工业物质流与价值流耦合进入低级共生阶段，2008～2011年钢铁产能严重过剩，行业进入再生发展阶段。

Iron and steel industry has been China's important fundamental industry in economy for the last decade , but recently the-value output mismatches the material input a lot . Based on the theory and method of system science , this article establishes the dynamic coupling model of material flow and value flow in iron and steel industry . From 1996 to 2011 , the coupling and coordination of iron and steel industry in China varies greatly :from 1991 to 1996 the steel output was under 100 million tons and the degree of coupling was low ;1997~2004 the steel growth reached 27% for the highest level , the material and value flow coordinated well ;2005~2007 the price of iron ore soared , which resulted in low -grade symbiosis , and finally 2008~2011 over capacity became a big problem , the industry walked into the regeneration stage .
