【摘要】：简要分析了我国改革开放以来铁矿消费强度的阶段性变化特征,建立了铁矿消费强度的增量分解模型,应用国民经济投入产出表中数据,分时段对铁矿消费强度进行了增量分解计算和分析.结果表明,2002年前,资本形成以低于或基本等于GDP的增速增长,钢铁冶炼及加工业的铁矿消耗系数下降,致使铁矿消费强度降低;2002~2010年间,资本形成增速高于GDP增速,钢铁冶炼及加工业产出效益下降、铁矿消耗系数升高,致使铁矿消费强度大幅上升.因此,钢铁冶炼及加工业需要解决的主要矛盾是淘汰过剩的低端产能和推动产品结构升级,降低整个经济的铁矿消费强度,达到产业健康稳定发展的目的.
[Abstract]:The characteristics of iron ore consumption intensity since the reform and opening up in China are briefly analyzed. The incremental decomposition model of iron ore consumption intensity is established, and the data in the input and output table of the national economy are applied. The incremental decomposition calculation and analysis of iron ore consumption intensity are carried out in different periods. The results show that before 2002, the growth rate of capital formation was lower than or almost equal to that of GDP, and the consumption coefficient of iron ore in iron and steel smelting and processing industry decreased, which resulted in the decrease of consumption intensity of iron ore. The growth rate of capital formation was higher than that of GDP between 2002 and 2010. The production efficiency of iron and steel smelting and processing industry decreased, and the iron ore consumption coefficient increased, resulting in a sharp increase in iron ore consumption intensity. Therefore, the main contradiction to be solved in the iron and steel smelting and processing industry is to eliminate the excess low-end production capacity and promote the upgrading of the product structure, reduce the iron ore consumption intensity of the whole economy, and achieve the purpose of healthy and stable development of the industry.
