摘要
运用协整理论和灰色系统对中国1979-2008年的粗钢消费量和GDP进行分析,并对中国2009-2020年粗钢需求量进行了预测和修正,得到中国2015年粗钢需求量在6.4-7.3亿吨之间,2020年在8.2-8.8亿吨之间的结论.
Using the theory of cointegration and grey system,steel consumption and GDP of China from 1979 to 2008 were analyzed.The paper also forecasts and corrects steel demand of China from 2009 to 2020.The conclusion is that steel demand of China will be 64000-73000 million tons in 2015 and 82000-88000 million tons in 2020.
