利用1999～2009年我国资源开采业的产值数据,采用灰色关联分析,确定了资源开采业优先发展的行业为有色金属行业,同时构建了6个子产业的GM(11,)模型,并对模型进行了后验比和小概率误差的检验,发现除了其他采矿业模型不成立外,其他5个模型成立。最后,利用预测模型对资源开采业各行业未来五a的产值进行了灰色预测。
By using the gray relational analysis, this paper determined that the priority industry of resource exploitation industry was non-ferrous metal industry, and built the GM (11,) model of six sub-industries at the same time, and carried out the model The test of the posteriori ratio and the small probability error found that the other five models were established except for the other mining models. Finally, the prediction model is used to forecast the output value of each industry in the next five years in resource exploitation industry.
