| 摘 要： | 考虑到矿山企业经济运行情况主要由成本利润率、工业净产值、矿山资源回收率以及工业产品销售率等因素决定,利用灰色聚类理论对矿山企业历年经济运行情况进行了定权聚类分析。根据聚类分析结果,由经济运行情况较差的年份构成灾变序列,利用灾变式GM(1,1)模型对经济运行情况较差的年份进行了预测,为矿山企业提前应对,减少经济损失提供了依据。

| Abstract: | Considering that the economic performance of mining enterprises depend on cost-profit ratio,net value of industrial output,recovery rate of mineral resources and sales ratio of industrial products,grey clustering theory was applied to the fixed weight clustering analysis of the mining enterprises'economic performance over the years.According to the results of clustering analysis,a catastrophic time sequence was established with the years of poor economic performance,and catastrophe GM(1,1) model was applied... |
