矿山企业经济的多层次嵌套型灰色关联分析

Multi-layer nested grey incidence analysis to economic of mining enterprise

针对矿山企业经济的影响因素多且比较复杂的情况,利用多层次嵌套型灰色关联分析方法,建立了矿山企业经济数学模型,采用绝对灰色关联度、相对灰色关联度和综合灰色关联度等关联度指标对影响矿山企业的经济因素进行了分析,得出影响矿山企业经济增长的主要因素和次要因素,为矿山企业下一步进行投资决策提供了参考依据.图5,表5,参8.

To the influent faclors of ntining enterprises economic are many and complex, Muhi-layer nested grey incidence analysis method applied to establish a mathematical model, the absolute degree of incidence, relative degree of incidence and synthetic degree of incidence were used to analyze the influent factors of mining enterprise economic, the principal influent factors and secondary influent factors of mining enterprise eeonomic growth are classified, and provide the reference for investment decision. 5figs., 5tabs., 8refs.
