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.
Aiming at the situation that there are many influencing factors in the mining enterprise economy and the complexity is relatively high, the mathematical model of the mining enterprise economy is established by using the multi-level nested gray relational analysis method. The absolute gray relation degree, the relative gray relation degree and the comprehensive gray relation degree are adopted The degree index has analyzed the economic factors that affect the mining enterprises and got the main factors and secondary factors that affect the economic growth of the mining enterprises, which provides a reference for the mining enterprises to make investment decisions in the next step.
