利用灰色关联度模型对江苏省工业增加值与工业用电量、工业贷款额、工业固定资产投资额之间的灰色关联性进行研究。经过求取灰色绝对关联度、灰色相对关联度,进而计算出灰色综合关联度,最终得到工业增加值与工业用电量、工业贷款额、工业固定资产投资额之间的灰色关联性大小,并据此对三种因素进行排序。结果表明,工业贷款额对工业增加值的影响最大,工业用电量、工业固定资产投资额次之。
The gray relational degree model is used to study the gray relation between industrial added value and industrial electricity consumption, industrial loan amount and industrial fixed asset investment in Jiangsu Province. After obtaining the absolute gray relational degree and the gray relative relation degree, the gray comprehensive relation degree is calculated, and the gray relational degree between industrial added value and industrial electricity consumption, industrial loan amount and industrial fixed asset investment is obtained finally. According to the three factors to sort. The results show that the amount of industrial loans has the greatest impact on industrial added value, followed by industrial electricity consumption and industrial fixed asset investment.
