摘　　要：为量度供给侧结构性改革背景下金属矿业产业结构升级效果,基于已有文献,运用产业结构超前系数、Moore结构变化值、产业结构升级高度值构建了反映产业结构升级方向、速率和程度的测算模型,并利用2013—2018年数据测算了供给侧结构性改革前后金属矿业产业结构的升级情况。结果表明:通过升级方向测算,发现改革后的超前系数高于改革前,且冶炼及压延加工业高于采选业;通过升级速率测算,发现改革后黑色金属矿和有色金属矿的产业结构均有了明显提升,且黑色金属矿比有色金属矿升级相对更快些;黑色金属矿和有色金属矿改革后的Moore值均接近于1;黑色金属矿矢量夹角由1.45°扩大到5.35°,有色金属矿矢量夹角由1.32°扩大到4.61°;通过升级程度测算,发现产业结构升级高度值基本呈现逐年递增的趋势,表明黑色金属矿、有色金属矿产业结构均经历了从低级阶段向高级阶段演变的过程。在测算结果的基础上,提出了相关政策建议。In order to measure the upgrading effect of metal mining industry structure under the background of the structural reform of supply-side,based on the existing literature,the advanced coefficient of industrial structure,Moore structure change value and industrial structure upgrade height value are used to construct a calculation model which reflects the direction,rate and degree of industrial structure upgrade.The data from 2013 to 2018 are used to calculate the upgrading of metal mining industry structure before and after the reform.The results show that through the measurement of upgrade direction,it is found that the leading coefficient of supply side is higher than before the reform,and the smelting and calendaring industry is higher than the mining and selecting industry.Through the calculation of upgrading rate,it is found that the industrial structure of ferrous mine and non-ferrous metal mine has been improved obviously after the reform,and ferrous mine is upgraded relatively faster than non-ferrous metal mine.After the reform of ferrous and non-ferrous metal,the Moore value is close to one;the vector angle of ferrous ore increases from 1.45°to 5.35°,and the vector angle of non-ferrous metal ore increases from 1.32°to 4.61°.Through the measurement of the upgrading degree,it is found that the upgrading height of the industrial structure basically presents the trend of increasing year by year,which indicates that the industrial structure of ferrous and non-ferrous metal has undergone the process of evolution from the lower stage to the higher stage.According to the result of calculation,some policy suggestions are put forward.
