铜产业链上产品的多种性导致其在流通过程中风险传导的多级性,各种产品作价方式、增值税率的差异等又会影响通过期货市场保值的效果。如矿山原料变成铜产品的流程是:铜矿石→铜精矿→冰铜→粗铜→阳极铜→电解铜→铜产品。而通常所说的“废杂铜”变成铜产品的过程大致是:废电机废电缆等→废杂铜→粗铜→阳极铜→电解铜→铜产品,但这中间还有废杂铜直接到铜产品的更先进的流程。目前普遍的情况是,在这个完整的加工链中,
The variety of products in the copper industry chain leads to multi-level risk transmission in the process of circulation. The method of pricing various products and the difference of the VAT rate will affect the effect of preserving the value through the futures market. Such as mine raw materials into copper products process is: copper ore → copper concentrate → matte → copper → anode copper → electrolytic copper → copper products. The so-called “scrap copper ” into the copper product process is roughly: waste motor scrap cables, etc. → scrap copper → blister copper → anode copper → electrolytic copper → copper products, but there are still miscellaneous intermediate miscellaneous Copper goes directly to the more advanced processes of copper products. The prevailing situation is that in this complete processing chain,
