2017年(nian)粗鋼(gang)產量(liang)(liang)8.3億(yi)噸(dun)(dun)，同(tong)比增(zeng)加2336萬(wan)噸(dun)(dun)，增(zeng)幅(fu)2.9%。共(gong)消耗(hao)廢(fei)(fei)鋼(gang)鐵(tie)1.48億(yi)噸(dun)(dun)，同(tong)比增(zeng)加5781萬(wan)噸(dun)(dun)，增(zeng)幅(fu)為64.2%。2017年(nian)，受取締'地條鋼(gang)'的影響(xiang)，廢(fei)(fei)鋼(gang)鐵(tie)資源量(liang)(liang)不(bu)斷攀升，導致廢(fei)(fei)鋼(gang)鐵(tie)價(jia)格持續下(xia)跌，廢(fei)(fei)鋼(gang)鐵(tie)替代鐵(tie)礦(kuang)石成本優勢逐漸顯現(xian)，鋼(gang)鐵(tie)企業(ye)開始加大廢(fei)(fei)鋼(gang)鐵(tie)的使用量(liang)(liang)。個人認為，充(chong)分利用國外礦(kuang)產資源，本身是(shi)件好(hao)事，但好(hao)事一定要做好(hao)，也就是(shi)要講代價(jia)，或(huo)者(zhe)說是(shi)經濟上合理(li)，而不(bu)能(neng)不(bu)講代價(jia)。盡管(guan)中(zhong)國銅礦(kuang)資源短(duan)缺。
