摘　　要：2021年我国铁矿石对外依存度降至76.2%,连续第四年降低,也是自2015年以来首次降至80%以下。这与近几年国内铁矿石产量持续增长息息相关。国内铁矿石原矿产量连续三年增长,与粗钢产量的差距得以修复。从对我国生铁产量铁元素贡献来看,国产矿的贡献占比连续四年上升,从2017年的9.2%上升至2021年的23.2%。2021年,我国黑色金属矿采选业固定资产投资额增长26.9%,增速创近十年新高,与钢铁业投资增速的匹配度获得提升。China's dependence on imported iron ore dropped to 76.2%in 2021,declined in the fourth consecutive year,and fell below 80%for the first time since 2015.This was closely related to the continuous growth of domestic iron ore production in recent years.The gap between domestic raw iron ore output and that of crude steel narrowed with the former increased for three consecutive years.Seeing from the contribution to iron element of China's pig iron production,the contribution proportion of domestic iron ore grew for four consecutive years,from 9.2%in 2017 to 23.2%in 2021.In 2021,the fixed asset investment in China's ferrous metal mining and dressing industry went up by 26.9%,recording a new high in the past ten years,and the suitability with the growth rate of investment in steel industry improved.
