摘要

Since 2020, China has adopted a series of policies to create a secure and stable iron ore resource supply chain, such as gradually achieving domestic substitution of iron ore and actively promoting the reuse of scrap steel resources. Based on the material flow data of world and domestic iron resources from 1992 to 2020 and the method of life cycle evaluation, this paper analyzes the economic and environmental impacts of China's response policies to today's world iron ore trade situation, and concludes that China will bear an economic loss of about USD 236.2 billion when the domestic substitution rate of imported iron ore is 45% and the adjustment factor k=10%; with the relevant If the utilization rate of steel scrap is increased to 30%, China will bear an additional 2.3 billion tons of carbon emissions, while the relevant technology level remains unchanged.
