本研究は、鉄鋼業の低炭素移行を分析する統合モデル（IIAM）を開発し、技術選択とマクロ経済シミュレーションを組み合わせた。スクラップ利用率向上と水素冶金が有望であるが、プロセス改革はコスト増を伴う。短期的には既存設備の改造、長期的には革新的技術への移行が推奨される。
English
This study develops an integrated iron and steel assessment model (IIAM) combining technology choice and macroeconomic simulation to analyze low-carbon transition pathways for China's steel industry. Increasing scrap utilization and hydrogen-based metallurgy are promising, while process reformation pathways offer greater benefits but with higher costs. Short-term retrofitting and long-term innovation are recommended.

📄 Abstract（原文）
Abstract As a hard-to-abate sector and an industrial backbone, the iron and steel industry involves a low-carbon transition that is crucial for China to achieve green growth and emission reduction targets. This study developed an innovative integrated iron&steel assessment model (IIAM), combining technology-choice modules with bottom-up technological analysis and top-down macroeconomic simulation to conduct low-carbon transition pathway analysis. In comparison with a carbon-reduction scenario in which reducing CO2 emissions relies on scaling down production and constrained economic growth, the planned national iron and steel industry development pathway has advantages in technological progress and structural adjustments. To realize potentially greater synergistic energy–environmental–economic benefits, two sets of substitutive low-carbon transition pathways are proposed on the basis of forward-looking technologies and production processes reformation. Among key technology deployment pathways, increasing scrap utilization is the preferred option, and hydrogen metallurgy excels in cleaning the energy mix. Production process reformation pathways can further unlock the potential for carbon mitigation, air-pollution control, resource use, and economic growth, yet they involve cost increases. The short-term strategy should prioritize existing long-process retrofitting, whereas the long-term transition should focus on scrap utilization, hydrogen-based metallurgy, and more breakthrough technological innovations.
