中国の鉄鋼セクターは国家・世界の気候目標達成に重要だが、石炭ベースの工程や地域格差が障壁となっている。本研究では、政策シグナルと企業の投資判断を結びつけるエージェントベースモデルを開発。統合的な政策と技術進歩の組み合わせが、高炉の早期廃止と急激なCO2削減を実現することを示した。
English
China's steel sector is critical for climate goals but hampered by coal-based processes and regional disparities. This study develops an agent-based model linking policy signals (carbon caps, pollution standards) with firm-level investment decisions. Results show that only the integrated policy-plus-technology pathway eliminates blast furnaces before midcentury, achieving the steepest CO2 reductions (90-95% by 2060). Synchronizing stringent climate policy with rapid technology cost declines is essential for a carbon-neutral trajectory.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本鉄鋼業界にとっても、中国の脱炭素経路分析はベンチマークとなる。政策と技術の同期の重要性は、日本のGX政策（例えばグリーンイノベーション基金やカーボンプライシング）にも示唆を与える。
In the global GX context
This paper offers a novel agent-based modeling framework for steel decarbonization, highlighting the critical role of policy-technology synchronization—a key insight for global climate governance and transition finance. The Chinese case provides benchmarks for other major steel-producing nations, including Japan, EU, and the US.

📄 Abstract（原文）
China’s steel sector is pivotal to national and global climate goals, yet decarbonization is constrained by entrenched coal-based processes and regional disparities. Top–down and bottom–up models often neglect firm-level heterogeneity and behavioral dynamics. Here, we develop an agent-based model linking policy signals—carbon caps, pollution standards, and resource limits—with firm-level investment decisions. We evaluate four scenarios combining current and strengthened climate and air targets with neutral or accelerated technology progress. All scenarios achieve deep CO 2 reductions (90 to 95% by 2060), but only the integrated policy-plus- technology pathway eliminates blast furnaces before midcentury, achieving the steepest declines. Policy- or technology-only pathways entail trade-offs, including lock-in to carbon capture and storage or delayed reductions. Our results show that synchronizing stringent climate policy with rapid technology cost declines is essential to steer China’s steel industry toward a carbon-neutral trajectory.
