中国の全国炭素排出権取引市場の拡大に伴い、経済全体の炭素二重管理制度と部門別の炭素市場キャップ設定の整合的な協調メカニズムを提案。ボトムアップの省別分解モデルとトップダウンの全国市場キャップ配分モデルを定量的に比較し、省別の炭素予算制約や市場非対象部門の配分、予備放出メカニズムなどを明示的に定式化。シナリオ評価により、ボトムアップモデルは地域のショック吸収力が高く、トップダウンモデルはキャップの透明性が高いことを示した。第15次五カ年計画期間の制度設計に定量的根拠を提供。

This paper develops a quantitative framework to coordinate China's carbon dual control targets with sectoral carbon market cap setting as the ETS expands. It compares bottom-up provincial decomposition and top-down national cap allocation models, incorporating provincial carbon budgets, reserve mechanisms, and allowance shortages. Simulations show the bottom-up model offers stronger local shock absorption, while the top-down model enhances cap transparency. Results inform policy design for the 15th Five-Year Plan.

日本のGX文脈において
中国の炭素市場制度設計に関する研究であり、日本のGX実務に直接適用するものではないが、炭素市場と規制目標の整合性を定量的に評価する手法は、日本のGXリーグやカーボンプライシング導入検討に示唆を与える。特に、省別・部門別の配分と市場メカニズムの協調は、日本の地域別・業種別の排出削減目標設定に参考になる。
In the global GX context
This paper contributes to global carbon pricing scholarship by providing a quantitative framework for coordinating economy-wide emission targets with carbon market caps. It offers insights for countries designing or expanding ETS, such as the EU, and highlights trade-offs between flexibility and transparency. The modeling approach can inform international best practices for carbon market governance.

📄 Abstract（原文）
The expansion of China’s national carbon emissions trading market requires a consistent coordination mechanism between economy-wide carbon dual control targets and sectoral carbon market cap setting. This paper develops a quantitative coordination framework to compare two institutional pathways: a bottom-up provincial decomposition model and a top-down national market cap allocation model. Different from descriptive policy analysis, the proposed framework explicitly formulates provincial carbon budget constraints, market-covered and non-market sector allocation decisions, reserve release mechanisms, and demand-shock-induced allowance shortages. A scenario-based evaluation model is further established to assess total emission cap rigidity, carbon price volatility, reserve utilization, and non-market sector adjustment incentives. Numerical simulations based on heterogeneous provincial emission structures show that the bottom-up model provides stronger local shock absorption capability by allowing intra-provincial reallocation between market-covered and non-market sectors, while the top-down model improves cap transparency but transmits localized allowance shortages more directly into the national carbon market. Sensitivity analysis further indicates that the relative performance of the two models depends on reserve size, provincial non-market abatement flexibility, and the elasticity of carbon prices to allowance shortages. The results provide a quantitative basis for designing coordinated carbon dual control and carbon market cap mechanisms during the 15th Five-Year Plan period.
