この研究は、中国の水産物輸出に対するEUと英国の国境炭素措置として、炭素サーチャージと低炭素認証を比較。再帰動学CGEモデルを用いて10年間の影響を評価し、認証制度が市場シェアを維持しつつ排出削減を促進することを示した。特に国内のグリーンファイナンスや税制優遇と組み合わせることで効果が高まる。
English
This study compares carbon surcharges and low-carbon certification as EU/UK border measures for China's seafood exports using a recursive dynamic CGE model over 10 years. It finds that certification, especially when paired with domestic green finance or tax offsets, preserves market share better while accelerating adoption of cleaner power and refrigerants compared to uniform surcharges.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の水産物輸出や食品加工業界にも示唆がある。国境炭素措置の設計次第で輸出競争力が左右される点は、EUとの貿易が多い日本企業にとって注目すべき。ただし中国・EU間の分析であり、日本への直接適用には調整が必要。
In the global GX context
This paper provides empirical evidence on how different border carbon adjustment designs affect trade flows and decarbonization in a specific sector. It contributes to the global debate on CBAM design and the role of certification schemes, relevant for ISSB and transition finance discussions.
👥 読者別の含意
🔬研究者:Offers a comparative dynamic assessment of two carbon border instruments using CGE modeling, useful for trade-climate policy research.
🏢実務担当者:Provides insights for seafood exporters on how certification and carbon surcharges could impact market access and costs.
🏛政策担当者:Informs the design of future CBAM-like policies that consider product-level certification to balance emission reductions and trade competitiveness.
📄 Abstract（原文）
This study compares two policy instruments for decarbonizing China’s seafood exports to the EU and UK over 10 years using a recursive dynamic computable general equilibrium model. One instrument applies tariff-like carbon surcharges on embedded emissions at the border. The other recognises certified low-carbon production through tiered rate reductions or exemptions. The model constructs product-level carbon cost wedges for processing electricity, aluminium packaging, and cold-chain operations, then transmits them to border prices through pass-through and to import volumes through Armington demand. These mechanisms operate inside a dynamic setting with capital accumulation, learning, and technology adoption. We evaluate processed tuna, shrimp, whitefish, and fresh tilapia to reflect differences in energy use, packaging intensity, and cold-chain reliance. Results show that certification, especially when paired with targeted domestic green finance or tax offsets, speeds adoption of cleaner power and refrigerants and preserves market share better than uniform surcharges. Effects differ between coastal and inland production hubs, supporting location-specific policy bundles. Sensitivity analysis varies carbon prices, adoption speeds, and certification coverage within stated parameter ranges. We report trade, export revenue, emissions, investment, and welfare outcomes and identify product and channel drivers of exposure.
