特恵貿易協定（PTA）が貿易に体化された炭素排出に与える影響を、二国間貿易データと段階的差分の差分法を用いて実証分析。PTA締結は輸出に体化された炭素を削減し、そのメカニズムは生産効率の向上と技術波及であることを示した。また、相手国の発展段階や環境規制の強度が効果に影響することを明らかにした。
English
This study empirically examines how preferential trade agreements (PTAs) affect embodied carbon emissions in trade using bilateral trade data and a staggered difference-in-differences approach. It finds that PTA signing reduces carbon embodied in exports, driven by improved production efficiency and technological spillovers. Heterogeneous effects depend on trading partners' development levels and environmental regulation stringency, offering evidence for designing climate-aligned trade policies.

📄 Abstract（原文）
The pursuit of sustainable development, particularly the mitigation of climate change (SDG 13), necessitates a thorough understanding of the environmental consequences of international trade. The form and pattern of international trade have changed with the rise of preferential trade agreements. The following important question arises: how do preferential trade agreements affect the transfer of trade-embodied carbon emissions? This study establishes a comprehensive bilateral trade database and uses a staggered difference-in-differences model to empirically examine how preferential trade agreements affect embodied carbon emissions. Furthermore, this study explores the underlying mechanisms and investigates heterogeneous effects in diverse contexts. The key findings of this study are as follows. (1) The signing of preferential trade agreements between bilateral trading partners helps reduce the level of carbon embodied in exports. (2) This reduction is achieved by improving production efficiency and facilitating technological spillovers, thereby reducing the carbon footprint associated with export activities. (3) The level of development of bilateral trading countries and the strength of environmental regulations play a role in the heterogeneous impact of preferential trade agreements on embodied carbon emissions. These findings provide critical empirical evidence for designing PTAs that not only facilitate trade but also actively contribute to global climate action and the achievement of broader sustainability objectives.
