本研究は中国の排出権取引制度（CETS）が企業の大気汚染物質排出に与える影響を検証。1998-2014年の企業・都市データを用いた差分の差分分析により、CETSが排出量を平均11.02%削減し、特に二酸化硫黄（-17.93%）、窒素酸化物（-10.18%）、粉じん（-11.2%）で顕著であることを示した。その効果は技術革新を通じて発現し、大企業や東部地域、低負債比率企業、高汚染産業で強い。
English
This study examines whether China's carbon emissions trading system (CETS) reduces firms' air pollutant emissions. Using firm-level panel data from 1998-2014 and a staggered difference-in-differences design, the authors find that CETS reduces emissions by 11.02% on average, with larger reductions for SO2, NOx, and dust. The effect operates through technological innovation and is stronger for large firms, eastern regions, low-debt firms, and high-polluting industries.

日本のGX文脈において
日本でも2023年から炭素価格付けが本格化しており、排出権取引の副次的効果を示す本知見は、日本のカーボンプライシング制度設計（特にGX実現に向けた政策）に示唆を与える。ただし中国特有の制度・産業構造に依存する部分もあり、直接応用には注意が必要。
In the global GX context
This paper provides causal evidence from the world's largest developing economy that carbon pricing can generate significant co-benefits for local air pollution. The findings are relevant for global climate policy and for developing countries designing emissions trading schemes, reinforcing the case for integrating carbon markets with conventional pollution control.
👥 読者別の含意
🔬研究者:Useful for scholars studying co-benefits of carbon pricing and the mechanisms (technological innovation) through which they operate.
🏢実務担当者:Relevant for corporate sustainability teams in China, but not directly applicable for global practitioners.
🏛政策担当者:Provides empirical support for the design of emissions trading systems, especially in developing economies, highlighting co-benefits beyond carbon reduction.
📄 Abstract（原文）
Market-based instruments (MBIs) play an increasingly important role in environmental governance, yet their broader effects beyond carbon mitigation remain insufficiently understood. This study examines whether China’s carbon emissions trading system (CETS) reduces firms’ air pollutant emissions. We construct a firm-level panel by matching the China Industrial Enterprise Database with the China Industrial Enterprise Pollution Database for 1998–2014 and link these data to city-level information on CETS pilot implementation. Using a staggered difference-in-differences design, together with robustness checks including PSM-DID and placebo tests, we estimate the effect of CETS on firm-level air pollutant emissions. The results show that CETS significantly reduces firms’ air pollutant emissions by 11.02% on average. The reductions are particularly pronounced for sulfur dioxide (−17.93%), nitrogen oxides (−10.18%), and dust (−11.2%). Mechanism analysis indicates that the effect operates primarily through technological innovation, and heterogeneity analysis shows stronger effects among large enterprises, firms in eastern regions, firms with lower debt ratios, and highly polluting industries. These findings extend the understanding of MBIs beyond carbon mitigation by documenting co-benefits for conventional air pollution control in the world’s largest developing economy. The study also provides policy-relevant evidence for the design of emissions trading schemes in other developing economies.
