本研究は中国のダブル政策パイロット（MSWとETSの同時実施）を対象に、政策連携が炭素排出効率（CEE）に与える影響を検証した。差分の差分法を用い、2000～2022年の283都市のパネルデータを分析した結果、同時実施はCEEを向上させる相乗効果があり、その効果は科学教育への財政支出増加を介して部分的に実現され、第二次産業比率の高い都市で顕著であることを示した。
English
This study examines the synergistic effect of jointly implementing municipal solid waste management (MSW) and emissions trading scheme (ETS) on carbon emission efficiency (CEE) in urban China. Using a difference-in-differences design with panel data for 283 cities from 2000 to 2022, it finds that joint implementation improves CEE, partly through increased fiscal expenditure on science and education, and the effect is stronger in cities with a higher share of secondary industry.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
本論文は中国事例だが、日本においても廃棄物管理と排出権取引の政策連携は、SSBJや地球温暖化対策計画の文脈で重要になりうる。特に、複数政策の相乗効果を実証した点は、日本の自治体や企業が複合的な脱炭素対策を設計する際の示唆となる。
In the global GX context
This paper provides empirical evidence on the complementary effects of regulatory and market-based instruments, relevant for global climate policy design. It advances understanding of policy synergy beyond single-policy evaluations, offering lessons for developing countries and regions implementing coordinated environmental policies, including under the ISSB framework and transition finance.
👥 読者別の含意
🔬研究者:Provides a robust DID analysis of policy synergy, advancing the literature on policy mix evaluation and carbon emission efficiency.
🏢実務担当者:Limited direct applicability, but highlights the importance of coordinating waste management and carbon pricing for urban sustainability strategies.
🏛政策担当者:Offers evidence that combined regulatory and market instruments can yield synergistic effects, useful for designing coordinated environmental policy packages.
📄 Abstract（原文）
When implemented jointly, different policy instruments do not necessarily produce additive effects; they may reinforce one another, but they may also involve trade-offs. Existing studies have largely evaluated the regulatory Municipal Solid Waste Management policy (MSW) and the market-based Emissions Trading Scheme (ETS) separately, leaving limited evidence on whether these two types of policy instruments are complementary or conflicting when implemented within the same city. Focusing on China’s dual policy pilot (DPP), where MSW and ETS are jointly implemented, this study employs a difference-in-differences design with panel data for 283 cities from 2000 to 2022 to identify the effect of joint policy implementation on carbon emission efficiency (CEE) and to examine its underlying mechanisms and conditional heterogeneity. The results show that the combined policy improves CEE and generates a synergistic effect. This effect is partly realized through increased fiscal expenditure on science and education and is more pronounced in cities with a higher share of secondary industry. These findings move beyond single-policy evaluation and provide useful implications for developing countries in Asia and Africa in designing coordinated environmental policy mixes.
