中国のサプライチェーン革新・応用パイロット政策を自然実験として、279都市の2005〜2021年パネルデータを用い、供給網デジタル化が都市の大気汚染物質とCO2排出を局地的に7.1〜9.9%削減する一方、隣接地域では4.4%増加することを示した。中規模・非工業都市で効果が高く、大都市や工業集積地では限定的。地域間排出波及を抑えるため、都市間排出権取引や共有型MRV基盤などの統合的施策の必要性を提言している。
English
Using China’s Supply Chain Innovation and Application Pilot Policy as a quasi-natural experiment with a city-year panel of 279 cities (2005–2021), the study finds that supply chain digitalization reduces local urban pollutants and CO2 emissions by 7.1–9.9% but increases them by 4.4% in neighboring jurisdictions. Medium-small and non-industrial cities benefit most. The authors advocate for integrated regional instruments, such as linked emissions trading schemes and shared digital monitoring, reporting, and verification infrastructure, to mitigate spillovers.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではSSBJ開示やサプライチェーン排出量算定が進むが、本稿は供給網デジタル化が排出削減に与える実証的示唆を提供する。地域間スピルオーバーの存在は、広域連携による排出削減政策の設計や、企業のサプライチェーン管理戦略にも示唆を与える。
In the global GX context
For global GX scholarship, this paper offers causal evidence on how digital supply chain policies affect emissions, highlighting local leakage effects that matter for designing effective climate policy under frameworks like the Paris Agreement. The call for linked emissions trading and shared MRV infrastructure resonates with current debates on carbon market integration and disclosure harmonization (e.g., ISSB, global GHG accounting).
👥 読者別の含意
🔬研究者:Provides a rigorous quasi-experimental estimate of supply chain digitalization on emissions, with spillover analysis that informs climate policy evaluation methodology.
🏢実務担当者:Japanese companies with China-based supply chains can anticipate local emission reductions but also potential leakage risks when assessing Scope 3 and regulatory exposure.
🏛政策担当者:Emphasizes the need for regional coordination—linked ETS and shared digital MRV—to prevent emissions spillover from digitalization-driven local gains.
📄 Abstract（原文）
The digital transformation of supply chains presents a promising option to reduce urban pollutants and carbon dioxide emissions. Here, we utilize China’s Supply Chain Innovation and Application Pilot Policy as a quasi-natural experiment. We assess its impact on urban pollutants and carbon dioxide emissions. We compile a city-year panel dataset by merging high-resolution emissions inventories with socioeconomic data across 279 prefecture-level cities from 2005 to 2021. We found that supply chain digitalization reduces urban pollutants and carbon dioxide emissions by 7.1%-9.9% locally; however, these emissions increase by 4.4% in neighboring jurisdictions. Medium-small-sized and non-industrial cities benefit the most from supply chain digitalization, while megacities and entrenched industrial hubs see modest benefits. Our findings show that while digital supply chain innovations can advance urban sustainability, integrated regional instruments, such as linked city-level emissions trading schemes and shared digital monitoring, reporting, and verification infrastructure, are needed to reduce emissions spillover. Supply chain digitalization reduces urban air pollutants and carbon dioxide emissions by up to 9 percent locally but increases them by 4 percent in nearby areas, according to an analysis that uses a quasi-natural experiment and a difference-in-differences method
