本研究は、2006〜2016年の87カ国のパネルデータと空間計量モデルを用いて、ICT開発がCO2排出に与える影響を分析。国内効果に加え、空間的波及効果を分離し、ICT開発が短期的にCO2排出を増加させ、短期的・長期的に正の空間的波及効果を持つことを示した。貿易開放度が波及効果を緩和することも明らかにし、SDG9とSDG13の政策連携の必要性を強調している。
English
This study analyzes the impact of ICT development on CO2 emissions using panel data from 87 countries (2006-2016) and spatial econometric models. It separates domestic effects from spatial spillovers, finding that ICT development increases emissions in the short run and generates positive spillovers in both the short and long run. Trade openness moderates these spillovers, highlighting the need for international cooperation and policy coordination between digital expansion (SDG9) and climate action (SDG13).

📄 Abstract（原文）
ABSTRACT Information and Communication Technologies (ICT) are often viewed as drivers of innovation, connectivity, and sustainable development. However, their environmental consequences remain unclear when cross‐country spatial links are ignored. This study examines how ICT development affects CO2 emissions in 87 countries from 2006 to 2016 using a balanced panel and spatial econometric models. The analysis separates domestic effects from spillover effects on spatially connected economies. The results show that ICT development increases CO2 emissions directly in the short run and generates positive spatial spillovers in both the short and long run. This suggests that the carbon footprint of digitalization is not limited to domestic emissions. We also find that trade openness reduces the spatial spillovers associated with ICT development, indicating that international integration can help moderate the cross‐border environmental burden of digital expansion. These findings remain robust when alternative ICT indicators and alternative spatial weight matrices are used. The results contribute to the sustainable development debate by showing that digital infrastructure policies linked to SDG 9 should be coordinated with climate action under SDG 13. Since ICT‐related emissions can spill across countries, sustainable digital transformation also requires international cooperation and closer coordination between digital expansion and climate policy.
