本研究は、2000〜2014年の世界産業連関データを用いて、デジタル化が部門別のエネルギー構造転換に与える影響を実証分析した。デジタル化は化石燃料シェアと総エネルギー消費を低下させる一方、非化石エネルギー種別や部門、発展段階によって効果が異なる。エネルギー効率改善やGVCポジション向上が経路として確認され、途上国では構造調整が弱い。
English
Using WIOD data for 2000-2014, this study empirically examines how digital empowerment affects sectoral energy-structure transition. Digitalization is associated with lower fossil-fuel shares and total energy consumption, with effects varying by energy type, sector, and development stage. Channels include improved energy efficiency and GVC positioning, with weaker effects in developing economies.

📄 Abstract（原文）
Digital empowerment has become deeply embedded in global production networks, yet its implications for sectoral energy systems remain insufficiently understood. This study investigates whether digital empowerment is associated with sectoral energy-structure transition and through which channels. Using matched World Input–Output Database accounts for 2000–2014 and applying the Hypothetical Extraction Method (HEM), we measure digital empowerment at the country–sector level and examine its association with sectoral energy-use outcomes. The estimates indicate that digital empowerment is associated with a lower fossil-fuel share and lower total sectoral energy consumption in the full sample, although the associations differ across non-fossil energy categories, sectors, and development stages. Additional channel-based tests show that digital empowerment is associated with lower energy intensity, improved global value-chain positioning, and higher export technological sophistication. Both domestic and foreign digital inputs contribute to this relationship, and manufacturing sectors show a clearer association with lower total energy consumption than service sectors. Developing economies exhibit weaker compositional adjustment than developed economies. These findings provide empirical evidence for integrating digitalization into energy transition strategies and offer practical pathways for aligning digital economic development with sustainable energy objectives.
