中国30省・2011〜2022年のパネルデータを用い、デジタル経済発展がエネルギー効率に与える直接効果・媒介効果・非線形効果をIV推定・媒介分析・閾値回帰で検証した。デジタル化の直接効果は有意に正だが、技術革新と経済成長は競合的媒介、エネルギー消費構造と産業構造は間接的媒介として作用する。閾値分析では低発展段階では正、中間段階では負の効果が示され、市場化が鍵となる解放条件であることが判明した。
English
Using panel data from 30 Chinese provinces (2011–2022), this study examines direct, mediating, and nonlinear effects of digital economy development on energy efficiency via IV estimation, mediation analysis, and threshold regression. Digitalization shows a significantly positive average effect, with technological innovation and economic growth as competitive mediators and energy/industrial structure as indirect-only mediators. A nonlinear pattern emerges: positive at low development levels, negative at intermediate stages, with marketization as the critical unlocking condition.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではGX推進法・第7次エネルギー基本計画のもとでDXと省エネの統合が政策課題となっており、デジタル化の効果が発展段階で非線形になるという知見は、地域別・産業別の省エネ政策設計やSSBJ開示におけるエネルギー効率指標の解釈に示唆を与える。
In the global GX context
As global disclosure frameworks (ISSB, CSRD) increasingly require energy-efficiency and transition-plan metrics, this paper's finding that digitalization's efficiency dividend is stage-contingent and marketization-dependent cautions against treating digital adoption as an automatic decarbonization lever in corporate transition narratives.
👥 読者別の含意
🔬研究者:デジタル化とエネルギー効率の非線形・媒介構造を識別した実証枠組みは、地域別GX政策評価の手法として参考になる。
🏢実務担当者:DX投資を省エネ・GX施策として位置づける際、発展段階や市場環境により効果が逆転しうる点を投資判断・開示に織り込む必要がある。
🏛政策担当者:デジタル化の省エネ効果を最大化するには市場化改革と段階別の差別化政策が不可欠であることを示唆する。
📄 Abstract（原文）
ABSTRACT This paper investigates the direct, mediating, and nonlinear effects of digital economy development on energy efficiency using panel data from 30 Chinese provinces spanning 2011–2022. The empirical strategy integrates instrumental variable estimation, mediation analysis, and threshold regression, complemented by extensive robustness checks. The findings reveal three key results. First, the direct effect of digitalization on energy efficiency is significantly positive, confirming its average contributive role. Second, mediation analysis identifies the following four significant transmission pathways: Technological innovation and economic growth operate as competitive mediators, while energy consumption structure and industrial structure function as indirect‐only mediators. Third, threshold analysis uncovers a distinct nonlinear pattern: digitalization promotes energy efficiency at low development levels but exhibits a negative effect during intermediate stages, with marketization serving as the critical unlocking condition. These findings are validated through comprehensive robustness checks, including varying‐coefficient modeling, spatial spillover analysis, dynamic lag specifications, and COVID‐19 pandemic controls. This study demonstrates that digitalization's energy efficiency dividend is positive on average yet contingent on development stages and regional conditions. Market‐oriented institutional reforms are essential for unlocking this potential, and differentiated policies should be designed according to specific threshold conditions.
