日本語
中国A株エネルギー企業914社の2020〜2025年データを用い、デジタル変革が炭素パフォーマンスに与える影響を検証。デジタル化はグリーン特許出願と炭素開示確率を有意に高める一方、開示炭素強度への直接効果は選択補正後も有意でなかった。ETS対象企業は政策節目で負の異常リターンを示し、規制エクスポージャーが価格付けされている。
English
Using 914 Chinese A-share energy firms (2020–2025), this study examines how digital transformation shapes carbon performance. Digitalization significantly boosts green-patent applications and carbon-disclosure likelihood, but direct effects on disclosed carbon intensity remain insignificant after selection correction. ETS-covered firms show negative abnormal returns around policy milestones, indicating priced transition-regulatory exposure.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
中国の炭素開示義務化とETS拡大の文脈で、デジタル化が開示・イノベーションに先行効果を持つことを示す。日本企業のSSBJ対応や有報での気候開示高度化、デジタル投資によるScope把握体制構築を検討する際の参照事例となる。
In the global GX context
This paper contributes to global disclosure scholarship by showing that digitalization precedes measurable emission reductions, with disclosure and green innovation as early margins. It informs ISSB/CSRD implementation debates on the sequencing of digital infrastructure, disclosure mandates, and carbon pricing, and highlights investor pricing of ETS exposure.

📄 Abstract(原文)
China’s dual-carbon goals have made understanding how digital transformation shapes corporate carbon performance a policy priority, and the rapid expansion of firm-reported emissions disclosure since 2020 now makes such inquiry feasible at scale. Drawing on CSMAR financial data and CNRDS digital-transformation keyword frequencies for 914 A-share energy firms over 2020–2025, we combine panel fixed-effects models, a placebo-validated triple-difference design, disclosure-choice models with a Heckman selection correction, and event studies of two policy milestones. We find that digital transformation robustly stimulates green-patent applications and significantly raises the likelihood of carbon disclosure in the cross section, identifying green-patenting and disclosure as the two margins on which digitalization is already measurable. The direct association with disclosed carbon intensity remains statistically insignificant in the selection-corrected model and on the directly disclosed subsample, indicating that emission reductions are not yet measurable at the firm level. A sharp but short-lived emission-reduction pulse among digitalized high-carbon firms in 2021 is consistent with but does not confirm a Porter-type mechanism. Investors nonetheless priced transition-regulatory exposure: ETS-covered firms earned significantly negative abnormal returns around both policy milestones. Thus, digitalization in China’s energy sector is already visible in what firms invent and disclose, with measurable emission and valuation effects likely to follow as disclosure mandates and carbon pricing mature.
