中国の排出量取引パイロットが企業のグリーン特許に与える影響を、デジタル変革能力の調整効果に着目して分析。31,048社年データを用いた差の差分析により、平均効果は非有意だが、デジタル能力が高い企業では特許が4.6%増加することを示した。ポーター仮説を組織能力の視点から拡張する。
English
This study examines how China's carbon trading pilots affect green innovation, focusing on the moderating role of digital transformation. Using a DID design on 31,048 firm-year observations, it finds no average effect but a significant 4.6% increase in green invention patents for firms with high digital capability, extending the Porter hypothesis to organizational capabilities.

📄 Abstract（原文）
Whether China’s carbon trading pilots stimulate firm-level innovation remains contested. This study investigates the conditional effect of carbon pricing on green invention patents, moderated by firms’ digital transformation capability. Using an unbalanced panel of 31,048 firm-year observations from A-share listed companies (2011–2022) and a two-way fixed-effects difference-in-differences estimator, we find no significant unconditional average treatment effect, consistent with attenuated price signals in China’s pilots. However, digital capability substantially amplifies the innovation response: a one-standard-deviation increase in within-year digital capability is associated with a 4.6% rise in expected green invention patents among treated firms. The moderating effect is exclusive to examination-intensive invention patents rather than utility model registrations, consistent with a strong-form Porter mechanism. Sub-dimension analysis identifies strategic leadership and digital achievement as the operative channels. The results are robust to alternative estimators, cohort decomposition, and sample restrictions. Together, the findings reframe digital transformation as a policy-contingent complementary asset and extend the Porter hypothesis to an organizational-capabilities dimension.
