中国の炭素排出権取引政策を準自然実験とし、2010〜2024年のA株上場企業パネルデータに多期間DIDを適用。政策が産業内のグリーン技術革新スピルオーバーを有意に促進し、知識拡散と模範効果、競争圧力を通じて技術共有を促すことを示す。知的財産保護の制度環境が正に調整し、ハイテク企業や会長・CEO分離企業で効果が顕著。
English
Using China's carbon emission trading policy as a quasi-natural experiment and a multi-period DID on A-share listed firms (2010-2024), this study finds the policy significantly promotes within-industry green innovation spillovers. Mechanisms include knowledge diffusion, demonstration effects, and competitive pressure, with stronger IPR protection amplifying spillover efficiency. Effects are more pronounced in high-tech firms and those separating chairman and CEO roles.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
中国ETSの産業波及効果を実証した研究で、日本ではGX-ETSやカーボンプライシング設計、SSBJ開示と連動する政策評価の参考になる。技術スピルオーバーと知財保護の相互作用は、日本の産業政策・イノベーション政策の議論に示唆を与える。
In the global GX context
Adds empirical evidence on how carbon pricing drives industry-wide green innovation diffusion, relevant to global debates on ETS design, transition finance, and the innovation channel of climate policy. The IPR-protection moderator offers a governance angle for ISSB/TCFD-aligned disclosure and policy design beyond the EU ETS literature.

📄 Abstract（原文）
The transition of corporate green technological innovation from individual breakthroughs to industry-wide spillovers is a central objective of the carbon emission trading policy in facilitating comprehensive industrial green upgrading and serves as a critical metric for evaluating its systemic effectiveness. Treating the carbon emission trading policy as a quasi-natural experiment, this paper utilizes panel data of Chinese A-share listed companies on the Shanghai and Shenzhen stock exchanges from 2010 to 2024. Employing a multi-period difference-in-differences (DID) approach, the study investigates the impact and underlying mechanisms of the policy on green technological innovation spillovers from an industry-level perspective. The findings reveal the following: (1) The carbon emission trading policy significantly promotes the diffusion of green technological innovation within industries, generating a robust positive technical spillover effect. (2) Mechanism analysis indicates that the policy enhances knowledge diffusion capacity and the demonstration effect within the industry, guiding enterprises toward technology sharing and synergistic innovation under competitive pressure. Moreover, a favorable institutional environment for intellectual property rights (IPR) protection positively moderates and strengthens the policy’s spillover efficiency. (3) Heterogeneity analysis demonstrates that high-tech enterprises are more sensitive to the carbon emission trading policy than ordinary firms. In terms of internal governance, the policy’s effect on augmenting innovation spillovers is more pronounced in firms characterized by the separation of the chairman and CEO roles. Consequently, it is suggested that while refining the design of carbon emission trading policies, policymakers should strengthen IPR protection and optimize corporate governance structures to establish an efficient transmission mechanism for green technology, thereby achieving a holistic low-carbon transition for the industry.
