日本語

中国の上場企業3500社超の特許データを用い、ESG情報開示が環境イノベーション（グリーンパテント）に与える影響を構造モデルで実証。開示企業は非開示企業に比べ、グリーン特許出願が15.8%、登録が21.4%増加。国有企業や大規模・高レバレッジ企業で効果が強く、外部モニタリングの強化や低汚染セクターで顕著。ESG開示が企業の環境イノベーションを促進することを示す。

English

Using patent data from over 3,500 Chinese listed firms, this study develops a structural model to show that ESG disclosure significantly boosts green innovation: disclosers see a 15.8% increase in green patent applications and 21.4% in authorizations. Effects are stronger for SOEs, larger firms, and those with higher leverage or overinvestment, and are amplified by external monitoring and industry norms. The evidence underscores ESG disclosure as a key driver of corporate environmental innovation.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本ではSSBJ開示義務化が迫る中、ESG情報開示が実体経済（イノベーション）に与える効果を示す本研究成果は、開示の便益を裏付けるエビデンスとして有用。日本企業の開示対応や投資家対話において、開示が企業価値向上につながる論拠となる。

In the global GX context

This paper provides causal evidence that ESG disclosure spurs green innovation, directly relevant to global disclosure regimes like ISSB and CSRD. It strengthens the business case for mandatory disclosure, showing tangible innovation benefits beyond compliance. The structural model offers a methodological template for evaluating disclosure impacts in other jurisdictions.

📄 Abstract（原文）

Using Patent Application Data from the State Intellectual Property Office of China, we examine the relationship between ESG information disclosure and firms' environmental innovation, using more than 3500 listed firms. Methodologically, we develop a micro‐founded structural model, which maps directly to relevant empirical regressions. The model supports the validity of our identification and design. We find that firms which disclose ESG information average a 15.8% increase in green patent applications and a 21.4% increase in green patent authorizations as compared to non‐disclosers. The effects are stronger for state‐owned enterprises and for larger, more leveraged, and overinvesting firms. The effects are more pronounced when external monitoring is stronger, with higher analyst attention, and in sectors with historically lower pollution, consistent with capital‐market disciplinary pressures and industry norms. In conclusion, the evidence strongly suggests that ESG disclosure is a substantial driver of corporate environmental innovation, which has relevant implications for regulators and financial decision‐makers.
