日本語

本研究は、創業者や支配家族の名前を冠した同族企業(eponymous firms)が、評判と正当性の懸念から自主的なESG報告を行う可能性が高いことを、2013年から2021年のイタリアの非公開同族企業2,769社のデータを用いて実証した。希少な姓、メディア露出、好意的な報道などの評判的露出が高い場合に効果が強まり、開示は実質的なESG行動を伴うことを示した。

English

This study examines how reputation linked to family identity affects voluntary ESG disclosure in private family firms, focusing on eponymous firms. Using 2,769 Italian private family firms from 2013 to 2021, it finds that eponymous firms are more likely to publish ESG reports, especially when reputational exposure is high. The disclosure reflects genuine engagement, with lower realized environmental impact.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本では、非公開企業のESG開示は任意であり、SSBJ適用は上場企業中心。しかし、同族企業やオーナー企業がサプライチェーンで開示要請を受けるケースが増えており、評判と正当性の観点から開示行動を理解することは、日本企業の実務にも示唆を与える。

In the global GX context

Globally, this paper contributes to the disclosure literature by showing that reputational incentives, particularly family identity, drive voluntary ESG disclosure in private firms. It complements mandatory disclosure frameworks like ISSB and CSRD by highlighting the role of legitimacy in voluntary reporting, relevant for understanding private firm behavior in global supply chains.

📄 Abstract(原文)

This study examines how reputation linked to family identity affects voluntary ESG disclosure in private family firms, focusing on eponymous firms-those named after their founders or controlling families. Drawing on legitimacy theory, we argue that when family and firm identities are closely aligned, ESG disclosure serves to protect and signal legitimacy to external stakeholders. Using a sample of 2,769 Italian private family firms from 2013 to 2021, we find that eponymous firms are significantly more likely to publish ESG reports. The effect is stronger when reputational exposure is higher, including cases of rarer surnames, greater press visibility, and more positive prior media sentiment. Eponymous firms also report more substantive ESG actions-particularly in social and environmental domains-and exhibit lower realized environmental impact, suggesting that disclosure reflects genuine engagement rather than symbolic reporting. Robustness tests address alternative governance, visibility, reporting standardization, and selection explanations. Overall, the evidence indicates that owner identity, reputation, and legitimacy concerns jointly shape voluntary ESG disclosure and sustainability outcomes in private family firms.
