ESRS義務化前の移行期において、ポーランド企業100社の報告書を6段階尺度で分析し、マテリアリティ評価（MA）開示の深度と決定要因を検証した。ステークホルダー・エンゲージメント、早期ESRS採用、外部保証が開示深度と正に相関する一方、企業規模・セクター・ESG指数加入は有意でなかった。MA開示は構造的属性よりも規範的圧力とシグナリング動機に主導されることを示す。

English

Analyzing 100 Polish company reports on a six-point scale, this study examines the depth and determinants of Materiality Assessment (MA) disclosure during the transitional period before mandatory ESRS. Stakeholder engagement, early ESRS adoption, and external assurance are positively associated with disclosure depth, while firm size, sector, and ESG index membership are not significant. MA disclosure appears driven by normative pressures and signalling rather than structural firm attributes.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

SSBJ基準の導入を控える日本企業にとって、ESRS移行期のマテリアリティ開示の実態と、早期基準採用・外部保証が開示品質を高めるという知見は、有報・統合報告書での対応準備に直接示唆を与える。規制予測が自発的開示を促すメカニズムは、日本でのSSBJ対応戦略にも応用可能。

In the global GX context

As ESRS becomes the EU benchmark alongside ISSB and CSRD, this study offers rare empirical evidence on how regulatory anticipation shapes voluntary materiality disclosure. It informs global debates on double materiality implementation and the signalling value of early standard adoption, relevant to jurisdictions like Japan (SSBJ) and the US preparing similar regimes.

📄 Abstract（原文）

Purpose: The aim of this study is to determine how companies adjust their disclosures on Materiality Assessment (MA) in response to anticipated regulation during the transitional period preceding the mandatory implementation of the European Sustainability Reporting Standards (ESRS).Methodology/approach: The analysis is based on 100 reports published by Polish companies. Using a six-point disclosure scale, we assess the depth of MA disclosures. OLS regression identifies determinants of disclosure quality. The study draws on institutional and signalling theory.Findings: MA disclosure during the transitional period exhibits substantial heterogeneity. While some firms provide comprehensive, methodologically grounded materiality analyses, many limit disclosures to general statements. Stakeholder engagement, recognised reporting frameworks – especially early ESRS adoption – and external assurance are positively associated with disclosure depth. Firm size, sector affiliation, and ESG index membership are not statistically significantly associated with the level of MA disclosures, whereas financial leverage shows a weak negative association with MA disclosures. The results suggest that the MA-related disclosures are driven primarily by normative pressures and signalling incentives rather than structural firm attributes.Originality/value: The study demonstrates how regulatory anticipation influences voluntary sustainability disclosures. It highlights the role of early ESRS adoption as a signal of organisational preparedness.Practical implications: The findings suggest that firms can enhance MA credibility during regulatory transitions by strengthening stakeholder engagement, adopting recognised standards early, and securing external assurance.
