Outline of Final Research Achievements

The research findings are as follows:①investors are aware of the investment risks associated with U.S. companies that insufficiently address environmental issues with high financial materiality. ②short-term stock returns in response to ESG-related events exhibit statistically significant reactions if the events attract high social attention, even if their financial materiality is low. ③the readability scores of ESG disclosure information evaluated within context indicate a trend where heightened attention to ESG lowers the quality of information disclosure. ④the possibility that some companies are actively engaging in environmental investments despite the low correlation with financial performance and high investment costs. ⑤tendency for differences in community attitudes towards sustainability to influence corporate resource allocation.

Academic Significance and Societal Importance of the Research Achievements

本研究の学術的貢献は以下の3点である。1点目はESG投資において投資家の行動がファンダメンタルズ以外の要因に左右されること、その背後に情報の非対称性がある可能性を示した点である。2点目は開示情報の可読性評価に新たな手法を導入し、開示情報の質が情報の非対称性にもたらす影響や情報の質とESGへの社会的な熱狂の関係を検証した点である。3点目は一部の企業のCSR活動の非効率性を数値化し、その背景にステークホルダーの圧力があることを示した点である。ESG投資は注目を集める一方でグリーンウォッシングを始めとする課題も指摘されている。その中で、ESG投資に伴う課題を検証した本研究は社会的意義があると考える。
