| Abstract: | 本研究旨在探討ESG爭議風險是否會對台灣上市公司之財務績效產生影響，並進一步分析三大構面（環境、社會與治理）爭議的異質性效果，以及企業ESG績效是否具有調節能力。研究樣本涵蓋2018年至2024年間台灣非金融業上市公司，資料來源為TEJ資料庫，採用固定效果模型進行實證分析，控制時間與產業固定效果，並將ESG爭議分為高度與中度風險，以更貼近實務風險判斷。
實證結果顯示，企業若涉入ESG爭議事件，無論風險程度高低，皆會對其資產報酬率（ROA）造成顯著負面影響，尤其在高度風險事件下效果更為明顯。進一步拆解構面後發現，治理構面爭議對績效的負面影響最為顯著且穩定，而環境構面則僅高度風險事件具有影響，且ESG績效對該構面具顯著調節效果；社會構面則未呈現顯著關聯。此外，公司規模亦影響ESG爭議風險的衝擊程度，中小型企業面臨爭議時所受財務損害顯著高於大型企業。
本研究補足台灣ESG爭議風險相關實證文獻之不足，並提供企業在風險管理與永續溝通策略上的參考依據，亦有助於投資人更有效辨識潛在風險與企業價值穩定性。
This study investigates whether ESG (Environmental, Social, and Governance) controversy risks affect the financial performance of publicly listed companies in Taiwan. It further examines the heterogeneous effects across the three ESG dimensions and evaluates whether overall ESG performance moderates the impact of controversies. The sample consists of non-financial firms listed in Taiwan from 2018 to 2024, with data obtained from the TEJ database. A fixed effects model is employed, controlling for year and industry fixed effects, and ESG controversy scores are categorized into high- and medium-risk events for practical relevance.
Empirical results indicate that ESG controversies negatively affect firm performance, measured by Return on Assets (ROA), with high-risk events having a more pronounced impact. When broken down by dimension, governance-related controversies consistently exhibit the strongest negative influence on performance. Environmental controversies only affect ROA in high-risk cases, where ESG performance shows a significant moderating effect. In contrast, social controversies have no statistically significant effect. Moreover, firm size plays a critical role: small and medium-sized enterprises suffer greater financial damage from ESG controversies compared to larger firms.
This study contributes to the limited empirical literature on ESG controversy risk in Taiwan and offers practical insights for corporate risk management and sustainability strategy, while also aiding investors in identifying firms with higher ESG-related vulnerability. |
