本研究以臺灣上市櫃公司為樣本為研究對象，探討董事會結構與企業負面ESG事件之間的關聯性。研究主要分析董事會規模、女性董事比例、獨立董事比例以及是否設立永續委員會等四項公司治理指標，對企業負面ESG事件強度與發生次數的影響。透過臺灣經濟新報(TEJ)資料庫收集相關數據，並使用多元迴歸分析、負二項迴歸模型、傾向分數配對法與順序羅吉斯迴歸模型進行實證檢驗。
研究結果顯示，女性與獨立董事比例越高的公司，其負面ESG事件強度與發生次數顯著較低，顯現其在提升公司治理效果方面具正向影響。而永續委員會設立則未與負面ESG事件呈顯著關聯。然而，董事會規模越大反而與較高的ESG事件強度及發生次數呈現正相關，顯示大型董事會未必具備較佳的風險控管能力。
本研究補足過往文獻在董事會結構與ESG風險管理方面之缺口，提供企業與監管機關在推動永續治理制度設計上的政策參考。實證結果可作為企業優化董事會結構以降低ESG風險之依據，亦能協助金管會等監理機構評估現行董事會組成規範是否具實質效果。

This study examines the association between board structure and negative corporate ESG events in Taiwan-listed companies. It analyzes the impact of four governance indicators—board size, proportion of female directors, proportion of independent directors, and the presence of a sustainability committee—on ESG event intensity and frequency. Data were collected from the Taiwan Economic Journal (TEJ), and empirical tests were conducted using multiple regression, negative binomial regression model, propensity score matching, and ordinal logistic regression model.
Results show that a higher proportion of female and independent directors is linked to significantly fewer and less severe negative ESG events, indicating better governance effectiveness. In contrast, larger boards are associated with more ESG risks, while the presence of a sustainability committee shows no significant effect.
This research contributes to the corporate governance literature by providing empirical evidence from an emerging market, offering insights for both corporate decision-makers and regulators in refining governance frameworks.
