| Abstract: | 本研究旨在探討企業ESG評級對財務績效之影響，並進一步檢視產業異質
性是否構成調節因素。隨著永續資訊揭露制度趨於成熟，ESG評級逐漸成為投資決策與企業風險評估之重要依據，惟其對財務績效之影響可能因資訊結構與產業條件而異。為探討此一議題，本文以臺灣上市櫃製造業與服務業企業為研究對象，選取TEJ資料庫中之TESG分數與事件雷達轉換計分，分別代表企業永續表現之整體型與事件型指標，並以ROA與Tobin's Q衡量財務績效，進行多元迴歸與產業分組分析。
實證結果顯示，TESG分數對ROA與Tobin's Q皆具穩定且顯著之正向預
測效果，顯示其具有跨產業解釋力與應用性。相對地，事件雷達轉換計分僅對ROA具顯著解釋力，且預測效果主要集中於服務業，顯示事件型ESG風險資訊對營運績效之影響具產業差異。進一步的交互作用與子樣本分析亦驗證，產業結構對事件型資訊與財務績效間之關係具有調節效果，驗證服務業樣本對ESG事件風險之財務反應較為敏感。
整體而言，ESG資訊具備財務預測功能，惟其效果會因資訊類別與產業結
構而異。本研究結果除補充ESG實證文獻中對資訊異質性與產業調節機制之理解，亦可為企業永續溝通、投資評估與評級制度設計提供實務參考。
This study investigates the impact of corporate ESG ratings on financial performance, with a particular focus on whether industry heterogeneity serves as a moderating factor. As sustainability disclosure frameworks become increasingly
institutionalized, ESG ratings have emerged as a critical reference for investment decisions and corporate risk assessments. However, their effect on financial outcomes
may vary depending on the nature of ESG information and industry context. To examine this issue, this study selects listed manufacturing and service firms in Taiwan as the research sample and adopts two indicators from the TEJ database—TESG scores and Event Radar Transformed Scores—representing, respectively, the overall type and event-type dimensions of corporate ESG performance. ROA and Tobin’s Q
are employed as measures of financial performance, with empirical analyses conducted through multiple regression and industry subgroup comparisons.
The results reveal that TESG scores exhibit a stable and significantly positive predictive effect on both ROA and Tobin’s Q, indicating cross-industry explanatory power and applicability. In contrast, the Event Radar Transformed Score is only significantly associated with ROA, with its predictive effect concentrated primarily in the service sector, suggesting that event-type ESG risk information influences operating performance in an industry-specific manner. Further interaction and subsample analyses confirm that industry structure moderates the relationship between event-type ESG indicators and financial outcomes, demonstrating that firms in the service sector show greater financial sensitivity to ESG-related incidents.
Overall, ESG information demonstrates predictive power for financial performance; however, its effectiveness varies with the type of information and the industry structure. The findings of this study contribute to the literature on ESG information heterogeneity and industry-level moderating mechanisms, while also providing practical implications for sustainability communication, investment evaluation, and ESG rating system design. |
