Abstract:	本研究以 2016 至 2024 年台灣上市非金融業公司為樣本，探討 ESG（環境、社會、公司治理）表現對機構投資人持股行為之影響，並進一步檢驗研發支出是否於其中扮演中介機制。研究採用固定效果模型與分組迴歸分析，並納入時間滯後設計，以觀察 ESG 資訊對投資決策之跨期影響。我們發現，整體 ESG 評分僅對投信法人持股呈現穩定且顯著的正向關聯；外資與自營商則未展現一致反應，顯示不同機構投資人對 ESG 表現之敏感程度具有顯著異質性。進一步拆解 ESG 三大構面後發現，投信法人對環境構面特別敏感，顯示企業若在環保作為上表現良好，將更容易吸引投信資金配置；外資則主要關注公司治理表現，對環境與社會面之回應相對保守；自營商則未對 ESG 任一構面產生顯著反應，反映其投資策略較不受永續資訊驅動。進一步的中介效果分析顯示，企業研發支出可部分傳導 ESG 整體評分對投信法人持股的影響，但此中介機制對外資與自營商並不成立。此外，ESG 評分對投信法人持股具有顯著的時間遲延效果，說明投信法人在投資決策上會持續追蹤並回應企業的永續表現。整體而言，研究結果支持 ESG 表現對機構法人投資決策存在顯著影響，且此影響方向與程度依法人類型而異。企業若能將永續策略與研發創新有效整合，將更有可能獲得具長期投資取向之機構法人青睞。 ;The main purpose of this research examines the impact of corporate ESG (Environmental, Social, and Governance) performance on institutional ownership, using panel data from Taiwan-listed non-financial firms between 2016 and 2024. This study not only analyzes the effects of both overall ESG scores and individual dimensions (ENV, SOC, GOV), but also explores whether R&D intensity acts as a mediating mechanism. Furthermore, it investigates investor heterogeneity by categorizing institutional investors into foreign investors, mutual funds, and dealers, while also incorporating a time-lagged design to test for delayed investment responses to ESG information. The empirical results indicate that ESG performance positively influences mutual fund ownership, particularly through the environmental dimension, while foreign investors respond significantly to governance performance only. Dealers show no consistent response to ESG factors. Evidence of mediation via R&D is limited, and only partially supported within the mutual fund sample. Time-lagged models reveal that ESG information has a deferred effect on mutual fund investment decisions. Overall, this study highlights the differentiated preferences among investor types and suggests that ESG performance, when aligned with innovation strategies, can enhance firm appeal to long-term capital providers.
