Abstract: 本研究旨在探討台灣金融控股公司(FHC)之環境、社會與治理(ESG)表現,如何透過外溢效應(Spillover Effect)影響其旗下證券子公司的財務績效。在全球ESG浪潮下,過往研究多聚焦於單一企業或銀行業,忽略了金控集團內部母子公司間的價值傳導機制,以及證券產業的獨特脈絡。本研究的重要性在於填補此一文獻缺口,並觀察金控集團 ESG 表現對其集團內影響。
本研究以理論為基礎,提出母公司的ESG表現可透過三大機制產生外溢效應:(一)聲譽與品牌資產外溢,藉由「月暈效應」與累積「道德資本」,提升子公司品牌形象與風險抵禦能力;(二)財務資源外溢,透過降低集團整體資金成本,並經由內部資本市場進行策略性資源配置;(三)策略與營運能力外溢,經由知識轉移與創新擴散,提升子公司的核心競爭力。
為驗證上述機制,本研究選取2017年至2024年間台灣所有上市金融控股公司共14間及其主要證券子公司共14間為樣本,採用台灣經濟新報(TEJ)資料庫之ESG評分與財務數據,建立追蹤資料固定效果模型進行實證分析。
本研究結果發現金控母公司的ESG表現確實能顯著提升證券子公司的資產報酬率(ROA)、股東權益報酬率(ROE)及每股盈餘(EPS)。本研究替ESG與企業績效的關聯性提供了集團層級,亦對金控公司、投資人及主管機關提出具體建議:金控應將ESG視為集團層級的策略性投資;投資人在評估子公司時應將母公司ESG表現納入考量;而主管機關由上而下的監管政策,是提升整體金融業永續性的有效途徑。
This study examines how the Environmental, Social, and Governance (ESG) performance of financial holding companies (FHCs) in Taiwan influences the financial performance of their securities subsidiaries through spillover effects. While prior ESG research has largely focused on individual firms or the banking sector, this study highlights intra-group transmission mechanisms and addresses the unique role of the securities industry—an area that remains underexplored.
Building on theoretical foundations, we propose three channels of ESG spillover: (1) reputational spillover, via halo effects and moral capital; (2) financial spillover, through reduced capital costs and internal capital allocation; and (3) strategic spillover, driven by knowledge transfer and innovation diffusion.
Using panel data from 14 listed FHCs and their securities subsidiaries from 2017 to 2024, we apply a fixed-effects model with ESG ratings and financial indicators from the Taiwan Economic Journal (TEJ). Empirical results show that parent-level ESG performance significantly enhances subsidiaries’ ROA, ROE, and EPS.
Our findings underscore the strategic importance of ESG at the group level and suggest that regulators, investors, and FHCs should account for ESG spillovers in performance evaluation and policy design.
