近年來，隨著全球永續意識的興起，企業是否善盡社會責任受到大眾的高度關注，為了與利害關係人進行有效的溝通，企業開始強化永續資訊揭露，以展現其永續經營的成果。本研究探討企業社會責任報告書及重大性矩陣的揭露對財務績效及公司價值的關聯性，並以迴歸模型進行實證分析。研究對象為台灣上市櫃食品工業與農業科技業公司，研究期間為2011年至2020年，共計305筆觀察值。實證結果發現：企業社會責任報告書及重大性矩陣的揭露與公司價值呈顯著正向關聯，顯示揭露永續資訊能為企業帶來正向影響力，如揭露重大性議題分析之資訊能增進與利害關係人的溝通，並減輕重大議題可能帶來的風險。此外，重大性矩陣的揭露與財務績效呈顯著負向關聯，顯示執行重大性議題分析須經繁瑣的程序，對企業而言耗時且費力，故將使營運成本增加，影響短期獲利能力。
本文研究貢獻有三：第一，回應聯合國永續發展目標第二項「確保糧食安全，消除飢餓，促進永續農業」。第二，以「企業是否有揭露重大性矩陣」為標的進行實證研究，為永續資訊揭露之研究提供新的證據。第三，近期烏俄戰爭影響，引發國際糧食危機，帶動農糧概念股上漲，故食品類之研究更顯重要。本文管理意涵有二：第一，永續投資概念盛行，企業應更注重永續資訊揭露的品質與內容。第二，未來主管機關應透過更詳盡且完善的審查機制，確保資訊揭露的真實性。

In recent years, whether businesses fulfill their social responsibilities has attracted attention from the public with the rise of global awareness of sustainability. Therefore, companies are committed to strengthening the sustainability reporting to build a communication bridge with stakeholders. This study examines the relationship between corporate social responsibility and materiality matrix disclosure on financial performance and firm value by taking Taiwanese listed food and agricultural technology companies as samples. This study uses 305 observations from 2011 to 2020. The empirical results show that corporate social responsibility and materiality matrix disclosure have positively related to firm value significantly, and materiality matrix disclosure has a significant negative correlation with financial performance. In conclusion, sustainability reporting has a positive impact on the firm value of an enterprise, such as conducting a material analysis to enhance communication with stakeholders and mitigate possible risks arising from material issues, but it will also increase the operating costs and affect the profitability of the enterprise at the same time.
