在全球氣候變遷問題日益受到關注的背景下，本論文旨在探討自 2013 年至 2022 年美國企業的氣候變遷關注度與碳排放行為對其市場價值的影響。論文以美國標準普爾500指數中的公司作為研究對象，透過分析10-K報告中的氣候變遷關鍵字頻率，用以評估企業的氣候關注度。本研究運用多元迴歸分析顯示出企業的氣候關注度對市值有正面影響，碳排放對企業市值則具有顯著的負面影響，並發現自巴黎協議後，此負面影響呈現加劇的趨勢。此外，也確認了企業的氣候關注度與企業市值之間存在顯著的正相關。

Against the backdrop of increasing global attention on climate change, this paper aims to examine the impact of U.S. corporations' climate attention and carbon emissions behavior on their market value from 2013 to 2022. Focusing on companies listed in the U.S. Standard & Poor's 500 index, this study assesses corporate climate awareness by analyzing climate change keywords in 10-K reports. Employing multiple regression analysis, the study reveals that carbon emissions significantly negatively affect firm market value, with an intensified trend observed post-Paris Agreement. Additionally, a significant positive correlation between corporate climate attention and market value was confirmed.
