本研究以台灣2015年至2023年間有在公開資訊觀測站揭露碳排放量資訊之上市櫃公司作為研究對象,探討了內部控制缺失是否會增加碳風險對債務資金成本的影響,並且進一步探討在2023年1月10日修法「氣候變遷因應法」後,這一關聯性是否會進一步強化。實證結果顯示,相對於沒有內部控制缺失的高碳排公司,有內部控制缺失的高碳排公司,因為有較高的碳風險,而產生較高的財務成本。然而,在2023年1月10日修法「氣候變遷因應法」後,此關聯性並未進一步強化。;This study examines public-listed companies in Taiwan that disclosed carbon emission information on the Market Observation Post System from 2015 to 2023. It investigates whether internal control weaknesses increase the impact of carbon risk on the cost of debt and further explores whether this relationship is strengthened after the amendment of the "Climate Change Adaptation Act" on January 10, 2023. The empirical results show that high-carbon-emission companies with internal control weaknesses incur higher financial costs due to higher carbon risk compared to high-carbon-emission companies without internal control weaknesses. However, this relationship did not further strengthen after the amendment of the "Climate Change Adaptation Act" on January 10, 2023.
