| Abstract: | 在極端氣候加劇影響，ESG (Environment、Social、Governance)永續發展被視為最重要之課題之一，在資本市場發展上，綠色金融已成為全球最重視的核心價值，其中綠色債券與可持續債券(稱綠色債券)作為專門為環保項目融資或再融資的固定收益工具，在推動向低碳經濟轉型發揮著重要作用。本研究探討綠色認證與否(是否符合綠色債券)對債券定價是否造成顯著差異，以及加入信用評等、發行人產業類別、不同債券期間與上市區域等變因對該顯著程度的影響；本研究針對2022年初至2023年3月15日期間，全球所發行的美元債資料進行詳細的分析。
主要研究結果為(1) 針對本研究取樣期間發行的美元債，經統計檢定驗證綠色認證對其定價具有顯著影響，該期間平均綠色債券溢價(Green Bond Premium, 即綠色溢價)為83.81bps。(2)非投資級債券的綠色溢價較投資級債券更為顯著。(3)瀕臨信用評等懸崖級距之債券的綠色溢價平均值呈現負值，包括BBB區間或淪到CCC評等的B區間。(4)產業分布方面，一般企業與金融業相較於國有企業與公用事業而言，其所發行的債券享有較高綠色溢價。 (5)在歐洲區域上市的債券相較於其他區域呈現顯著的綠色溢價。
Under the impact of intensified extreme climate, ESG (Environment, Social, Governance) sustainable development is regarded as one of the hottest topics today. In the development of the capital market, green finance has become the most important core value in the world. Among various financial instruments, green bonds and sustainable bonds (i.e., green bonds) play a crucial role in facilitating the financing or refinancing of environmentally friendly projects, thus driving the transition towards a low-carbon economy. The purpose of this study is to explore whether green certification (eligible for green bonds) has a significant difference in bond pricing, and the impact of variables such as credit rating, issuer industry category, different bond periods, and listing regions on this significant degree. This study conducts a detailed analysis of the US dollar bonds issued globally from the beginning of 2022 to March 15, 2023.
The results show that: (1) For the US dollar bonds issued during the sampling period of this study, it has been verified by statistical verification that green certification has a significant impact on their pricing. The average green bond premium (Green Bond Premium, i.e., green premium) during this period was 83.81bps. (2) Non-investment-grade bonds exhibit a more significant green premium compared to investment-grade bonds. (3) Bonds on the verge of rating cliffs, including those in the BBB range or those in the B range that may be downgraded to CCC rating, show negative green premiums. (4) In terms of industry distribution, bonds issued by general corporations and financial institutions enjoy higher green premiums compared to state-owned enterprises and utilities. (5) Bonds listed in the European region have the most significant green premium compared to other regions. |
