| Abstract: | 近年來，永續報告書已逐漸成為一門顯學，企業能透過其傳達自身在永續發展上的實踐與作為。隨著報告書如雨後春筍般發行，投資人與利害關係人也開始慢慢將焦點轉移到永續報告書的資訊揭露品質上，期望能辨別出不同品質的報告書，並研究其品質會如何影響到公司的績效，因此，本文旨在探討永續報告書的品質與企業市場績效間的關係。
本研究之樣本為2021年至2023年間台灣有發行永續報告書之上市櫃公司，以品質指數與可讀性分數來作為永續報告書品質的衡量指標，探討其與企業市場績效的關聯性。實證結果顯示永續報告書的認證與企業市場績效之間存在正向關係，此外，若企業選擇將永續報告書進行雙重認證，則能更進一步地提升其市場績效；在可讀性方面則是發現當企業永續報告書的可讀性愈差時，其市場績效愈佳，推測其背後原因，台灣企業永續報告書的可讀性愈低，可能意味著其使用了愈多永續相關的專業詞彙，旨在傳達自身在ESG方面實際的作為與貢獻，進而提升其在市場上的聲譽與價值。最後，本研究也發現，在台灣企業進行永續報告書認證時，不會因為選擇不同的認證單位(會計師事務所或其他第三方單位)，而對其市場績效產生顯著影響。
In recent years, sustainability reports have gradually become a significant focus, allowing companies to convey their practices and actions in sustainable development. As these reports spring up like mushrooms, investors and stakeholders have begun to shift their attention to the quality of information disclosure in sustainability reports. They hope to distinguish reports of varying quality and study how their quality impacts company performance. Therefore, this study aims to explore the relationship between the quality of sustainability reports and corporate market performance.
The sample for this study consists of listed companies in Taiwan that issued sustainability reports from 2021 to 2023. The quality of sustainability reports is measured using a quality index and readability score, exploring their relationship with corporate market performance. The empirical results indicate a positive relationship between the certification of sustainability reports and corporate market performance. Furthermore, if a company opts for dual certification of its sustainability report, its market performance is further enhanced. In terms of readability, it is found that the poorer the readability of a company's sustainability report, the better its market performance. It is speculated that the lower readability of Taiwan's corporate sustainability reports may indicate the use of more specialized sustainability-related terminology, aiming to convey their actual actions and contributions in ESG, thereby enhancing their reputation and value in the market. Finally, this study also finds that the choice of different certification bodies (accounting firms or other third-party organizations) for sustainability report certification does not significantly impact the market performance of Taiwanese companies. |
