本研究旨在探討下游企業是否能透過永續供應鏈成果之揭露與供應商行為準則機制以降低上游供應商的永續脫鉤行為，並進一步分析媒體關注度之果。研究樣本以2020 年至2023 年台灣上市公司中擔任下游客戶角色者，並依其年報揭露之供應商資料進行配對，建立上下游關係配對觀察值。資料來源包括台灣經濟新報資料庫（TEJ）、 公司年報、永續報告書、公開資訊觀測站與Google Trends。本研究採用邏輯斯迴歸分析，檢視下游企業永續管理作為對上游供應商永續脫鉤的影響，並進一步以公司新聞搜尋熱度作為媒體關注度之代理變數進行樣本分組，比較其影響效果。實證結果顯示，當下游企業揭露永續供應鏈成效並要求行為準則之簽署，能有效降低上游供應商永續脫鉤的風險。而在下游企業本身被外界高度關注之情境下，更能降低供應商永續脫鉤的行為。;This study seeks to ascertain whether downstream firms can reduce unsustainable practices within their upstream supply chains through the implementation of supplier code of conduct and the disclosure of sustainable supply chain performance. Furthermore, this study investigates the influence of media attention on the correlation between these two practices and upstream supplier misconduct. This research examines publicly traded Taiwanese firms serving as downstream clients from 2020 through 2023, utilizing supplier disclosures within annual reports to create paired supply chain datasets. The Taiwan Economic Journal (TEJ) database, company annual reports, sustainability reports, the Market Observation Post System (MOPS), and Google Trends constituted the data sources for this research. Subsequent segmentation of the sample was performed to analyze the impact of media attention. Findings demonstrate a significant correlation between the implementation of supplier code of conduct combined with the disclosure of sustainable supply chain management performance by downstream firms, and a reduction in upstream supplier sustainability decoupling. This effect is amplified under conditions of heightened media scrutiny.
