本研究旨在探討 OECD 稅基侵蝕與利潤移轉（BEPS）行動計畫與 FATF 防制洗錢金融行動工作組織40項建議之協同作用，並以美國安隆案為例，檢視現代監管架構能否防堵類似金融犯罪。本研究採質性個案研究法，建構「國際租稅改革與洗錢防制協同治理架構」。研究發現，安隆案利用特殊目的實體（SPEs）之洗錢手法若置於今日環境，將面臨跨制度的三道防線阻絕：（1）透明度協同：BEPS 行動 13 國別報告（CbCR）結合 FATF 實質受益權規範，能穿透 SPEs 外觀，揭露利潤與經濟活動脫鉤之異常；（2）實質性協同：移轉訂價經濟實質原則與強制揭露規則（MDR），配合守門人查核義務，能有效識別缺乏商業理由之虛假交易；（3）誘因阻斷協同：混合錯配規則與全球最低稅負制（Pillar Two），協同國際資訊合作，消弭監管套利空間與補足稅負，從根本瓦解利用離岸結構洗錢與避稅之經濟誘因。結論指出，兩大制度之協同作用顯著提升犯罪結構之維持成本與法律風險，透過資訊交換與實質審查之整合，達成維護金融誠信與租稅公平之雙重目標。

This study explores the synergistic effects between the OECD’s Base Erosion and Profit Shifting (BEPS) Action Plan and FATF’s anti-money laundering (AML) standards. Using the Enron case, it examines whether modern regulations can prevent similar financial crimes. Adopting a qualitative case study approach, the research constructs a collaborative governance framework. The findings indicate that Enron’s laundering techniques would face three lines of defense today: (1) Transparency Synergy: Country-by-Country Reporting (CbCR) and beneficial ownership standards would expose the decoupling of profits from economic activities in Special Purpose Entities (SPEs) ; (2) Substance Synergy: Economic substance principles for transfer pricing and Mandatory Disclosure Rules (MDR), combined with gatekeeper due diligence, would effectively identify fictitious transactions; and (3) Incentive Disruption Synergy: Hybrid mismatch rules and the Global Minimum Tax (Pillar Two) would eliminate regulatory arbitrage and dismantle the economic incentives for offshore structures. The study concludes that the convergence of tax reform and AML regulations significantly increases the costs and legal risks for criminal structures, achieving the dual goals of financial integrity and tax equity.
