隨著國際與國內永續法規日趨嚴謹，企業面臨轉型壓力與綠色職能匱乏瓶頸，使得知識流程外包（KPO）成為獲取專家知識的理性戰略選擇。然而，目前市場對永續顧問缺乏統一標準，品質不一且存在資訊不對稱。有鑑於此，本研究以 KSAO 模型為理論基礎，建構系統化的「資深永續顧問專業職能量表」，以為企業篩選外部專家提供客觀依據。 本研究採用修正型德菲法（Modified Delphi Method），邀請 19 位資深專家組成評審小組，歷經兩輪問卷調查，並透過「重要性-凝聚度象限矩陣」進行交叉分析。研究結果成功從初始 48 項指標中篩選並確立出 43 項核心行為指標（包含知識 8 項、技能 14 項、能力 9 項及其他特質 12 項）。 研究核心發現顯示，當前台灣市場對法規合規與環境風險管理的迫切性遠高於社會衝擊評估，導致社會報酬率（SROI）及多元平等共融（DEI）指標因未達重要性或共識門檻而遭刪除。此外，隱性能力與特質是區別資深顧問績效表現的關鍵分水嶺，在 12 項高重要性指標中占了 75%，並以溝通協調、前瞻策略思考及信任建立最受重視。本研究填補了外部顧問職能研究的學術空白，亦為企業外包篩選提供客觀檢核工具。;With global and domestic sustainability regulations becoming increasingly stringent， enterprises face transition pressures and bottlenecks due to a scarcity of green competencies， making Knowledge Process Outsourcing (KPO) a rational strategic choice for acquiring expert knowledge. However， the current market lacks unified and clear standards for sustainability consultants， resulting in inconsistent quality and high levels of information asymmetry. In view of this， this study uses the KSAO model as its theoretical foundation to construct a systematic "Professional Competency Scale for Experienced Sustainability Consultants，" providing an objective basis for enterprises to screen external experts. This research adopts the Modified Delphi Method， inviting an expert panel of 19 experienced specialists to participate in a two-round questionnaire survey， followed by a cross-analysis using the Importance-Cohesiveness Matrix. The results successfully filtered and established 43 core behavioral indicators from the initial 48 items， comprising 8 items for Knowledge， 14 items for Skills， 9 items for Abilities， and 12 items for Other characteristics. The core findings indicate that the current Taiwanese market prioritizes regulatory compliance and environmental risk management over social impact assessments， which led to the elimination of Social Return on Investment (SROI) and Diversity， Equity， and Inclusion (DEI) indicators for failing to meet the required importance or consensus thresholds. Furthermore， implicit abilities and personal traits serve as the critical watershed distinguishing the performance of experienced consultants， accounting for 75% of the 12 high-importance indicators， with communication and coordination， forward-looking strategic thinking， and trust-building being the most heavily emphasized. This study fills the academic gap in the literature regarding external consultant competencies while offering a practical check tool for corporate outsourcing selection.
