在克服疫情所帶來的挑戰並應對科技快速變遷的時刻，企業為了在競爭激烈的環境中生存，特別關注員工的流動率和人才留任問題。因此，提高員工的任務效能成為確保企業組織穩健運作永續經營的重要策略，以提升競爭力和實現長期發展目標。在這種背景下，管理層也逐漸開始重視僕人式領導此一領導方式發揮的效用。過去研究已證實僕人式領導對員工行為有著正向關聯，但少有研究探討工作效能與員工個人心態於其中的調節或中介作用。因此，本研究旨在探討實施僕人式領導，透過職涯適應性對員工任務績效的影響，並加入員工個人積極主動性格作為調節式中介角色。本研究以主管和部屬配對問卷為研究樣本發放並回收了226份有效問卷，研究結果主要發現：（1）僕人式領導行為與部屬任務績效呈現正向關聯。（2）部屬職涯適應性在僕人式領導行為與部屬任務績效間具有中介效果。（3）部屬積極主動性格在職涯適應性與僕人式領導者間不具有調節效果。（4）部屬積極主動性格在僕人式領導與部屬職涯適應性及部屬任務績效間不具有調節式中介效果。最後，根據研究結論提出了研究貢獻、管理意涵和未來研究方向等建議。

At a time when we are overcoming the challenges posed by the epidemic and responding to rapid changes in technology, companies are paying special attention to employee turnover and talent retention in order to survive in a highly competitive environment. Therefore, improving employees' task efficiency has become an important strategy to ensure the stable operation and sustainable operation of corporate organizations, so as to enhance competitiveness and achieve long-term development goals. In this context, management has gradually begun to pay attention to the effectiveness of servant leadership as a leadership method. Past research has confirmed that servant leadership has a positive correlation with employee behavior, but few studies have explored the moderating or mediating role of work effectiveness and employees' personal mentality. Therefore, this study aims to explore the impact of servant leadership on employees' task performance through career adaptability, and to add employees' personal proactive personality as a moderating mediator. This study used the supervisor-subordinate paired questionnaire as a research sample and issued and collected 226 valid questionnaires. The main findings of the study are: (1) Servant leadership behavior is positively related to subordinate task performance. (2) Subordinate career adaptability has a mediating effect between servant leadership behavior and subordinate task performance. (3) The proactive personality of subordinates does not have a moderating effect between career adaptability and servant leaders. (4) The proactive personality of subordinates does not have a moderating mediating effect between servant leadership and subordinates' career adaptability and subordinates' task performance. Finally, based on the research conclusions, suggestions such as research contributions, management implications and future research directions are put forward.
