面對治理環境複雜，如何提升公共服務的效率與效能成為政府主要課題。本文以從事家庭暴力防治業務的公部門、非營利組織、社工師事務所為研究對象，比較不同組織的社工在公共服務動機、激勵因素、人力招募重點、組織管理方式上的不同，並檢視成員的工作滿足與服務產出，來對新公共管理主張的市場模式與新公共服務提倡的協力觀點進行驗證。 研究過程中，發現社工師事務所的存在是一複合概念，是新公共管理之下代理化（agencification）觀點的體現，也是新公共服務組織人本主義的管理概念。本文並未對其明確定義，只關注於「良好組織管理」的特徵。社工師事務由於其具備彈性、目標單一的結構特質，再加上推行的授能式管理讓成員在工作上有較正面的情緒，更可凝聚成員向心力。相較於政府天生結構缺陷帶來的層級節制溝通不易，本文以為：代理化組織的鬆綁、彈性，或許不是一蹴可及，但在組織管理方式上使用Y理論授能式的激勵觀點，強調以人為本的管理技術，由內而外漸進式實施，是政府可以學習的方向。 / When the government faces governance crisis, new public management (NPM) and new public service (NPS) try to use two different ways to cure government failure. NPM emphasizes market-oriented to cure bureaucracy, while NPS prefers inter-sector cooperation. This study compares three different kinds of organizations: government agency non-profit organization and social service agency and all of them offers services of domestic violence protection. By comparing these three organization staff members, this study not only helps us to assess whether NPM or NPS is better but also gives government some advice on human resource management . The study finds that the social service agency is practicing one of NPM’s concepts: agencification, which is a flexible way to provide public service and NPS’s concept “organizational humanism” as its management skill. This study will not simply define whether the social service agency belongs to the public sector or the private sector. It just tries to suggest something helpful to employees and organization’s efficiency. The study finds out social workers in the social service agency are more positive in their work attitude and have high commitment to their organization due to its empowerment management while other organizations’ staff members have more complaints. Thus, the study concludes that joining NPM’s concepts- deregulation, flexibility and theory Y would make a win-win game between staff and organization.
