由於社會環境的急劇變遷，公部門扮演之角色，不若往昔僅僅處於被動服務態勢，主動出擊已成為必要作為。且地方政府各項服務措施與人民日常洽公辦理之事務息息相關，因此為了符合民眾期待進而感動民眾，各地方政府不僅意識到「服務」與「創新」的重要性，也不斷地藉由各類創新以及便民措施的精進，來提高民眾對於政府的信賴，「服務創新」因而成為地方政府展現積極作為的一個代表性象徵。 而政府資源「取之於民，用之於民」，任何政策的推動不應因為大部份民眾的漠視與無考量成本與公共利益的旨向，而貿然推動缺乏照顧弱勢的福利政策。故本文以服務創新文獻以及政策評估之相關理論為基礎，評估新北市政府於102年推動「跨區服務」政策產生之副作用為何，藉以提出短、中長期之政策建議。採用之評估模型則以Vedung之副作用模型(side-effect model)為基礎，結合Dunn所提出之評估的標準形式，即效能性、效率性、充分性、公平性、回應性、適當性等面向，從政策規劃端、政策執行端與政策接收端（含受益者與其利害關係人）三類別為分析面向，從深度訪談與描述性統計角度，探討該政策在人力、成本與服務上所產生之可預期與非預期之副作用。 / Due to rapid change of social environment, the public sector no longer plays a passive role in service delivery. It is essential for it to take a more active role. It is especially true for local governments, as their functions are closely related to the people’s daily lives. In order to meet the expectations of the people and get them moved, various local governments are not only aware of the importance of "service" and "innovation", but also continue to formulate various innovation and convenience measures to enhance the people's trust to the government. "Service innovation" has become a symbol to show an activism of local governments. Government resources come from the people, so they should be used for the people. We should not take no account of cost and public interest in figuring out a welfare policy for the disadvantaged. Therefore, this thesis makes use of the literature of service innovation and the theory of policy evaluation to assess the side effects generated by the "cross-district service" policy initiated by the New Taipei City Government in 2013, in order to suggest some short-, medium- and long-term recommendations. The evaluation model this thesis adopts is based on Vedung’s side effects model accompanied with Dunn’s evaluation criteria: effectiveness, efficiency, adequacy, fairness, responsiveness and appropriateness. The analytical dimensions are composed of the points of policy planning, policy implementation and policy receiving (including beneficiaries and other stakeholders). Through in-depth interviews along with descriptive statistical analysis, it explores anticipated and unanticipated side effects of the policy generated in terms of manpower, cost and service.
