本論文企圖從政策的非意圖結果之研究角度，來探討近三十年來新公共管理 改革所可能產生的弔詭現象。弔詭現象的存在代表著公共政策體系必須同時滿足 相互衝突的價值目標，以及顯示出公共政策規劃與執行過程時常會招致非意圖結 果。本論文將結合RobertK. Merton的「有目的行動之非預期結果」觀點和公共 管理政策變遷之歷史制度論分析途徑，來探討這些弔詭現象產生的可能原因，並 期望對公共管理政策體系的深層結構和潛在價值衝突之緊張關係，能促進更深入之理解。

Adopting a lens of unintended policy consequences, this article attempts to explore the paradoxical phenomena New Public Management (NPM) Reform has produced over nearly three decades. These paradoxical phenomena represent contradicting value and goals which public policy system should satisfy simultaneously, and also indicate that public policy planning and implantation often give rise to unintended consequences. This article will try to combine Robert K. Merton5s perspective of “unanticipated consequences of purposive action” and a historical institutionalist approach to public management policy change to explore the possible causal explanations of theses paradoxical phenomena. In this way, it will help to enhance profound understanding of the deep structures and hidden value conflicts in public management policy system.
