一九八０年以來政府再造蔚為世界風潮，組織改造工程為各國因應財政壓力及行政效率低落的重要基礎建設。蕭萬長內閣啟動精省列車，陳水扁總統重啟行政院組織法修正，皆有龐大政治效應，如何經驗接軌，為本文研究之動機。經由分析整理相關理論，探討組織重組可能的成因和動力，並藉由內政部精省第二階段組織調整作業之個案分析，希望透過理論的粹煉和展演，提昇組織重組的執行力，俾全面提昇政府效能，最後作者提出八項結論及八項建議。結論部分計列：一、影響公共組織組織重組因素中，以政治因素居首，其次為經濟因素，管理因素影響最微。二、組織重組機會之窗的開啟需以有重大事件為先決條件。三、組織重組的動力依序源於民意機關、上級機關及行政首長。四、組織重組方案係理性規劃或非理性規劃，端視其內、外推拉力量而定。五、組織調整方案應重視配套法案及其立法優先順序。六、組織調整方案應兼具穩健及開創性。七、第二階段精省作業強調員額精簡。八、第二階段精省組織調整之最大特色即組織法律制（修）定及暫行組織規程修訂案雙軌併行等八項。建議部分計列：一、組織改造核心理念應為政府職能調整，即為塑身，非瘦身。二、重視組織法制變革作業，且應有配套及優先審議順序。三、為顧及原省府員工權益，行政院應同意部會地區辦公室職務列等得逕依部會標準調列。四、組織重組方案應兼及穩健及開創性。五、組織重組方案合法化過程，應建立立法、行政及輿論之多數聯盟以爭取政治支持。六、應強化機關首長執行之意志。七、組織重組過程應重視員工權益，惟亦應避免人才反淘汰。八、訂定日出條款以縮短組織調整過渡期，避免組織動盪不安等八項。 / Since 1980 the government restructuring is the trend, the enginge of the organization reform is an important infrastructure to deal with the financial pressure and the loweringly administrative efficiency.
