本研究目的旨在應用類別變數DEA（Categorical variable data envelopment analysis） 評估新北市新店區公私立高中職學校之經營效率，首先不考慮其群組性質直接運用DEA 方法進行經營績效評估，再次考慮其群組性質先行分類並結合類別變數分析進行經營績效評估，顯示十二年國教免學政策確實有效提升職業學校經營效率，且類別變數 分析評估模式優於一般DEA 方法。

The purpose of this study is to apply categorical variable DEA in evaluating operational efficiency of twelve-year public for senior high and higher vocational school in Xindan area, new Taipei city.
