Introduction: 本系夜間部創立於民國53年，原名為合作學系。後因「合作」一詞之定義每有廣狹之別，易生誤解，乃於民國64年3月奉教育部核准，更名為合作經濟學系。鑑於人類具有理性，其決策行為的各種問題皆可以經濟理論解釋，加之經濟學是關乎國計民生的經世致用之學，故於民國69年2月經教育部核准，再將合作經濟學系更名為經濟學系，以配合時代潮流與社會需要，培育經濟專業人才，參與國家經濟建設行列。爾後又因社會環境趨於多元化與專業化，更需要大量之專業經濟分析人才，教育部特於75年度核准本校增設日間部經濟學系一班。民國86年起，本系配合教育部新制，將夜間部改為正規學制，自此本系不再招收夜間部學生，日間部則由一班增為三班。本系之「碩士班」已於九十學年度起招生，使本系畢業生增加一個進修管道，不但有助提升讀書風氣，對系上教師研究工作的進行也有助益。本系一方面秉承優良學術基礎，釐定完善的經濟學教學規畫，積極培養頭腦敏捷、視野恢宏之經濟人才；另一方面則依據本校一貫「結合學術與社會、以學術服務社會」之政策，鼓勵並全力協助本系教師與政府及民間相關機構合作，從事總體經濟、產業政策、勞動經濟、能源經濟、計量經濟與經濟政策等之研究，同時積極推展建教合作計畫，以培養具實務經驗的經濟專才。另於101學年度因應學院整合政策，原於商學院之下，現改隸屬於商管學院中。
