社會企業是因應弱勢族群的需求，或是公益與社會價值理念而成立，不同於一般企業因為市場需求與利潤動機之形成，社會企業強調透過企業的手段解決社會問題，焦點在於社會、經濟與生態環境三重底線之價值。本研究以光原社會企業股份有限公司與瑪納有機文化生活促進會作為個案分析。光原社會企業幫助嘉義阿里山鄉原住民部落建構完整有機農業產銷價值鏈網絡體系，而瑪納則是深入原住民部落推廣有機農作種植，友善環境與土地，以及解決原住民部落的社會問題，兩者共同為原住民經濟產業找尋出路。本研究目的為探討光原與瑪納推動社會企業的經營模式，以及其對原住民部落產生的社會效益與影響。在研究方法上，採取文獻分析，以及針對個案的決策者進行深度訪談，期望建構社會企業在原住民部落的經營模式，而預期研究成果，可以做為其他原住民部落推動社會企業之參考。
