許多人長期以來皆有默默從事社會公益活動之習慣，藉以助弱勢族 群，利用捐款以及購買公益活動商品的來達成參與公益活動的使命感。已 有許多研究探討人們參與公益活動購買動機之眾多原因。當個人在支持一 項公益活動時，時常有多重動機存在，若能了解公益活動參與者購買動 機，將有助於公益活動策略的運用，並有利於主辦單位的規劃與辦理之 績效。本研究依據文獻蒐集將公益活動購買者之動機歸納為7個，分別 為休閒娛樂、自我利益、利他主義、慈善關懷、參考團體、商品實用性、 商品價格等。本研究希望探討這七個參與動機中，何者是在公益活動中 影響參與者購買的重要因素。 本研究運用調查法蒐集資料，再以灰聚類分析法發掘關鍵動機為 何。研究結果顯示，七個動機因素具有顯著差異。慈善博愛、利他主義 以及商品價格位於高標及中標，且無任何購買者回應落於低標，這表示 幾乎所有公益活動購買者均會是受到慈善博愛、利他主義以及商品價格 等要素所決定。相反的，休閒娛樂有66.67%、自我利益有63.33%落於低 標，這表示公益活動參與者購買動機甚少會受到休閒娛樂、自我利益等 因素所左右。此外，參考團體有及商品功能落於中標之比例分別為41%及48% ,皆遠高於其各自落於高標及低標之比例。這意謂著仍有相當比 例的購買者會受到參考團體及商品的功能與實用性等因素之影響。根據 以上結果，對於小型公益活動之義賣策略，本研究建議慈善組織的首要 任務是著重在慈善博愛、利他主義以及義賣商品價格，其次才是透過參 考團體的宣導及考量義賣商品的功能性為主軸，至於自我利益及休閒娛 樂等動機在本研究中所呈現出來之比例不高，可以忽略。
