文化是個有機體，會隨著外在時空環境改變而調整，因此具有傳承性、自發性、普遍性、特殊性、變異性。一旦調適不良，也有可能如同人一般，歷經衰老、甚至遭到淘汰。本研究以節慶體現一地文化意涵為出發點，聚焦於富有濃厚族群特色的客家節慶，並選定近年來擴大規模舉辦之臺中市東勢區新丁粄節，探討山城東勢客家族群之地域性、族群性，以及節慶如何在不斷成長的大環境中，蛻變成現今之樣貌。本文首先從東勢的區域所在及族群分布之文獻，印證東勢地區與客家族群之淵源，並循著傳統食物「粄」的路徑，去一探新丁粄節之原貌。其次藉由閱讀新丁粄節活動企劃書、整理近十年的報章內容，以及田野調查與實地專訪等，互相比較、分析，一一刻劃出節慶之發展軌跡，勾勒新丁粄節十年來的變與不變。究竟，東勢新丁粄節如何在新時代的環境衝擊下找到發展方向，面對傳統文化與現代生活的衝突，又是如何在原始節慶精神與新興節慶活動上找到平衡，體現臺灣的客家節慶文化，種種疑問，皆是本研究所探討的重要課題。
