隨著臺灣原住民族人口持續向都市遷移，都市原住民族已逐漸成為重要之政策與學術研究議題。桃園市為全國都會原住民族人口數最多之城市，長期透過各行政區辦理豐年祭儀，以促進文化傳承與族群認同，其運作仰賴民間基層組織桃園市原住民族協進會與政府機關協力合作共同推動。 本研究採質性研究取徑，透過深度訪談法、參與觀察法、次級資料分析及文獻分析法蒐集資料，並以桃園市行政區豐年祭為研究場域，運用資源依賴理論，分析地方政府、區公所與民間基層組織之間的資源互賴關係及權力互動模式，以理解公私協力治理之運作機制。 研究結果顯示，政府與民間基層組織之間呈現高度資源互賴關係。政府掌握財務、行政及制度性資源，而民間基層組織則具備文化祭儀專業知識、社群網絡動員能力及地方執行力，雙方透過資源交換共同推動豐年祭活動。雖然政府在經費配置、行政程序及制度規範上具有較強影響力，但民間基層組織憑藉文化權威與社群基礎展現其不可替代性，雙方在權力不對稱結構下仍維持平衡關係。此外，研究亦發現桃園市都市原住民族逐漸發展出兼具原鄉文化根源與都市生活經驗之都市原住民族文化，豐年祭已成為文化傳承、族群認同及社群凝聚的重要平台。 桃園市原住民族協進會因其文化特殊性，具備民間基層組織之文化及社群連結能力，是超越傳統行政協助角色，為政府與族人之重要中介者，本研究建議地方政府持續強化與民間基層組織之夥伴關係，健全組織運作制度，並協助建立多元財源機制，以提升其自主性與永續發展能力，共同維繫都市原住民族文化治理之運作。;With the continuous migration of Indigenous peoples in Taiwan to urban areas， urban Indigenous peoples have increasingly become an important subject of both policy discussion and academic inquiry. Taoyuan City， which has the largest urban Indigenous population in Taiwan， has long promoted cultural transmission and ethnic identity through district-level Indigenous harvest festivals held across its administrative districts. The implementation of these festivals is facilitated through collaboration between the Taoyuan City Indigenous Affairs Promotion Association， a grassroots organization， and government agencies. This study adopts a qualitative research approach and employs in-depth interviews， participant observation， secondary data analysis， and document analysis to collect data. Using district-level Indigenous harvest festivals in Taoyuan City as the primary research setting， the study applies Resource Dependence Theory to examine the resource interdependence and power interaction patterns among local government， district offices， and grassroots organizations， thereby exploring the operational mechanisms of public–private partnership governance. The findings reveal a high degree of resource interdependence between government agencies and grassroots organizations. Government agencies possess financial， administrative， and institutional resources， whereas grassroots organizations provide expertise in cultural rituals， community mobilization capacity， and local implementation capabilities. Through resource exchange， both parties jointly facilitate the organization of district-level Indigenous harvest festivals. Although government agencies exercise greater influence through budget allocation， administrative procedures， and institutional regulations， grassroots organizations maintain their indispensability through cultural authority and strong community foundations. Consequently， despite the existence of an asymmetrical power structure， both parties are able to maintain a dynamic equilibrium. Furthermore， the study finds that urban Indigenous communities in Taoyuan City have gradually developed a form of “new urban-rural culture” that integrates Indigenous homeland cultural roots with urban life experiences. District-level Indigenous harvest festivals have become important platforms for cultural transmission， ethnic identity formation， and community cohesion. Owing to its distinctive cultural characteristics， the Taoyuan City Indigenous Affairs Promotion Association possesses strong capacities for cultural preservation and community engagement. Its role extends beyond that of a traditional administrative support organization and has evolved into a crucial intermediary between government agencies and Indigenous communities. Accordingly， this study recommends that local governments continue to strengthen partnerships with grassroots organizations， improve organizational governance mechanisms， and support the development of diversified funding sources in order to enhance organizational autonomy and long-term sustainability， thereby contributing to the continued operation of urban Indigenous cultural governance.
