本研究以桃園市平鎮區忠貞市場改建為例，探討客庄傳統市場改建過渡期間，空間重組、制度介入、公民參與與公共價值建構之間的關係。忠貞市場兼具交易、地方生活與多元飲食功能。研究採質性方法，透過文獻分析、田野觀察及半結構式訪談，了解不同市場行動者的使用、經營與參與經驗。 研究發現，市府以「先建後拆」方式設置臨時市場、安置部分攤商並改善周邊道路，使分散的市場活動逐步進入較明確的空間與管理關係；但臨時市場未取代周邊原有活動，市場內外仍共同構成居民的市場生活圈。不同經營者因原有位置、經營方式及是否取得臨時攤位而面臨不同調整。現有資料可確認納入、經營調整及空間使用受限，尚不足以認定已形成排除結果。改建已有資訊傳達、討論及意見表達管道，但不同市場行動者參與程度不一，從提出問題到了解後續處理仍有落差。 本研究認為，忠貞市場的公共價值不只在改善安全、衛生、交通與管理，也包括居民使用便利、攤商持續經營、熟客關係、多元飲食及市場內外生活連結的延續，並在改建、實際使用與持續調整中逐步形成。政策上建議建立持續溝通與回應機制，在共同規範下保留適度經營彈性，串連市場內外活動，並評估發展香料集散與轉運功能，以延續市場生活圈與地方特色。;This study examines the redevelopment of Zhongzhen Market in Pingzhen District， Taoyuan City， to explore the relationships among spatial restructuring， institutional intervention， citizen participation， and public value creation during the transitional redevelopment of a traditional market in a Hakka community. Zhongzhen Market serves not only as a place of commercial exchange but also as a setting for local everyday life and diverse food cultures. Adopting a qualitative approach， this study uses document analysis， field observation， and semi-structured interviews to understand the experiences of different market actors regarding market use， business operations， and participation. The findings indicate that the city government adopted a “build first， demolish later” approach by establishing a temporary market， relocating some vendors， and improving surrounding roads. These measures gradually brought previously dispersed market activities into clearer spatial and administrative arrangements. However， the temporary market did not replace the existing commercial activities in the surrounding area. The temporary market and its surroundings continue to form an interconnected sphere of everyday market life. Vendors faced different adjustments depending on their original locations， business practices， and whether they obtained stalls in the temporary market. The available evidence confirms inclusion， operational adjustments， and restrictions on the use of space， but remains insufficient to conclude that exclusion has occurred. Although channels for information sharing， discussion， and opinion expression were available during redevelopment， levels of participation varied among market actors， and a gap remained between raising concerns and understanding how they were subsequently handled. This study argues that the public value of Zhongzhen Market lies not only in improving safety， sanitation， traffic conditions， and market management， but also in maintaining convenient access for residents， the continuity of vendor operations， regular-customer relationships， diverse food cultures， and connections between the market and its surrounding community. Public value is gradually created through redevelopment， actual use， citizen participation， and continuing adjustment. Policy recommendations include establishing sustained communication and response mechanisms， preserving appropriate operational flexibility under common rules， strengthening connections between activities inside and outside the market， and assessing the potential development of Zhongzhen Market as a hub for spice aggregation and distribution.
