城鄉生產鏈結：工地圍籬綠美化治理網絡個案研究

Abstract

本研究旨在探討工地圍籬綠美化的生產過程中，城市建案工地與鄉村園藝生產的治理網絡及其所可能產生的綠美化議題。隨著都市化擴張帶來的環境汙染，透過自然改善都市環境品質成為重要課題。由於傳統平面綠化不敷滿足都市綠化需求，因此，立體綠化應運而生，工地圍籬綠美化成為現今建築工地重要的臨時綠化設施。 本研究採用批判民族誌視角，結合行動者網絡和利害關係人理論，選擇城市和鄉村作為田野案例，深入剖析綠圍籬治理網絡的運作過程，並探討其作為綠色治理的實踐意涵。研究首先從政策制度的角度出發，回顧並分析台北市綠美化的發展歷程，探討綠色治理如何逐步轉化成為台北市的核心治理策略。其次，從技術實踐的角度，探討鄉村生產者與都市營建者生產綠圍籬的過程。最後，運用行動者網絡與利害關係人理論探討多方行動者之城鄉生產鏈結關係。 研究發現，綠圍籬治理網絡是城鄉協作與資源共享的重要體現，然而，卻也面臨著諸多挑戰與困境，例如預算限制、政策與需求不符、植栽供應鏈問題、資源浪費等多重困境。此外，本研究更進一步揭示政策制定與實際執行之間的斷裂問題，包含行動者間的權力不對等以及都市環境未真實改善的漂綠現象。 與過往對於綠圍籬持正面觀點的研究不同，本研究採取批判性立場，嘗試探討綠圍籬的困境與挑戰，並為此提出一系列政策建議。這些建議包括調整綠圍籬的設置標準、落實植栽永續化以及探索替代性美化方案等，旨在減少資源浪費、降低管理成本並提升環境效益，從而促進更有效益的綠色治理實踐。

This study examines governance networks in construction site greening and rural horticultural production, addressing potential green beautification issues. Urbanization and environmental pollution have raised concerns about improving urban environmental quality. Traditional flat greening is insufficient for urban needs, leading to the emergence of vertical greening, including " Greening and Beautification of Construction Fence ", which is the crucial temporary Greening facility in modern building lots. This research combines actor-network theory and stakeholder theory, analyzing from a critical ethnographic viewpoint. Through urban and rural case studies, it analyzes the operation and meaning of green fence governance networks as a form of green governance. First, it explores Taipei City's greening development from a policy perspective. Secondly, it studies the production process of green fences for both rural producers and urban constructors from a technical standpoint. Finally, Actor-network and stakeholder theories are applied to examine urban-rural production chain connections. The study finds that the green fence governance network is a significant manifestation of urban-rural cooperation and resource sharing, but it also faces various challenges and dilemmas such as budget constraints, policy mismatches with demands, plant supply chain issues, and resource wastage. Moreover, it reveals the disconnect between policy formulation and actual implementation, including power imbalances among actors and the phenomenon of "greenwashing" where urban environments do not genuinely improve. Unlike previous studies with positive perspectives on green fences, this research adopts a critical stance to address challenges. Policy recommendations include adjusting green fence standards, implementing sustainable planting strategies, and exploring alternative beautification options to promote effective green governance practices.
