行动者网络视域下社区花园赋能可持续城市更新OA

China's urban renewal paradigm is undergoing a fundamental transformation.The dominant model,long characterized by"hardware renewal"centered on large-scale housing demolition,infrastructure overhaul,and physical reconstruction,is gradually giving way to a"software renewal"approach that prioritizes the coordinated development of social fabric,economic vitality,and ecological sustainability.Within this evolving context,community gardens have emerged as a significant grassroots innovation practice.By revitalizing idle and underused urban spaces,activating latent community capital,fostering genuine public participation,and enhancing urban resilience,these micro-scale green interventions offer a promising pathway toward more inclusive and sustainable urban futures.This study investigates the micro-governance mechanisms that drive sustainable urban community renewal,with a specific focus on community garden construction as a vehicle for multi-dimensional collaborations from spatial,social and ecological perspectives.Grounded in actor-network theory,the research constructs an analytical framework drawing on three distinct community garden projects in Beijing,each examined from a different stakeholder perspective to capture the full complexity of grassroots governance dynamics.The first case,analyzed from a resident's perspective,reveals the spatial production mechanisms through which diverse actors including long-term residents,newcomers,property managers,and local authorities negotiate,contest,and co-construct the operational realities of community gardens.It highlights how spatial use,access rights,and maintenance responsibilities become sites of ongoing negotiation,exposing the tensions inherent in transforming publicly owned idle land into collectively governed green spaces.The second case,examined from an initiator's perspective,illustrates how community gardens serve as catalysts for cultivating new neighborhood relationships and promoting multi-centric interaction and social integration through composting of local generated food waste and organic waste.Through participatory governance processes,initiators demonstrate that gardens function not merely as physical spaces but as social infrastructures that bridge biological,generational,occupational,and cultural divides,thereby strengthening community cohesion and collective efficacy.The third case,explored from a facilitator's perspective,investigates flexible operating models emerging under"co-creation partnerships"between government agencies,urban planners with academic background,and community groups.It further examines the realistic impact of China's widespread aging trend on the long-term sustainability of grassroots community practices,raising critical questions about intergenerational participation,institutional memory,and the scalability of volunteer-driven maintenance models.The study identifies several persistent challenges facing community garden practices in contemporary Chinese cities.These include the over-reliance on single public space functions,where gardens serve primarily recreational or aesthetic purposes without deeper social or economic integration,insufficient and uneven resident participation that limits governance legitimacy,and an underdeveloped professional operation and maintenance market that constrains long-term sustainability.The conclusion emphasizes that,despite these challenges,community gardens remain an effective and versatile tool for achieving"people-oriented"urban renewal.They embody a governance logic that is bottom-up,adaptive,and ecologically embedded.Future policy directions should formally integrate community gardens into the institutional framework of urban renewal,explicitly clarify their attributes as community co-construction projects,grant communities greater decision-making autonomy,and expand the value creation and sharing mechanisms for their social and environmental functions.By doing so,policymakers can unleash the synergistic benefits of community gardens in promoting social inclusion,environmental improvement,and community economic vitality,ultimately advancing the broader goals of China's urban regeneration agenda.
