【摘要】 青年拾荒者在“无废城市”建设背景下所参与的非正规就业空间实践是资源循环回收链条的衔接环节。基于社会空间理论、制度边缘理论，构建“空间挤压—空间共生”分析框架，运用民族志研究方法进行田野调查。研究发现，“无废城市”空间秩序正规化治理对青年拾荒者产生空间挤压效应，具体表现为工作空间的碎片化、技术工作准入门槛提高、价值忽视与身份污名化等三重挤压。物理空间、技术工具和符号意义三重空间挤压对应形成了防御型、依附型、创新型三类非正规就业空间再生产实践。面对物理空间挤压困境，城市青年拾荒者通过隐蔽化作业方式延续传统非正规分拣以实现“缝隙”空间维系；面对技术空间挤压困境，他们主动嵌入并依附于城市垃圾处理的正规化网络以获取技术支持；面对符号空间挤压困境，他们应用数字化工具使其生态价值显性化并获得身份认可。构建城市青年拾荒者非正规就业空间再生产的合理化路径，需根据三类再生产实践对其采取针对性措施，通过制度规范、经济支持与社会赋能，促进防御型青年拾荒者融入社区互助空间、开展依附型青年拾荒者职业技能培训、提高创新型青年拾荒者劳动价值能见度，实现从非正规回收者到资源再生产的辅助者与“无废城市”共建者的身份转变。更多还原

【Abstract】 The informal employment practices of urban youth scavengers within the context of "zero-waste city" development serve as a crucial link in the resource recycling chain. Based on the theory of social space and the theory of institutional margins, this paper constructs an analytical framework of "spatial extrusion-spatial symbiosis", and uses ethnographic research methods to conduct field surveys. Findings reveal that the formalization of spatial governance under the "Zero-Waste City" initiative imposes spatial compression on young scavengers, which is manifested in the triple squeeze of fragmented work spaces, increased entry barriers to technical jobs, value neglect, and identity stigmatization.In response to the triple squeeze of physical space, technological tools, and symbolic meaning, they have developed three types of informal employment space reproduction practices: defensive, dependent, and innovative. Faced with the dilemma of physical space squeeze, young urban waste pickers continue traditional informal sorting through covert operations to maintain "gap" space; faced with the squeeze of technical space, they actively embed and attach themselves to the formalized network of urban waste treatment to obtain technical support; faced with the squeeze of symbolic space, they use digital tools to make their ecological value explicit and gain identity recognition.To construct rational pathways for reproducing informal employment spaces for urban youth scavengers, requires targeted support measures need to be taken based on three types of reproduction practices. Through institutional regulation, economic support, and social empowerment, this approach promotes the integration of defensive youth scavengers into community mutual-aid spaces, provides vocational skills training for dependent youth scavengers, and enhances the labor value visibility of innovative youth scavengers,and realize the identity transformation from informal recyclers to helpers of resource reproduction and co-builders of "waste-free cities".更多还原
