青年发展型城市充分践行青年优先发展理念，是推动青年发展和城市发展相互促进、良性互动的一种城市发展模式。城市公共服务精准供给是促进青年发展型城市建设的重要抓手和实现方式，有助于满足青年日益增长的多样化、多层次发展需求，城市公共服务供给的类型选择、生产模式及供给方式直接影响着青年发展型城市的建设效果。本文在青年发展型城市的建设背景下，结合无缝隙政府理论和共同理论，分析青年发展型城市公共服务精准供给目标、内涵特征以及实现路径，系统性构建了青年发展型城市公共服务精准供给机制。选取成都市为案例城市，采用资料查阅、问卷调研及访谈调查等方式，从需求识别、方案设计、内容生产、服务供给及效果评估五个方面对成都市相关公共服务供给工作进行了详细讨论。重点分析了以青年群体为主的城市多元主体如何共同参与不同类型的公共服务生产与供给，分别讨论了成都市城市公共服务共同生产的前置条件、合作动机、收益分析和激励机制，以及服务供给中的供给主体、供给内容、供给平台和供给技术。通过案例分析及调研，发现成都市青年公共服务供给还未达到完全平衡、城市公共服务共同生产能力仍待加强，且尚未形成城市公共服务精准供给整体机制。针对以上问题，提出青年发展型城市应当重视青年公共服务需求，提高需求识别能力，因地制宜建立城市公共服务精准供给多方联动机制，加强公共服务供给相关规划，促进精准供给整体机制建设等对策建议。

Youth-development-oriented cities fully implement the concept of youth priority development, which is an urban development model that promotes mutual promotion and positive interaction between youth and urban development. The precise supply of urban public services is an important starting point and realization method for promoting the construction of a youth-development-oriented city, helping to meet the increasingly diverse and multi-level development needs of youth. The type selection, production mode, and supply mode of urban public services directly affect the construction effect of a youth-development-oriented city.In the context of building a youth-development-oriented city, this paper combines seamless government theory and common theory to analyze the precise supply goals, connotation characteristics, and implementation paths of public services in youth-development-oriented cities, and systematically constructs a precise supply mechanism for public services in youth-development-oriented cities. Taking Chengdu as a case city, this paper discusses in detail the relevant public service supply work in Chengdu from five aspects: demand identification, scheme design, content production, service supply, and effect evaluation through data review, questionnaire survey, and interview survey. The focus is on analyzing how diverse urban entities, mainly youth groups, can participate in different types of public service production and supply, respectively discussing the preconditions, cooperative motivations, revenue analysis, and incentive mechanisms for urban public service co-production in Chengdu, as well as the supply subject, supply content, supply platform, and supply technology in service supply.Through case analysis and investigation, it is found that the supply of youth public services in Chengdu has not yet reached a complete balance, the co-production capacity of urban public services still needs to be strengthened, and the overall mechanism for precise supply of urban public services has not yet been formed. In response to the above issues, it is proposed that youth-development-oriented cities should attach importance to the needs of youth public services, improve their ability to identify needs, establish a multi-party linkage mechanism for accurate supply of urban public services based on local conditions, strengthen relevant planning for public service supply, and promote the establishment of an overall mechanism for accurate supply.
