With the acceleration of urbanization, the service system of urban communities plays an increasingly crucial role in enhancing residents’ quality of life and promoting sustainable urban development. This study, based on social embeddedness theory, constructs an analytical framework from four dimensions: structural embeddedness, relational embeddedness, functional embeddedness, and cognitive embeddedness. Using S Street’s pilot community as an example, this study delves into the operational logic, main challenges, and optimization paths of embedded service models in urban communities. The research reveals that this model faces issues such as insufficient resource integration, coordination difficulties, weak trust, and imprecise demand response. Therefore, it proposes measures such as strengthening party organization leadership, promoting multi-subject collaboration, optimizing resource allocation, and disseminating value concepts to provide theoretical and practical references for modernizing grassroots governance.
