[Purpose/significance] Starting from the analytical framework of actor-network theory, analyzing the datadriven model of smart elderly care around various scenarios will help us gain a deeper understanding of the infrastruc⁃ture of data-driven smart elderly care services and master its data-driven strategy to continuously promote the develop⁃ment of smart elderly care. [Method/process] Based on the actor-network theory, combined with the data value chain model and the concept of service scenario, the basic elements of data-driven smart elderly care services are analyzed.Starting from the three aspects of the physical space, interactive space and data space of the scenario, combined with lit⁃erature analysis, research interviews and domestic and foreign practical experience, the basic logic of data-driven smart elderly care services is deconstructed in the scenario. [Result/conclusion] The basic elements and translation
process of the smart elderly care actor network demonstrate the infrastructure and logical path of data-driven smart el⁃derly care services. Among them, the basic elements of the smart elderly care actor network emphasize multi-dimen⁃sional interactive service scenarios, structured data activities, and heterogeneously coupled actors as the infrastructure of data-driven smart elderly care services; the translation process of the smart elderly care actor network focuses on the logical path of data-driven smart elderly care services, with the purpose of industry docking, platform empowerment,and data efficiency enhancement, centering on service integrators, service providers, service demanders, and the data collection, organization, circulation, and utilization activities they participate in, through processes such as problem identification, benefit granting, subject absorption, and goal mobilization, data drives smart elderly care services.
