The increasingly serious situation of population aging has promoted the transformation of the traditional elderly care model to the“smart elderly care”model. The article compares the development history and current situation of the“smart elderly care”model in Zhalangkou Street，Hangzhou. This article adopts the multi - layer nested application of social network，advocacy and social integration theories to explain the effectiveness and dilemma of the“smart elderly care”model in practice. It refines the core factors of this model in Zhalangkou Street to achieve the efficiency of health care integration，equalization of public services and digital empowerment innovation. The study also analyses the causes of inadequate resource allocation，lack of service awareness and difficulties in digital transformation. We propose countermeasures for systematic integration of resources，diversified promotion of services and digital precision with the expectation of providing a reference for developing and implementing digitally empowered community elderly care services.
