Abstract
The demographic transition toward an aging society presents unprecedented challenges for traditional community-based elderly care systems, necessitating a paradigm shift toward digital transformation. This paper explores the strategic integration of digital technologies—ranging from Internet of Things sensors to telehealth platforms—into community care frameworks. Utilizing a System Dynamics modeling approach, we analyze the complex, non linear feedback loops inherent in care delivery, technology adoption, and resource allocation. The study constructs a simulation model to evaluate the long-term impact of various digital strategies on service quality, operational efficiency, and financial sustainability. Our findings reveal that while technology implementation offers significant potential for alleviating labor shortages, its success is heavily contingent upon concurrent investments in digital literacy training for the elderly and the interoperability of information systems. The simulation results suggest that a balanced allocation of resources between hardware infrastructure and user education yields the highest sustained improvement in care capacity. This research contributes to the domain of social systems engineering by providing a quantitative decision-support tool for policymakers and care administrators, highlighting the critical importance of a holistic approach to digitalization in the silver economy.
