Abstract: Purpose/Significance The research aims to improve the efficiency of the integration of smart elderly care industry chain and secure the healthy development of the industry. Design/Methodology This paper studies the influencing factors of the integration of smart elderly care industry chain, builds a “triple function relationship”, and uses the structural equation model (SEM) to analyze factors affecting the integration of smart elderly care industry chain. Findings/Conclusions Research results show that (1) the elderly care environment, the demand structure of the elderly, and smart elderly care service system are positively correlated to the development of the industry; (2) elderly care operation and smart elderly care system are positively correlated to the effect of service feedback; (3) the development of smart elderly care industry is positively correlated to the effect of service feedback; (4) the service model of smart elderly care industry, the management model of smart elderly care enterprises, and the demand tendency of the elderly have restricted the integration of smart elderly care industry chain to a certain extent. Based on that, this paper puts forward three suggestions: (1) creating a comprehensive service model of smart elderly care industry and building a triple “industry chain integration” system; (2) improving the management model of smart elderly care enterprises to form the chain that incorporates “target, platform, model and product”; (3) building a model of changes in the (mental and physical) needs of the elderly, and clarifying their demand tendency at different ages for smart elderly care service.
