Abstract
The mutual aid elderly care model is important to solve the world population's current aging problem. However, although mutual aid elderly care has been developing in China for more than 20 years, there is still a lack of a systematic way to participate in mutual aid elderly care services, which has led to a slow development of mutual aid elderly care. Therefore, in order to promote the development of mutual aid elderly care and the transition of social elderly care towards sustainability, this study analyzes the actual elderly care service needs and proposes new design strategies for mutual aid elderly care service platforms. In this study, first, the actual elderly care needs were obtained through interview methods and offline questionnaire surveys. The results showed that the elderly have a high demand for health, daily life, entertainment, and spiritual needs, which can be used to establish a comprehensive Kano model. Based on the priority of the needs hierarchy, mutual aid elderly care resources can be allocated rationally. For example, when applying the research results to the design of mutual aid elderly care service platforms, the "Must-be quality" is first satisfied, followed by the "One-dimensional quality" and the "Attractive quality" according to the actual situation. Furthermore, the mutual aid elderly care service platform is divided into a basic version and a professional version to promote the actual needs of different groups of elderly people. In conclusion, the study aims to promote the development of mutual aid elderly care and the transition of social elderly care towards sustainability. The research value of this study lies in its potential to alleviate the slow development of the current mutual aid elderly care model in China and provide a reference for solving the problem of global aging population.
