RESUMO
With the accelerating process of aging, the burden of elderly care in China is increasing dramatically. However, the current care models were difficult to meet the multi-level and diversified needs of the elderly. Time banking mutual care model is proposed as an important auxiliary model. Since the elderly in urban communities are the major participants of time banking mutual care model, understanding their willingness to participate is very important for the effective implementation and sustainable development of time banking mutual care model. This paper summarizes the research progress and the major influencing factors of the willingness of the elderly to participate in time banking mutual care model, in order to provide theoretical support for alleviating the increasingly severe burden of elderly care in China and realizing active aging.
