Abstract: Against the backdrop of deep integration between digital intelligence and aging, promoting the high-quality development of smart and healthy elderly care products is a crucial measure to achieve the digital transformation of elderly care, foster the silver economy, and enhance the quality of life for the elderly. Based on the three phases of panel data from the China Aging Social Tracking Survey (2018-2023), this study empirically examines the impact of smart and healthy elderly care products on older adults' aging age identity. The findings reveal that such products can significantly improve the aging age identity among the elderly, with more pronounced effects among middle-aged and low-aged groups, women, urban residents, and those with better self-rated health. The mediation effect tests indicate that smart and healthy elderly care products can indirectly promote the formation of the positive aging age identity by enhancing individuals' self-efficacy and fostering social participation. Further analysis shows that health management and elderly care monitoring smart products play a significant positive role in shaping positive aging age identity, with a clear“cumulative effect”—the more products used, the more positive the aging age identity of the elderly. Therefore, in advancing the demonstration and pilot projects of smart and healthy elderly care, efforts should be coordinated on both supply and demand sides. While promoting the construction of the supply-side industrial chain and improving product quality, it is essential to strengthen the elderly's awareness of product usage and digital literacy on the demand side.
