Abstract
BACKGROUND: In light of the accelerated growth of China's digital economy and the ongoing enlargement of the older adults population obsessed with chronic ailments, the ramifications of the digital divide on the quality of life of urban older adults with chronic diseases have emerged as a significant concern. This study seeks to elucidate the manner in which the digital divide influences the quality of life of urban older adults with chronic diseases. METHOD: This study employs the Chinese Older Adults Social Tracking Survey (CLASS2020) dataset and a multivariate ordinary least squares (OLS) regression model for statistical analysis. In this study, quality of life is employed as the dependent variable, while digital access and digital use of the digital divide are utilised as core explanatory variables. The pertinent indicators are weighted using the CRITIC weighting method to construct a composite indicator of quality of life and digital use. RESULT: Study findings show that digital access boosts urban older adults' quality of life with chronic conditions, but overuse could reduce it. Social support mediates this relationship, with formal support being most effective. Accessibility of community services and facilities have a negative moderating effect on this influence: they decrease the positive impact of digital access and reduce the negative effects of digital use. Notably, Accessibility of community services enhances quality of life by offering care and activities, showing a "replenishment" effect. It is suggested that the government promote the inclusion of smart older adults care through state subsidies and tax credits. CONCLUSION: This study highlights the importance of social support and community environment in improving the quality of life for older adults with chronic diseases in the digital economy. It suggests that policymakers should focus on reducing the digital divide and enhancing accessibility of community services to support these individuals. Additionally, the potential mental health issues arising from digital use should be recognized, requiring appropriate digital education and psychological support for older adults.
