Research on the integration development model of “language + culture + tourism + older adults care” based on digital technology

This study empirically examines the effectiveness of integrating "language + culture + tourism + older adults care" services through digital technology to address the challenges of population aging. Using public data from six Chinese cities (Shanghai, Hangzhou, Wuhan, Changsha, Chengdu, Xi'an) collected from June to August 2024, we constructed a Digital Integration Index (DII) and employed structural equation modeling and multiple regression analysis to evaluate integration effects. Results demonstrate that digital integration significantly improves older adults people's quality of life (effect size = 0.68), digital participation (0.74), and service satisfaction (0.71), with synergistic effects contributing approximately one-third of total effects. The integration model shows stronger effects for the 60-65 age group (0.82) and eastern cities (0.79), though central and western regions exhibit greater improvement magnitude. Key success factors include improved dialect recognition accuracy (68 to 89%) and age-friendly interface design. Cost-benefit analysis reveals a 24.3% reduction in per-user service costs post-integration. The study provides quantitative evidence for multi-domain service integration, offering an evidence-based framework for policy-making. Future research should extend observation periods and expand geographic coverage to validate long-term effects and rural applicability.
