China's digital elderly friendly policies have gone through three stages of development: exploratory initiation (2015-2019), rapid growth (2020-2021), and stable deepening (2022 to present). Through text analysis of 51 digital aging policies issued by the central and ministerial departments in China, it can be perceived that the logic of China's digital aging policies has achieved iterative upgrades from basic guarantees to technological empowerment, and then to ecological construction. The allocation of policy tools presents the characteristics of "heavy supply, weak environment, and light demand", and the effectiveness of institutional incentives and market traction has not been fully released. The participating entities form a non-equilibrium collaborative network led by the government, and the collaborative linkage mechanism among multiple entities still needs to be improved. Entering the period of the 15th Five Year Plan, a systematic construction of digital elderly friendly policies can be carried out from four dimensions: top-level design of rule of law, balanced policy tools, ecological coordination of subjects, and long-term governance guarantee.
