Digital economy and aging population are two important characteristics of the Chinese modernization process. The process of population aging in China has entered a fast lane，and the consumption demand and service guarantee of the elderly groups have become an important concern of the society. Through interconnection，data，integration，transformation and innovation，digital technology can build a good information ecology of an aging society，effectively improve the efficiency of resource allocation，and drive the transformation and upgrading of traditional consumption to new consumption. The digital economy enables the consumption field of the aging society from both the demand side and the supply side. From the demand side，digital technology efficiently links upstream resources and downstream consumers，effectively solves the problem of information asymmetry in the consumption link，and improves market demand；from the supply side，the emergence of the platform model has greatly expanded the service radius of service providers，and created many new forms，new scenarios and new models of consumption with the integration of data and reality. We must have a deep understanding of social changes，firmly grasp the opportunities of the times，and actively explore the implementation path of digital economy enabling elderly social consumption from the four dimensions of “strengthening scientific and technological innovation，increasing government guidance，improving market mechanisms，and realizing digital governance”.
