In the new journey towards building a modern socialist country in an all-round way, the realization of common prosperity in rural areas has become an important issue for national development. This paper believes that as a new form of productivity, digital new quality productivity has the characteristics of deep technology integration and model innovation, efficiency leap and green sustainability, network collaboration and ecological construction capabilities, data insights and smart decision-making, flexible response and rapid iteration capabilities. At the theoretical, historical and practical levels, digital new quality productivity has become an important force in promoting common prosperity in rural areas, empowering rural common prosperity through mechanisms such as stimulating new momentum, the cultivation of new industries, the activation of new factors, and the leadership of new models. However, the application of digital new quality productivity in rural areas still faces key constraints such as lagging digital infrastructure construction, low digital literacy of farmers, and imperfect market mechanisms. Therefore, specific promotion paths have been proposed, including increasing investment in digital infrastructure, enhancing farmers' digital literacy, improving market mechanisms, enhancing governance capabilities, and bridging the digital divide, in order to provide theoretical support and practical guidance for the realization of common prosperity in rural areas.
