The integrated development of rural industries is an important pathway to achieving rural revitalization and agricultural and rural modernization, with the digital economy empowering this integrated development of rural industries.Firstly, based on a summary of the connotation and characteristics of industrial integration, the theoretical mechanism of how the digital economy empowers the integration of rural industries is analyzed.Secondly, through case studies of e-commerce development in Dangshan County, Anhui Province, Cao County, Shandong Province, and Dayu County, Jiangxi Province, this paper analyzes the practical models of how the rural digital economy empowers the integration of rural industries through four mechanisms: digital production, industrial chain optimization, market expansion, and collaborative services. It summarizes the remarkable achievements of rural e-commerce in empowering the integrated development of rural industries from the perspectives of industrial integration pathways, talent cultivation models, and rural governance structures. Furthermore, it analyzes the challenges faced by rural e-commerce development from the angles of industry, market environment, and farmer participants, including insufficient industrial chain collaboration and weak interest linkage mechanisms among participants, bottlenecks in infrastructure construction and hindrances to the mutual flow of elements, as well as low digital literacy levels and poor risk resistance capabilities.Lastly, from a "three-in-one" perspective, this paper proposes the implementation path for the modernization of agriculture, rural areas, and farmers in China under the background of the digital economy.The research conclusions can provide decision-making reference for fully leveraging the digital economy to empower the integrated development of rural industries and promote the modernization of agriculture and rural areas in the context of rural revitalization.
