Abstract: Studying the logic, mechanism, and path of promoting rural industrial structure adjustment through digital rural construction is conducive to promoting the digital transformation of rural industries. Currently, in the process of promoting the digital transformation of rural industries, digital rural areas use digital technology to adjust the scale of rural industrial development from the perspective of market demand, adjust the level of rural industrial development from the perspective of production technology, restructure the industrial chain of rural industries from the perspective of organization, and promote the integrated development of rural industries from the perspective of resource allocation. It continuously promotes the adjustment of rural industrial structure, making it more in line with the needs of socialized large-scale production and efficient resource allocation. However, there are still issues in promoting the adjustment of rural industrial structure in digital rural areas, such as prioritizing short-term market demand over long-term sustainable development, prioritizing the efficiency improvement brought by technological innovation over the coordinated development of light industries, and prolonging the heavy industry chain and the mutual support and integration between light industry chains. To scientifically promote the adjustment of rural industrial structure in digital rural areas, we must change our mindset and promote industrial structure adjustment in a systematic manner; Innovate ways to promote industrial structure adjustment in a holistic manner; Optimize allocation and promote industrial structure adjustment through the optimal utilization of resources. The construction of digital rural areas has greatly promoted the development of rural industries. In the chain from research and development, production to market sales, various industries are becoming increasingly closely connected and gradually developing towards the direction of large industries.
