The development of e⁃commerce propels rural industries to transform from traditional, decentralised production to a modern market system with the upgraded value chain.This study , systematically explores mechanisms and practical pathways for rural e⁃commerce empowering rural industrial revitalization. From industry chain perspective, it analyzes the internal logic of rural e⁃commerce promoting industrial upgrading through data⁃driven approaches, market linkages, and digital transformation across pre⁃production, production, and post⁃production stages. By examining case studies from Suichang in Zhejiang, Tongyu in Jilin and Wugong in Shaanxi, three typical development models are summarized: the " integrated service provider⁃driven model " ,the " origin⁃based brand direct supply model " and the " regional distribution hub model ". In response to current challenges such as weak infrastructure, shortage of skilled professionals, fragmented industrial systems, and an imperfect legal environment faced by rural e⁃commerce, systematic optimization strategies are proposed across five dimensions withthe aim of providing references for deepening the application of rural e⁃commerce and promoting high⁃quality development in rural industries.
