At present, the digital economy has become an important driving force for promoting Chinese-style modernization. As an important part of the new quality productivity, the digital economy can accelerate the reform of rural productivity, promote rural industry to achieve multiple goals such as chain extension, chain supplement and strong chain, so as to meet the needs of rural business entities to maximize the interests. Liangshan Prefecture focuses on the production end, sales end and management end of rural industry, and comprehensively promotes the digital transformation of rural industry, but it faces problems such as weak infrastructure, lack of funds, shortage of talents, imperfect supervision system, and dispersion of resource elements. In view of the above development difficulties, optimization measures are proposed from five aspects: strengthening the construction of rural digital infrastructure, increasing financial investment, improving the talent cultivation mechanism, improving the supervision and management system of e-commerce, and innovating the accumulation of resource elements, aiming at actively exploring the digital transformation and revitalization of rural industries in Liangshan Prefecture.
