The work aims to propose a design strategy for the digitalization of bamboo weaving craft in southwest China from the perspective of design, to realize the innovative design and application of bamboo weaving craft through "art design + digital platform" and to promote the protection, inheritance, dissemination and innovation of traditional bamboo weaving craft. Based on the study about the current development of traditional bamboo weaving craft in southwest China, the bamboo weaving craft was sorted out and classified and the derivative design was carried out to the craft characteristics. A database platform was built for bamboo weaving craft in a dematerialised form, and then the feasibility of digital design strategy of bamboo weaving craft was verified through concrete design practice while innovative application of bamboo weaving craft was realized. Through research, a database was built for the bamboo weaving craft in southwest China, which effectively promoted the design output and practical application of bamboo weaving craft in southwest China and broadened the scope of application of bamboo weaving craft. The combination of design and technology enables the local innovative design and online promotion and dissemination of traditional crafts, and the diversified means promote the creative transformation and innovative development of traditional crafts, thus better contributing to rural revitalization.
