As a national intangible cultural heritage， Qingshen bamboo weaving has faced significant challenges in recent years due to accelerated industrialization and the widespread adoption of plastic substitutes， leading to a decline in its market position. The industry is now at a critical juncture， requiring urgent transformation and upgrading. Based on CCR model， BCC model and Malmquist index in data envelopment analysis （ DEA ） theory， static analysis and dynamic measurement of input-output data of 9 Qingshen bamboo weaving enterprises from 2021 to 2023 were carried out. The results show that technological innovation and market adaptability are essential for enhancing productivity， while optimizing scale efficiency is crucial for sustaining and improving overall industry benefits. Based on these insights， the author proposes six key recommendations： strengthening brand building and expanding into international markets； broadening sales channels and promoting integration and collaborative development of the industrial chain； enhancing technological innovation and R&D investment； improving design capabilities； facilitating industrial integration， establishing industrial alliances， and focusing on environmental protection and sustainable development. These strategies offer valuable guidance for the sustainable development of the Qingshen bamboo weaving industry and contribute to broader rural revitalization efforts.
