Under the background of digital economy and rural revitalization, this study examines how e-commerce drives the spatial transformation and development of intangible cultural heritage villages in Yunnan Province. Drawing on case studies of Xinfa Village and Sanjie Town, we employ a mixed-methods approach combining policy analysis, field observations, and interviews with local stakeholders to reconstruct material, cultural, and social spaces. Our findings reveal that e-commerce platforms and live-streaming technologies have reshaped traditional residences into multifunctional compounds, enhanced cultural capital through branded IP and tourism integration, and reconfigured social networks by empowering younger generations in digital entrepreneurship. Quantitative indicators show a 30 % year-on-year increase in silverware livestream sales and a 15–20 % premium on embroidered products. We conclude that while e-commerce stimulates economic growth and cultural inheritance, sustainable governance frameworks and equitable benefit distribution are essential to address emerging challenges and ensure long-term vitality.
