Abstract： Using a combination of empirical methods including panel regression models，threshold effect models， mediation effect tests，and PVAR models，this study investigates the impact mechanisms of digital transformation and the national unified market on green innovation bubbles in China，and conducts stratified analysis based on diffrent regions，levels of digital economy development，and enterprise sizes.The results show that digital transformation significantly reduces regional green innovation bubbles， and the national unified market further enhances the negative effect of digital transformation through positive moderation.In addition，the national unified market exhibits a negative mediating efect in the process by which digital transformation influences green innovation bubbles.The negative effect of digital transformation is most pronounced in regions with low levels of digital economy development and among medium-sized high-tech enterprises.The findings indicate that promoting digital transformation and improving the construction of a national unified market contribute to optimizing resource allocation， enhancing innovation quality，and effectively curbing green innovation bubbles，thereby facilitating the sustainable development of green innovation.
