Abstract：Accelerating the iteration,updating,and deepened application of green digital technology is a crucial initiative for China to build new competitive advantages for the future,carrying profound significance.This study takes 283 cities in China from 2007 to 2022 as research samples and employs a difference-in-differences(DID)model to empirically examine the impact of the new energy demonstration city construction pilot policy on urban green key digital technology innovation.The results indicate that the construction of new energy demonstration cities can enhance the level of green digital technology innovation in pilot areas.Mechanism tests show that the construction primarily drives leaps in green digital technology innovation by increasing science and technology expenditures,strengthening environmental regulations,and improving technology accessibility.Heterogeneity tests further reveal that the promotional effect of the pilot policy is more pronounced in cities with lower administrative levels,abundant human capital,and non-resource-based economic structures.This research provides policy insights for exploring breakthroughs in green key digital technologies in the context of the new digital era.
