Abstract：The digital transformation of service industries constitutes a critical driver of high-quality economic development in urban,serving as a key factor in enhancing innovation capacity and fostering new quality productive forces.Based on three sets of micro big data,this article constructs an evaluation index of digital technology innovation from the perspective of innovation chain.Using panel data of 283 cities from 2003 to 2022 in China,this paper empirically analyzes the impact of digital technology innovation on urban services.Results show that digital technology innovation significantly improve services through three mechanisms including innovation-driven,consumption upgrading and productivity enhancement.Heterogeneity reveals that digital technology innovation has stronger effects in the eastern region,central urban and innovation-pioneer cities.Furthermore,the impact of digital technology on producer services is more significant,and specifically the breadth of its adoption enhances low-producer services,while high-producer services derive greater value from the depth of its application.
