Using a sample of Chinese A-share listed companies from 2008 to 2023, this study investigates the impact of digital-real industry technology integration on the expansion of firms’geographic boundaries. The results show that technological integration between digital and real industries significantly contributes to the expansion of firms’ geographical boundaries. Mechanism analysis reveals that the integration of digital-real industry technology promotes the expansion of firms’ geographic boundaries by mitigating information asymmetry, improving the quality of internal controls, enhancing agility and responsiveness, and improving the efficiency of production and operations. Heterogeneity analyses find that this positive effect is more pronounced among state-owned enterprises, large-scale firms, firms with experience in expansion, non-heavily polluting firms, and firms in the eastern region.
