Abstract： The influence of high-speed railway on urban green technology innovation represents apivotal area of study within the broader research on the impact of high-speed railway on regional innovation.To investigate the effect of high-speed railwayon the“dual enhancement of quantity and quality”inurban green technology innovation，a multi-period Difference-in-Differences （DID） model was established.This model utilises panel data from 41 cities within the Yangtze River Deltaurban agglomeration spanning the years 2004 to 2019 to explore how the high-speed railway opening influences urban green technology innovation.The findings reveal that the introduction of high-speed railway significantly promotes the“dual enhancement of quantityand quality”in green technology innovation across the Yangtze River Delta cities.Mechanism analysis further indicates that high-speed railway impacts urban green technology innovation by bolstering economic agglomeration and venturecapital investment.Additionally，the effects of high-speed railwayopening exhibit heterogeneity in termsof city size and regional characteristics，with notable impacts observed in both large cities and smallto mediumsized cities.Specifically， the influence of high-speed railway is more pronounced in Jiangsu Province compared to Zhejiang and Anhui Provinces.This study systematically elucidates the relationship between the high-speed railway opening and the“dual enhancement of quantity and quality”in urban green technology innovation within the Yangtze River Delta region. The conclusions remain robust following rigorous stability tests.
