Abstract Innovation is the driving force of economic structure transformation and high-quality development, and transportation infrastructure construction plays an important supporting role in it. Based on the panel data of 41 cities at prefecture level and above in the Yangtze River Delta in 2007 and 2018, this paper uses the time-varying DID model to analyze the impact of the opening of high-speed rail on the level of urban innovation from the perspective of heterogeneous borrowing scale. First, the opening of high-speed rail has significantly improved the level of urban innovation. From the spatial dimension, the opening of high-speed rail has improved the innovation level of big cities, but it has no significant effect on the innovation level of small cities. Second, after the opening of the high-speed railway, its interaction with borrowed-performance inhibits the innovation level of the city, and its interaction with borrowed-function promotes the improvement of the innovation level of the city. Third, for large cities, the interaction between high-speed rail opening and borrowed-performance and borrowed-function has improved the urban innovation level. For small cities, the interaction between high-speed rail opening and borrowed-performance has no significant impact on the urbaninnovation level. The interaction between high-speed rail opening and borrowed-function has improved the urban innovation level.
