The spatial impact of high-speed rail on firm performance: The role of proximity to urban cores?

This paper examines the spatial impact of high-speed rail (HSR) connection on firm performance in China at the micro level using a unique administrative dataset. Connected firms benefit from agglomeration economies and improved market access, but the redistribution of production inputs towards urban cores may have a negative impact on firms in peripheral regions. If these opposing forces are both subject to spatial decay but at different rates, proximity to urban cores could play a crucial role in determining the overall effects of HSR connection on firms. We find that connected firms located farther from urban cores benefit the most, indicating a steeper spatial decay in the redistribution effect relative to the agglomeration effect. This research enhances our understanding of the micro-level spatial impact of HSR on regional development.
