High-speed rail Accessibility and Innovation Spillover in Cities Along the Route Based on a Spatial Dubin Model

Based on the panel data of 247 prefecture-level and above cities in China from 2006 to 2016, this paper establishes a spatial Dubin model (SDM) to study the spatial spillover effect and mechanism of the improvement of inter-city accessibility caused by high-speed rail on urban innovation capabilities. The study found that the improved accessibility of high-speed rail improves the city's innovation...
