Abstract
Changes in intercity transport costs can reshape patterns of urban specialization and contribute to regional inequality. This paper explores the effects of high-speed rail (HSR) on regional disparity by examining the asymmetric impacts of HSR connections on urban specialization between core and peripheral cities. Leveraging a set of city-pair-level indicators capturing HSR connection and a difference-in-differences (DID) strategy with high-dimensional fixed effects, we find that HSR connections significantly intensity intercity specialization. Sectoral analysis reveals that HSR connections widen the employment gaps in the service sector between core and peripheral cities, while narrowing the gap in manufacturing employment. This suggests a siphoning effect in the service sector, where large cities increasingly attract employment from smaller neighbors. The effect is particularly pronounced among city pairs characterized by greater development gaps, geographic proximity, and divergent industrial structures. Additional evidence indicates that the service sector response is primarily driven by growth effects, whereas the manufacturing response reflects a redistribution of existing employment.
