The impact of high-speed rail on the urban economy

High-Speed Rail (HSR), characterized by train speeds exceeding 200 kilometers per hour, has emerged as a transformative mode of transportation, offering efficient intercity and long-distance travel. In recent years, China has developed the world's most extensive HSR network, raising important questions about its broader economic implications. This study investigates the impact of HSR construction and operation on regional economic development in China, with a particular focus on urban and peri-urban areas. Using qualitative case analysis, three representative railway linesthe HanYi Railway, YiWan Railway, and BeijingZhangjiakou High-speed Railwayare examined to explore how HSR influences local economies, connectivity, and industrial transformation. The findings suggest that HSR significantly enhances regional integration, improves accessibility in underdeveloped areas, and contributes to the emergence of new economic dynamics, thereby playing a strategic role in shaping China's spatial and economic landscape.
