The enhancement and improvement of China's high-speed rail network plays a crucial role in promoting sustainable economic growth in the region. By utilizing "new nighttime light data" in China's Yangtze River Delta from 2003 to 2018, this paper investigates the impact of HSR on economic growth using a multiperiod difference-in-differences (DID) model. The operations of high-speed rail have a significant and positive impact on economic growth, which often becomes more apparent with a certain time delay. The operations of high-speed rail have a significant positive impact on the development of large, mega, and super-cities, with this impact becoming more pronounced as the size of the city increases. Furthermore, high-speed rail operations have a significant influence on the economic growth of cities that largely rely on secondary and tertiary industries, in contrast to the primary industry. The promotion of economic growth by high-speed rail is primarily achieved through three transmission channels: low carbon emissions, labor force agglomeration, and innovation. Over time, high-speed rail will progressively reduce economic disparities between regions and facilitate a trend towards regional economic coordination or convergence. This study makes a valuable contribution to the exploration of pathways towards achieving economic growth.
中国高速铁路网的完善和拓展对促进该地区的可持续经济增长发挥了关键作用。本文利用中国长三角地区 2003 年至 2018 年的“新夜间灯光数据”，采用多期双重差分（DID）模型研究了高速铁路对经济增长的影响。高速铁路的运营对经济增长具有显著的正向影响，这种影响往往随着一定的时滞而变得更加明显。高速铁路的运营对大、特大城市和超大城市的发展具有显著的正向影响，而且随着城市规模的扩大，这种影响变得更加显著。此外，高速铁路的运营对主要依赖第二产业和第三产业的城市的经济增长具有显著影响，而对第一产业则没有显著影响。高速铁路对经济增长的促进主要通过三种传导渠道实现：低碳排放、劳动力集聚和创新。随着时间的推移，高速铁路将逐步缩小地区间的经济差距，促进区域经济协调或趋同。本研究为探索实现经济增长的途径做出了有价值的贡献。
