本文回顾了中国的高速铁路网的历史演变，对可达性的改善进行了评估，并在考虑到区域异质性的情况下，分析了可达性改善与区域经济生产率的关系。考虑了三个可达性指标：到所有地级地区的平均旅行时间(ATT)、到重要城市的平均旅行时间(ATI)和每天可到达的地级地区。这些指标被用来量化2007年至2012年和2012年至2018年两个时期高铁网络的发展情况。首先，研究结果表明，在第一阶段，东部地区的可达性指标改善最多，而在第二阶段，西部地区的可达性指标改善最明显。随后，我们分析了引入高铁对城市群经济生产率和非均衡性的影响。这些结果表明，随着高铁的发展，中国中部、成渝和贵州中部城市群的表现良好。然后使用带有面板数据的多变量回归来衡量区域经济生产率和改善可获得性之间的联系。结果表明，农业技术转移和技术创新的降低对中国不同地理尺度上的经济生产率有显著的正向贡献。此外，ATT对东北和中部地区的影响较大，而ATI对东北和西部地区的影响较大。
This paper reviews the historical evolution of China’s high-speed railway (HSR) network, evaluates improvements in accessibility, and analyzes the associations of improved accessibility with regional economic productivity, given regional heterogeneity. Three accessibility indicators were considered: average travel time to all prefectural level regions (ATT), average travel time to important cities (ATI), and daily accessible prefectural level regions. These indicators were used to quantify the development of the HSR network during two periods, from 2007 to 2012 and 2012 to 2018. First, the results revealed that, in the first period, the accessibility indicators of the east region improved the most, whereas in the second period, the west significantly improved. We subsequently analyzed the economic productivity and -equilibrium of the urban agglomerations affected by introducing the HSR. Those results suggested that the Triangle of Central China, Chengdu-Chongqing, and Central Guizhou urban agglomerations performed well as the HSR developed. The linkages between regional economic productivity and accessibility improvement were then measured using a multivariable regression with panel data. The results showed that the reduction of ATT and ATI significantly positively contributed to economic productivity at different geographical scales in China. Furthermore, ATT had a larger effect in the northeast and central regions, whereas ATI had a larger effect on the northeast and west regions.
