Effects from Expanding High-Speed Railway Network on Regional Accessibility and Economic Productivity in China

This paper reviews the historical evolution of China’s High-Speed Railway (HSR) network, evaluates improvements in accessibility, and analyses 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 (DA4). These indicators are used to quantify the development of the HSR network during two periods, from 2007-2012 and 2012-2018. First, the results unveiled that in the first period, the accessibility indicators of the east region were improved the most while in the second period, the west significantly improved. Next, the authors analyzed the economic productivity and economic equilibrium of urban agglomerations affected by introducing HSR. The results suggested that the Triangle of Central China, Chengdu-Chongqing, and Central Guizhou urban agglomerations performed well as the HSR developed. Then, the linkages between regional economic productivity and accessibility improvement were measured using a multivariable linear 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; and that the ATT had a larger effect in the northeast and central regions while the ATI had a larger effect on northeast and west regions.
