The Impact of High-Speed Railway Opening on Regional Economic Growth: The Case of the Wuhan–Guangzhou High-Speed Railway Line

With the advent of “ear high-speed railways”, space–time distance between cities has drastically decreased. The opening railways not only increased factor-flow speed across regions, but also reduced cost factor movement. However, there is some controversy about whether can be used to promote regional economic growth. Wuhan–Guangzhou railway earliest section Beijing–Guangzhou railway, and it was first in China with a real 350 km per hour. spawned three-hour circle south China, injected new vitality into social development along line, had an important impact on accelerating interoperability integration. Taking this account, paper took as case study. Firstly, theory system dynamics analyze mechanism Secondly, accessibility model difference-in-differences (DID) explore Finally, basis analysis previous mechanism, growth discussed. results study show following: (1) Since line grown by more than 60%. (2) promoted growth, mainly through influence “increasing total cargo volume”. This scientifically quantitatively analyzed rail taking example for empirical analysis, further summarized construction achievements provides reference experience planning railways.
