A Study on the Effect of High-Speed Railway on Economic Growth of Beijing-Tianjin-Hebei Urban Agglomeration

In order to measure the value of high-speed railway in the development of Beijing-Tianjin-Hebei urban agglomeration and provide empirical support for the rationality of “eight horizontal and eight vertical” planning, based on the impact mechanism of high-speed railway on economic growth, this paper uses the data of 13 prefecture level cities in Beijing-Tianjin-Hebei urban agglomeration from 2009 to 2017 to quantitatively study the economy of Beijing-Tianjin-Hebei urban agglomeration triggered by high-speed railway Growth effect. The empirical results show that the overall effect of high-speed railway on economic growth of Beijing- Tianjin-Hebei urban agglomeration is 0.545 in the past two years, which is a large positive effect. The highspeed railway can not only directly stimulate the economic growth of Beijing-Tianjin-Hebei urban agglomeration by expanding the scale of capital investment, but also indirectly promote the economic growth of Beijing Tianjin Hebei urban agglomeration by promoting the development of system, technology, labor force and industrial structure, which proves the value of high-speed railway. Finally, according to the empirical results, it provides reasonable feasible suggestions to the relevant government departments
