Study on the Influence of High-speed Railway on: Regional Economic Development——Taking Harbin-Dalian High-speed Railway as an Example

With the rapid development of the Chinese economy, road transportation has become one of the main factors that restrict the development of the high-speed and high-quality Chinese economy. At present, China is vigorously promoting the development of the high-speed railway to promote regional economic development. However, due to the geographical location and uneven economic development levels of various regions, the impact on various regions after the opening of the high-speed railway is different. Based on the large high-speed railway as an example, through the grey prediction model, by the high iron to produce a direct impact on regional accessibility as the explained variable, the introduction of other control variables to establish the regression equation, the per capita GDP, industrial structure and urbanization rate to explain, to predict the development trend of the future in the absence of any high-speed and compared with the actual situation. In general, Harbin-Dalian high-speed railway plays a positive role in improving regional accessibility, per capita GDP, and urbanization rate, but it has little significance in improving the industrial structure along the route. Although the research example of the Harbin-Dalian high-speed railway is different from the expected positive effect of the high-speed railway, it is necessary to study the influence mechanism of the high-speed railway on more and different types of the regional economy to better understand the significance of high-speed railway for the regional economy.
