Study on the Spatial Effect of High-Speed Railway Network on Urban Economy under the Perspective of High-Quality Development:Taking the Yangtze River Economic Belt as an Example
The construction and improvement of high-speed railway network can greatly shorten the geographical distance between cities and help optimize the urban spatial structure.Based on the data of 106 prefecture-level cities in the Yangtze River Economic Belt from 2008 to 2020,the level of high-quality development of urban economy and the level of high-speed railway network are measured,and two-way fixed static and dynamic spatial Durbin models are chosen to test the spatial effect of high-speed railway network on urban economic development.The study shows the following.(1)The improvement of the high-speed railway network helps to improve the quality of economic development in the city,but it may have a certain inhibiting effect on the economic development of the neighbouring cities.(2)The spillover effect of HSR network on neighbouring cities varies from region to region.Among them,it has a more significant inhibitory effect on the high-quality development of neighbouring cities'economy in the middle reaches of the Yangtze River.(3)The improvement of high-speed railway network may bring some inhibition to the development of city economy in the short term,but in the long term,this adjustment helps the city economy to achieve high-quality development.
