Research on the Impact of Chengdu-Chongqing High-Speed Railway on Tourism Economic Connection of Cities Along the Line

As an important part of the tourism industry, tourism transportation plays a vital role in the development of tourism.By constructing an accessibility model and a tourism economic connection model, the article compares and analyzes the changes in tourism transportation accessibility and tourism economic connections of the cities along the line before and after the opening of the high-speed rail.The results show that the high-speed rail shortens the time and space between cities along the line distance significantly improves the accessibility of tourist traffic in the areas along the route, but the change rate of tourist traffic accessibility is uneven in spatial distribution.The accessibility improvement rate of the first and last cities is the lowest, and the middle of the route, the city's accessibility improvement rate is relatively high; the intensity of tourism economic linkages in the cities along the high-speed rail line has generally increased, but due to the effect of distance attenuation, the growth rate of the tourism economic linkage strength between the site cities is not the same; the total amount of economic contacts has shown a growth trend of varying magnitudes, and its balance has improved.
