| Under the background of Liaoning province expanding its opening-up pattern and industrial transformation.Improving the conditions of high-speed transportation and improving the accessibility of high-speed railway,highway and airport are of great significance for improving the overall transportation conditions.The "corridor function" of transportation can promote the development of tourism economy along Liaoning Province's transportation line.The improvement of high-speed transportation can greatly save the travel time of tourists,shorten the shortest travel time of the two places,improve the way of travel of tourists,and promote the logistics and flow of people between regions.So as to promote the development of the whole regional tourism industry.In this study,14 prefecture-level cities in Liaoning Province were taken as the research objects,and 2008,2012 and 2016 were taken as the research time nodes,and the shortest travel time of railway trains in Liaoning Province was taken as the shortest distance between the two cities.Referring to the measurement model of high-speed traffic superiority,this paper studies the change of high-speed traffic superiority in Liaoning Province.Firstly,the construction of high-speed railway plays an important role in improving the overall high-speed traffic superiority of 14 cities in Liaoning Province,but the increase range varies in different time periods.In 2012,due to the opening of Harbin-Dalian Railway,the railway runs through the north and south of Liaoning Province,which greatly improves the urban traffic superiority along the railway.After the opening of Shendangao in 2016,the urban high-speed traffic advantage along Shendan high-speed railway has been greatly improved,especially in Dandong.Due to the difference of geographical location,the shortest distance from Shenyang,the central city of Liaoning Province,is centered on Shenyang,and gradually decreases to the periphery.The advantage degree of high-speed traffic forms a "center-periphery" shape in the spatial pattern.Secondly,the evaluation of the level of tourism economic development is to select six classical indicators,calculate the comprehensive scores of six indicators of 14 prefecture-level cities,and comprehensively evaluate the level of tourism development of prefecture-level cities.Influenced by the amount of resources and geographical position,the tourism development level of Dalian has formed a dual-core and planar distribution pattern withShenyang and Dalian as the core.The tourism development level of Dalian has more advantages.Among the six indicators,the number of domestic tourists and domestic tourism income are decreasing year by year.Therefore,we should attach importance to the development of the domestic market,expand the domestic market share,and broaden channels to attract tourists to the market.Thirdly,the coordination degree between the advantage degree of high-speed transportation and the level of tourism development in Liaoning Province is in the middle-low and low-level stage as a whole.The coordination level of Shenyang and Dalian is slightly higher than that of other cities,reaching the middle level.Other cities near the central city of Shenyang have the lowest level of coordination,and the peripheral cities have the lowest level of coordination,which belongs to the low level of coordination.The development level of high-speed transportation and tourism in Liaoning Province presents a "center-periphery" circle spatial distribution structure as a whole,and Dalian belongs to a unipolar high-value region.Finally,the paper puts forward Suggestions on the development and construction of liaoning province from the aspects of the construction of sub-area,the promotion of regional coordination,the adjustment of industrial structure,the development of tertiary industry and the expansion of the level of opening to the outside world.It provides theoretical guidance for the coordinated development of high-speed traffic and tourism in liaoning province. |
