交通可达性与旅游经济联系空间关系研究——以大西高铁为例

Study on the Spatial Relationship between Traffic Accessibility and Tourism Economic Linkage: Taking Daxi High-speed Railway as an Example

在中国高铁发展日益受到关注的背景下,以大西高铁为例,使用城市间的矢量路网、高铁站点及各城市旅游收入、旅游人数等数据,运用加权平均旅行时间和引力模型,对大西高铁沿线及周边城市在高铁开通前后的交通可达性和旅游经济联系进行分析,并使用耦合协调度模型对两者进行耦合协调分析。结果表明:大西高铁的开通显著提升了各城市的可达性水平,但提升程度不均衡,致使研究区交通可达性的空间公平性降低;区域内旅游经济联系强度显著增加,且沿线城市间旅游经济联系提升较为明显,各城市的旅游经济联系总量均大幅提升;高铁的开通对高铁途经城市的交通可达性与旅游经济联系的协同发展起着一定的促进作用,但对高铁未途经城市的促进作用并不显著,甚至出现了协调度降低的情况。

Against the backdrop of the growing interest in China’s high-speed railway development,this study takes the Daxi high-speed railway as an example.Using data on the inter-city vector road network,high-speed railway stations,and the tourism revenue and tourism numbers of each city,weighted average travel time and gravity models are used to analyze the transport accessibility and tourism economic linkages of cities along and around the Daxi high-speed railway.The coupling coordination model is also used to analyze the coupling coordination between the two.The results show that:The opening of the Daxi high-speed railway has significantly improved the accessibility level of each city,but the degree of improvement is uneven across cities,resulting in a reduction in the spatial equity of transport accessibility in the study area;The intensity of tourism economic linkages within the region and the total tourism economic linkages of each city have increased significantly,and the spatial equilibrium of tourism economic linkages has been improved;The opening of the high-speed railway has contributed to the synergistic development of transport accessibility and tourism economic linkages in cities passing through the high-speed railway,while the contribution to cities not passing through the railway is not significant,and there is even a reduction in the degree of coordination.
