丝绸之路城市群旅游经济联系的网络演化与协同发展研究

空间网络化发展是丝绸之路城市群旅游发展的特征之一，本文以2009年、2014年及2019年为时间截面，运用修正的引力模型和社会网络分析，对丝绸之路城市群27个城市旅游经济联系的空间网络结构演化进行分析。研究表明:（1）丝绸之路城市群旅游经济联系强度大幅度提升，但存在严重的不均衡性；（2）城市群旅游网络结构趋于成熟，网络节点的中心性存在差异；（3）网络中核心区由东向西不断扩大；（4）城市群中存在极为相似的子群，并处于动态变化之中。基于此，结合各城市的资源现状与交通等情况，从点、线、面三个角度构建了“三级三轴四片区”的发展模式，以实现丝绸之路城市群旅游的协同发展。

Study on the Evolution of Network Structure and Coordinated Development of Tourism Economic Links in the Urban Agglomeration along the Silk Road

The development of spatial network is one of the characteristics of tourism development in the Urban agglomeration of the Silk Road. Taking 2009, 2014 and 2019 as time sections, this thesis used the modified gravity model and social network analysis to analyze the evolution of spatial network structure of tourism economic links of 27 cities in the Silk Road urban agglomeration. The research results are as follows. First, the strength of tourism economic links in the Silk Road urban agglomeration has been greatly increased, but there is a serious imbalance. Second, the tourism network structure of urban agglomeration tends to mature, and there are differences in the centrality of network nodes. Third, the core area of the network is expanding from east to west. Finally, there are very similar subgroups in urban agglomeration, which are in dynamic change. Based on these results, the thesis combines the current situation of resources and traffic in each city and constructs a development model of “three-level, three-axis, and four-area” from three angles of point, line and area, so as to realize the coordinated development of the Silk Road urban agglomeration.
