网络城市视角下的成渝城市群旅游经济空间网络特征

Spatial Network Characteristics of Tourism Economy in Chengdu-Chongqing Urban Agglomeration from the Perspective of Network-City

建立在网路城市理念的视角下,以成渝城市群16个地级市为研究案例,基于引力模型计算旅游经济联系度,利用社会网络理论与方法,借助Ucinet6.0软件构建旅游经济联系的网络空间结构,通过网络中心度、网络密度、网络族群等指标模型分析旅游经济空间结构特征,最终构建旅游地的空间等级体系和空间发展模式。结果表明:成渝城市群各城市的旅游经济联系强度存在差距较大的层级,并且基本形成“T形”轴加内部“C形”圈的空间结构。成渝城市群旅游经济网络整体的网络密度偏低,整体网络的各节点城市联系不高,中心度分析结果也表明区域旅游经济网络主要受到以成都、重庆作为核心节点的外向驱动作用,缺乏次级枢纽城市。旅游经济网络的内部出现凝聚子群,但凝聚子群的深度和广度不高。

From the perspective of network-city,this paper took 16 cities of Chengdu-Chongqing urban agglomeration as a case study,to calculate the connection degree of tourism economy based on gravity model,construct the network spatial structure of tourism economic connection with the help of Ucinet 6.0 software and by using social networks theory and methods,and analyse the structural characteristics of tourism economic space through network centrality,network density,network ethnic group and,etc.Finally,the spatial hierarchy and spatial development modes of tourist destination were built up.The results are shown as follows: there is a big gap in the intensity of tourism economy s connection among the cities of Chengdu-Chongqing urban agglomeration,and the spatial structure of “T” axis plus “C” circle is basically formed.The overall network density of the tourism economy s network of Chengdu-Chongqing urban agglomeration is low,and the connection between the node cities of the whole network is rare.The analysis of the centrality also shows that the regional tourism economy s network is mainly driven by the outward orientation with Chengdu and Chongqing as the core node cities,lacking of lower-tiered hub cities.Cohesive subgroups exist within the network of tourist economy,but their depth and breadth are not high.
