东北三省城市间旅游经济联系网络结构与发展模式构建

Network Structure and Development Model Construction of Tourism Economic Connection among Cities of Three Provinces in the Northeast of China

基于修正引力模型和社会网络分析方法,选取2006—2018年研究时段,探究东北三省城市间旅游经济联系网络结构特征。研究发现:东北三省城市间旅游经济联系逐渐增强,其主要结构由单轴向多轴转变;部分城市的辐射能力、扩散能力、控制能力显著增强,区域旅游经济发展分化现象处于缓和状态;旅游经济的网络密度逐渐增加,进一步来看,核心区内部、边缘区内部以及核心区与边缘区之间的网络密度有所提升;旅游经济联系空间网络中凝聚子群空间自组织能力显著提升,凝聚子群内部和凝聚子群间联系密度稳步提高。据此,从点、线、面三个层次构建东北三省城市间旅游经济发展的不同模式,并提出具体发展建议。

Based on the modified gravity model and social network analysis method,this paper selects the research period from 2006 to 2018 to explore the structural characteristics of tourism economic connection network among cities in the three provinces of Northeast China.The results show that the tourism economic relations among cities in the three provinces of Northeast China are gradually strengthened,and the main structure of tourism economic relations is transformed from uniaxial to multi-axial.The radiation ability,diffusion ability and control ability of some urban core nodes are significantly enhanced,and the differentiation phenomenon is in a moderate state.The network density of tourism economy increases gradually.Further,the network density within the core area,the edge area and between the core area and the edge area increases.The spatial self-organization ability of condensed subgroups in the spatial network of tourism economic links has been significantly improved,and the density of connections within and between condensed subgroups has been steadily increased.Based on this,different modes of tourism economic development among cities in Northeast China are constructed from three levels of point,line and plane,and specific development suggestions are put forward.
