选择北京、上海作为客源地,山东省各地级市作为目的地,基于社会网络分析方法,分析各节点在网络中的中心性、结构洞水平以及形成的核心-边缘结构,探究不同客源地游客旅游线路网络结构的差异。结果表明:以京沪为客源地形成的旅游网络结构存在一定的差异。从整体网络角度看,北京-山东旅游线路在整体网络的密度和中心势方面均大于上海-山东。从网络节点的角度看,北京作为客源地形成了以青岛为中心的旅游线路网络;而在以上海为客源地的网络中,形成了以威海为网络中心,泰安为重要枢纽城市的目的地空间结构。研究结论对现有旅游线路在理论、研究方法和实践方面有重要启示和指导意义。 Based on the analysis of social networks, Beijing, Shanghai as the tourist destination and all prefecture-level cities in Shandong Province are selected as the destinations, and the centrality and structure of each node in the network and the core-edge structure are analyzed. Tourist travel network structure of the differences. The results show that there are some differences in the tourism network structure formed by tourists from Beijing and Shanghai. From an overall network perspective, Beijing-Shandong tourist routes are all larger than Shanghai-Shandong in overall network density and center potential. From the network node’s point of view, Beijing as a tourist source to form the Qingdao-centered tourist route network; and in Shanghai as the source of the network, formed Weihai as the network center, Tai’an is an important hub city purposes Spatial structure. The conclusions of the study have important implications and guiding significance for the existing tourist routes in theory, research methods and practices.
