“海丝”沿海节点城市旅游经济联系的网络结构研究

Tourism-economy-based Network Structure of Node Cities Along Maritime Silk Road

基于修正重力模型结合社会网络方法,以海上丝绸之路节点城市为研究样本,选取国内旅游、入境旅游、综合旅游三个维度测度城市旅游经济的关联程度,通过网络密度、中心度、凝聚子群等分析方法对16个节点城市旅游经济网络结构进行量化分析。研究发现,各节点城市网络结构密度值较低,且入境旅游高于国内旅游;入境旅游城市经济网络形成以上海、福州、厦门、泉州、广州和深圳为核心的节点结构,对其他节点城市发挥着支配效应和中介效应;海峡西岸形成以厦门、福州、泉州居的凝聚子群区,核心城市不明显;三亚、海口与其他城市的关联度最低。通过节点城市合作群,构建一个关联度高、协调性强的一体化旅游经济空间网络,可为海上丝绸之路文化旅游开发提供理论依据。

This paper takes the node cities of the Maritime Silk Road as the research sample on the basis of integration between modified gravity model and social network method,it selects three dimensions of domestic tourism,inbound tourism and comprehensive tourism to measure the correlation degree of urban tourism economy and conducts a quantitative analysis on tourism-economy-based network structure of 16 node cities in terms of network density,centrality,cohesive subgroup and etc.The study finds out that the density of network structure of each node city is low,and the inbound tourism is higher than that of domestic tourism;the economic network of inbound tourism city formed a node structure with Shanghai,Fuzhou,Xiamen,Quanzhou,Guangzhou and Shenzhen as the core,exerting dominant and intermediary effects on other node cities;the West Bank of the Strait forms a cohesive sub-cluster with Xiamen,Fuzhou and Quanzhou as the core but without a definite node city;Sanya and Haikou demonstrate the lowest correlation with other cities.It is proposed that an integrated tourism economic spatial network with high correlation and coordination could be constructed by means of connecting the cooperation group of node cities,which could provide a theoretical basis for the development of cultural tourism along the Maritime Silk Road.
