“一带一路”沿线中国主要节点城市旅游经济空间网络研究

Research on the spatial network of tourism economy of major node cities along “the Belt and Road” in China

以“一带一路”沿线中国16个沿海主要节点城市、19个内陆主要节点城市为研究对象,借助修正的万有引力模型分析节点城市旅游经济空间网络的联系度,运用社会网络分析法从网络密度、网络中心性、核心-边缘模型三个维度研究节点城市旅游经济空间网络结构。研究结果显示:“一带一路”倡议推动了主要节点城市旅游经济联系度的提高,沿海节点城市中的上海与杭州、内陆节点城市中的重庆与成都在2012年与2016年均保持了最高的旅游经济联系度;沿海节点城市旅游经济空间网络中,上海是核心节点,广州、厦门是次核心节点,共同控制沿海节点城市联系网络;内陆节点城市旅游经济空间网络中,重庆、武汉是其双核心节点,协同控制内陆节点城市联系网络;位于城市群内部的节点城市具有更稳固的网络中心地位。因此,应着力提升节点城市旅游经济实力,强化节点城市旅游资源优势,强化节点城市旅游经济空间网络联系,以推动中国旅游经济的发展。

Taking 16 coastal major nodes cities and 19 inland major node cities along “the Belt and Road” as research object,the connectivity of tourism economic space network of node cities is analyzed from the three dimensions of network density,network centricity and core-edge model with the help of a modified gravitation model.The results show that the“the Belt and Road”promotes the improvement of tourism economic connectivity of nodes cities along the route,Shanghai and Hangzhou in coastal node cities and inland node cities and Chongqing and Chengdu in inland node cities have maintained the highest tourism economic linkage in 2012 and 2016;in the network of tourism economy of coastal node cities,Shanghai is the core node city,and Guangzhou and Xiamen are the sub-core node cities,which jointly control the coastal node city contact network;in the space network of tourism economy of inland node cities,Chongqing and Wuhan are the two core cities, which jointly control the connection network of coastal node cities;in the space network of tourism economy of inland node cities,Chongqing and Wuhan are two core node cities,which jointly control the connection network of inland node cities;and the node cities located in the inner city cluster have a more stable network center position.Therefore,the tourism economic strength of node cities can be enhanced,the advantageous tourism resources of node cities can be strengthened,and the spatial network connection of tourism economy of each city can be promoted,so as to promote the development of China’s tourism economy.
