城市群旅游经济网络的空间结构与权力演变

Spatial Structure and Power Evolution of Tourism Economic Network of Urban Agglomeration

运用引力修正模型和社会网络分析法,通过Ucinet 6.0软件分析长三角和珠三角旅游经济网络的空间结构和评价指标。研究结果表明:1长三角旅游经济网络空间结构呈现出中部、东部网络相对密集,西南部、北部稀疏的格局;珠三角网络空间结构呈现出东南部网络相对密集,西部、东北部稀疏的格局。2009—2014年长三角与珠三角节点的度数中心度、接近中心度和网络密度总体增加,而中间中心度和节点重要度总体下降。2整体来看,长三角网络权力总体朝着失衡方向发展,珠三角网络权力总体朝着均衡方向发展;网络权力空间分布差异明显;长三角和珠三角网络权力层次结构明显、角色定位清晰、功能明确。针对旅游经济网络的空间结构和权力演变提出了相应建议。

This paper used the gravity model and social network analysis, built the spatial structure and evaluatian index of Changjiang River Del- ta and the Pearl River Delta tourism economic networks with Ucinet 6.0. The results showed：（DThe spatial structure of Changjiang River Delta pre- sented the central, eastern areas was relatively dense, southwest, north was sparse pattern, the spatial structure of Pearl River Delta presented the pat- tern that southeast was relatively dense and western, northeastern was sparsely. The degree centrality, closeness centrality and network density of nodes in Changjiang River Delta and the Pearl River Delta tourism economic networks generally increased while the centrality and the importance of node pr- esented a downtrend during the period of 2009 - 2014. ~）On the whole, the network power of Changjiang River Delta developed in an unbalanced di- rection, the network power of Pearl River Delta developed in the balanced direction in general. The results showed significant difference in the spatial distribution of network power, and the network power hierarchy, role definition and function between Changjiang River Delta and Pearl River Delta are very clear. In the end, suggestions for the spatial structure of tourism economic ties and network power corresponding were put forward.
