我国五星级酒店空间网络结构演变特征研究

The Evolution Features of the Spatial Network Structure of Five-star Hotels in China

基于2001—2019年我国31个省(区、市)五星级酒店的空间面板数据,采用社会网络分析法与OLS回归分析法探究其空间网络结构及其演变特征.研究表明:(1)我国五星级酒店整体网络呈“两升两降”的结构特征,网络关联性在增强,网络发育程度日渐完善,逐步向均衡性方向演变.(2)五星级酒店网络中具有自主行动能力的省(区、市)增多,其演变经历了“东—中—西”的扇形扩散路径;五星级酒店网络经历了由双核心节点(北京、上海)到多核心节点(天津、四川和河南)的扩散演变,核心节点的外溢效应明显.(3)五星级酒店网络整体呈现出核心区逐渐扩大,边缘区不断减少的趋势.核心区呈现出北部沿海—南部沿海—内陆的扩张路径,但核心区对边缘区的外溢效应有所减弱,空间网络有待于进一步优化.(4)网络密度与五星级酒店数量呈正相关,与其数量分布差异呈负相关,而网络等级度和网络效率则相反.

Based on the space panel data of five-star hotels in 31 provinces and regions in 2001-2019,the method of social network analysis and OLS regression were used to explore the spatial network structure and evolution characteristics.The study shows that:①The overall network of five-star hotels in China is in a structural characteristics of“two rises and two drops”,with network correlation enhencing,the degree of network development increasing,and gradually evolving to the direction of equilibrium.②There are more and more provinces with autonomous mobility in five-star hotels network,and the evolution of such provinces and regions has experienced the fan diffusion path of“east-middle-west”.The network has experienced the diffusion evolution from doublecore nodes(Beijing,Shanghai)to multi-core nodes(Tianjin,Sichuan and Henan),and the spillover effect of the core nodes is obvious.③The network as a whole shows a trend of the gradual expansion of the core area and the marginal area constantly decreasing.The core area presents an expansion path from north coastal region to south region coastal and then to inland,but the spillover effect of the core area on the marginal area has weakened,and the spatial network needs to be further optimized.④Network density was positively correlated with the number of five-star hotels and negatively with their number distribution differences,while the degree of network rank and network efficiency were just the opposite.
