武陵山片区旅游经济空间关联网络的城乡融合效应

Urban-rural integration effect of the spatial correlation network of tourism economy in the Wuling Mountain Area

系统刻画武陵山片区旅游经济空间关联网络特征并探讨其城乡融合效应,对于凝聚旅游经济发展合力和扩大其对城乡融合的网络溢出效应具有重要的实践价值。论文综合运用修正引力模型、社会网络分析法和空间计量模型等,在勾勒2010—2021年武陵山片区旅游经济空间关联网络及城乡融合水平演变特征的基础上,系统探索武陵山片区旅游经济空间关联网络的城乡融合效应。研究发现:①武陵山片区旅游经济空间关联网络呈现出复杂化、多线程的网络结构形态,武陵源区、永定区、凤凰县、恩施市等县域在旅游经济空间关联网络中居于核心位置。②武陵山片区城乡融合总体水平相对较低,呈缓慢提升态势,但城乡融合水平的区域差距有所扩大,在空间上城乡融合水平较高的县域向外溢出形成高水平集聚区。③武陵山片区旅游经济空间关联网络中心性的提高显著促进了城乡融合,且这种正向外部性具有空间异质性特征,原国家级贫困县网络中心性的城乡融合赋能效应更加突出,而省际交界区的县域网络中心性对城乡融合的促进作用并不显著。④武陵山片区旅游经济空间关联网络中心性对城乡融合存在显著的空间溢出效应,且空间外溢具有边界效应,外溢系数在110 km处达到峰值,此后随距离衰减。研究结果可为推动武陵山片区城乡融合和共同富裕提供实践参考。

Systematically characterizing the spatial correlation network of tourism economy in the Wuling Mountain Area and exploring its urban-rural integration effects has practical value for the cohesion of tourism economic development and expanding its network spillover effect on urban-rural integration.Using the modified gravity model,social network analysis method,and spatial measurement model,this study systematically explored the urban-rural integration effect of the spatial network of tourism economy in the Wuling Mountain Area based on the characteristics of the spatial correlation network of tourism economy and the evolution of the level of urban-rural integration from 2010 to 2021.The results show that:1)The spatial correlation network of tourism economy in the Wuling Mountain Area presented a complicated and multi-threaded network structure,and Wulingyuan District,Yongding District,Fenghuang County,and Enshi City were at the core of the spatial correlation network of tourism economy.2)The overall level of urban-rural integration was relatively low in the Wuling Mountain Area,showing a slow upgrading trend,but the regional difference in the level of urban-rural integration had expanded,and the counties with a higher level of urban-rural integration exhibited a spatial spillover effect to form high-level agglomerations.3)The enhancement of spatial correlation network centrality of tourism economy in the Wuling Mountain Area significantly promoted urban-rural integration,and this positive externality showed spatial heterogeneity,the urban-rural integration effect of the network centrality of the former national-level poverty-stricken counties was more prominent,while the promotional effect was not significant in the counties of the inter-provincial boundary areas.4)There was a significant spatial spillover effect of spatial correlation network centrality of tourism economy on urban-rural integration in the Wuling Mountain Area,and the spatial spillover had a boundary effect,with the coefficient of spillover reaching a peak at 110 km,and thereafter it decayed with distance.The results of the study can provide practical references for promoting urban-rural integration and common prosperity in theWuling Mountain Area.
