成渝地区双城经济圈旅游经济联系的空间结构及驱动因素研究

A Study on the Spatial Structure and Driving Factors of Tourism Economic Ties in the Double-City Economic Circle in Chengdu and Chongqing

基于社会网络理论,以成渝地区双城经济圈为例,借助社会网络分析法(Ucinet 6.0)探索旅游经济联系的空间相互关系及结构形态,继而运用QAP相关分析(二次指派程序)与地理探测器揭示其驱动因素.结果发现:成渝地区双城经济圈旅游经济联系逐渐增强,旅游经济联系整体网络逐步完善;各城市旅游经济联系网络的“核心-边缘”结构逐渐弱化,区域内旅游经济联系两极化现象明显改善;成渝地区双城经济圈旅游经济联系网络发展受旅游资源丰度、邮电业务总量、空间邻接关系、固定资产投资、专利授权数以及旅游收入占GDP比重等多种驱动因素的综合影响;各驱动因子对成渝地区双城经济圈旅游经济联系的影响在不同时间节点上具有异质性.

Based on the Social Network theory,this paper explored the spatial relationship and structural form of the tourism economic relationship in the Double-City Economic Circle in Chengdu and Chongqing with the help of UCINET6.0,and then reveals its driving factors by using Quadratic Assignment Procedure(QAP) correlation analysis and geographical detector.The results showed that the tourism economic ties in the Double-City Economic Circle in Chengdu and Chongqing were gradually strengthened,and the overall tourism economic ties network was gradually improved,while the "Core-periphery" structure of the tourism economic ties network of each city was gradually weakened,the phenomenon of polarization of regional tourism economic links has been improved significantly.The development of the tourism economic network in the Double-City Economic Circle in Chengdu and Chongqing was affected by various driven factors including the abundance of tourism resources,the volume of post and telecommunications business,spatial proximity,fixed asset investment,the number of patents granted and the proportion of tourism income to GDP.The impact of each driving factor on the tourism economic relationship of Double-City Economic Circle in Chengdu and Chongqing was heterogeneous at different time points.
