黄河流域旅游经济系统韧性的时空差异特征及其影响因素

Spatio-temporal Differences and Influencing Factors of Resilience of Tourism Economic System in the Yellow River Basin

探析旅游经济系统韧性状态对推进旅游高质量发展具有科学参考价值。该文以黄河流域79个地级市为研究单元,采用核密度估计、变差函数和空间计量模型,揭示2005—2019年黄河流域旅游经济系统韧性水平的时空差异特征及影响因素。结果表明:①黄河流域旅游经济系统韧性水平整体偏低,时序上呈现出先升后降的阶段性特征,空间上存在显著的正相关性,呈现出“下游>中游>上游”的块状分布格局。②旅游经济系统韧性空间变异幅度不断缩小,由空间自相关引起的结构化分异不断增强;韧性水平的空间差异主要体现在局部微观尺度,东—西方向空间差异最大,南—北方向空间差异最小。③黄河流域旅游经济系统韧性存在显著的空间溢出效应,财政自给水平、市场规模、旅游专业化、信息化水平对黄河上、中、下游韧性的提升具有直接促进作用,信息化水平、市场规模对韧性水平的提高存在正向溢出效应。

Exploring the resilience of tourism economic system has scientific reference value for promoting high-quality tourism development.Taking 79 cities in the Yellow River basin as research units,this paper uses kernel density estimation,variogram and spatial econometric model to analyze the spatio-temporal difference characteristics and influencing factors of the resilience level of tourism economic system in the Yellow River basin from 2005 to 2019.The results are as follows.①The overall resilience level of tourism economic system in the Yellow River basin is low,showing the stage characteristics of first rising and then falling in time series,and there is a significant positive correlation in space,showing a blocky distribution pattern of"downstream>midstream>upstream".②The spatial variation range of the resilience of tourism economic system is shrinking,and the structural differentiation caused by spatial autocorrelation is increasing.The difference of resilience level in all directions is small,and the spatial difference is mainly reflected in the local micro-scale,with the largest difference in east-west direction and the smallest difference in south-north direction.③There is a significant spatial spillover effect on the resilience of tourism economic system in the Yellow River basin.Financial self-sufficiency,market scale,tourism specialization and informatization have a direct promoting effect on the resilience of tourism economic system in the Yellow River basin,while informatization level and market scale have a positive spillover effect on the resilience.
