数字经济对市域旅游业高质量发展水平的空间效应及机制

Spatial Effect and Impact Mechanism of Digital Economy on Tourism Industry High-quality Development in Chinese Cities

数字经济已成为推动旅游业高质量发展的关键驱动力。数字经济对旅游业发展质量的影响在城市尺度尚未检验其空间溢出效应及传导路径。为此,融合多源数据构建2011—2019年中国285个地级及以上城市的面板数据集,从时空维度对数字经济与旅游业高质量发展之间的演变特征进行分析,并运用空间杜宾模型和空间中介效应模型对其空间溢出效应、空间传导机制及空间异质性进行实证检验。结果表明:(1)研究期内,数字经济和旅游业高质量发展水平整体呈上升趋势,两者之间存在显著的正向空间关联。(2)数字经济不仅有利于本地旅游业发展质量的提高,而且通过空间溢出效应作用于邻近城市。(3)在高互联网地区和高市场化地区,数字经济对旅游业高质量发展的空间溢出作用更为明显。(4)数字经济通过提升旅游市场吸引力和旅游创业活跃度的方式有效激活了市场活力,进而促进旅游业高质量发展。

Digital economy has become the key driving force to promote the high-quality development of tourism industry. The impact of digital economy on the quality of tourism development has not yet been tested on the spatial spillover effect and conduction path at the urban scale. This paper combines multi-source data to build a panel dataset of285 cities at prefecture level and above in China from 2011 to 2019,analyzes the evolution characteristics of high-quality development of digital economy and tourism from the perspective of time and space,and uses spatial Durbin model and spatial intermediary effect model to empirically test its spatial spillover effect, spatial action mechanism and spatial heterogeneity. The results show that: 1) From 2011 to 2019, the overall level of high-quality development of China's digital economy and tourism is on the rise,and there is a significant positive spatial correlation. 2) Digital economy is not only conducive to the improvement of the quality of local tourism development, but also acts on neighboring cities through spatial spillover effects. This conclusion is still valid after a series of robustness tests. 3) The analysis of spatial heterogeneity shows that the spatial spillover effect of digital economy on the high-quality development of tourism industry is more obvious in areas with high Internet level and high marketization. 4) The test results of the intermediary effect model show that the digital economy has effectively activated the market vitality by improving the tourism market attraction and tourism entrepreneurship activity,thereby promoting the high-quality development of the tourism industry.
