Mechanism and spatial effects of the digital economy affecting tourism innovation efficiency in the Yangtze River Delta region from the"local-neighboring area"perspective
The digital economy is an important engine that can guide the rapid optimal allocation and regeneration of resources and achieve high-quality development of the tourism economy.Studying the impact of the digital economy on tourism innovation efficiency from the perspective of"local-neighboring area"spatial effect has important theoretical and practical significance for the high-quality development of the tourism industry.Taking the Yangtze River Delta as the research object,this study constructed a theoretical framework for the impact of the digital economy on tourism innovation efficiency.Based on the measurement of the development level of the digital economy and tourism innovation efficiency,this study explored the dynamic response relationships between the two and the spatial effects of the impact of the digital economy on tourism innovation efficiency.The findings are as follows:1)Temporally,the mean value of tourism innovation efficiency in the Yangtze River Delta region showed a U-shaped pattern of first decreasing and then increasing.The overall level of efficiency was relatively low,and the region with high values kept growing over time.The tourism innovation efficiency of Shanghai and Zhejiang Province was higher than the average value of the Yangtze River Delta region.The gap between the tourism innovation efficiency of Jiangsu Province and the average value of the Yangtze River Delta region was narrowing,and it exceeded the average value of the Yangtze River Delta region in 2018,while the tourism innovation efficiency of Anhui Province had always been lower than the average values of the Yangtze River Delta region.2)Spatially,tourism innovation efficiency generally presented a trend of high in the east and low in the west,and high in the south and low in the north.The high-value areas were mainly distributed in the economically developed areas or the areas with high abundance of tourism resources,which had apparent characteristics of economic and resource orientation.The spatial agglomeration characteristics of tourism innovation efficiency were apparent,and the"high-high"and"low-low"types dominated the agglomeration modes.3)The digital economy was the Granger cause of tourism innovation efficiency,and the response of tourism innovation efficiency to the impact of the digital economy presented the characteristics of cyclical fluctuations and time lag.The digital economy had a significant positive direct effect on local tourism innovation efficiency,but the influence on tourism innovation of neighboring cities is stage-specific.Currently,the trickle-down effect of digital factor resources has a positive effect on the tourism innovation of neighboring cities.
