长三角地区数字经济与旅游经济耦合协调的时空分异研究

Research on the Spatiotemporal Differentiation of the Coupling and Coordination between Digital Economy and Tourism Economy in the Yangtze River Delta Region

文章使用长三角地区2011—2021年面板数据,用熵值法构建数字经济与旅游经济指数,运用耦合协调模型和空间自相关模型分析二者的协调融合水平及空间相关关系。研究表明:2011—2021年,长三角地区数字经济与旅游经济指数和区域耦合协调水平总体呈上升趋势;城市间耦合协调情况存在空间差异,总体呈东部高、西部低、省会城市高、其他城市低的阶梯分布;耦合协调度还具有显著的空间集聚特征,“高—高”集聚区集中在上海辐射圈内,涵盖浙北、苏南地区,“低—低”集聚区主要集中在苏北、皖北地区,中部地区不显著,但这种集聚效应在逐渐减弱。

This paper uses the panel data of the Yangtze River Delta region from 2011 to 2021 to construct an index of the digital economy and tourism economy with the entropy method,and uses the coupling coordination model and spatial autocorrelation model to analyze the coordination and integration level and spatial correlation between the two.The research shows that:from 2011 to 2021,the digital economy and tourism economy index and regional coupling coordination level in the Yangtze River Delta region are on the rise;there are spatial differences in the coupling and coordination between cities,with an overall ladder distribution of high in the east,low in the west,high in provincial capital cities,and low in other cities;the coupling coordination degree also has significant spatial agglomeration characteristics.The“high high”agglomeration areas are concentrated within the Shanghai radiation circle,covering the northern and southern regions of Zhejiang,while the“low low”agglomeration areas are mainly concentrated in the northern and northern regions of Anhui.The central region is not significant,but this agglomeration effect is gradually weakening.
