长三角数字经济与旅游产业高质量发展耦合协调的时空演进及驱动因素

Spatio-Temporal Evolution and Driving Factors of the Coupling Coordination between Digital Economy and High-Quality Tourism Development in the Yangtze River Delta

摘要: 为评估和揭示数字经济与旅游产业高质量发展耦合协调的时空演进和驱动因素，通过构建两大系统评价指标体系，运用熵值-CRITIC和耦合协调模型测算了长三角地区数字经济与旅游产业高质量发展水平及耦合协调度，运用空间计量模型验证创新能力的驱动作用。结果表明：研究期内长三角数字经济呈现波动上升，旅游产业高质量发展水平呈现先升后降的态势，两者均存在明显的空间差异；两者耦合协调水平先平稳上升后缓慢下滑，在空间上呈现东南高、西北低的阶梯化分布格局，空间集聚特征明显，以高–高集聚和低–低集聚为主；空间杜宾模型显示创新能力促进了两者的耦合协调，并对邻近城市产生正向的空间溢出效应。

Abstract: To evaluate and reveal the spatiotemporal evolution and driving factors of the coupling coordination between the digital economy and the high-quality development of the tourism industry, this study constructs evaluation frameworks of two systems. Using the entropy-CRITIC weighting method and coupling coordination model, we measure the development levels and coupling coordination degree of the digital economy and high-quality development of the tourism industry in the Yangtze River Delta (YRD). Spatial econometric models are employed to verify the driving role of innovation capacity. The results indicate that: 1) During the study period, the digital economy in the YRD exhibited a fluctuating upward trend, while the high-quality development of the tourism industry showed an initial rise followed by a decline, both with significant spatial disparities. 2) The coupling coordination level between the two systems first rose steadily and then declined slowly, displaying a stepped spatial pattern of “high in the southeast, low in the northwest.” Spatial agglomeration was evident, dominated by high-high and low-low clusters. 3) Spatial Durbin model results demonstrate that innovation capacity significantly promotes coupling coordination and generates positive spatial spillover effects on neighboring cities.
