【摘要】 基于2011～2021年长江经济带110个城市的面板数据，构建长江经济带数字新质生产力和农业高质量发展的综合评价指标，采用面板回归、耦合协调度模型和空间变差函数探究两系统之间的耦合关系及时空演化。结果表明：(1)长江经济带数字新质生产力和农业高质量发展间存在显著的动态耦合关系，且数字新质生产力对农业高质量发展的影响较强。(2)均值水平方面，中游地区<上游地区<下游地区。(3)空间分布方面，长江经济带的耦合协调度在全局上呈现空间正相关性，在局部上高高集聚区主要在长三角城市群，低低集聚区主要在成渝城市群和黔中城市群。耦合协调度的空间随机性影响逐步增强，结构性影响逐步降低，整体空间差异在减少，但仍存在局部不平衡。更多还原

【Abstract】 Based on panel data from 110 cities in the Yangtze River Economic Belt(YREB) from 2011 to 2021, this study constructed a comprehensive evaluation for the digital new-qualitative productivity and high-quality agricultural development in the YREB.Panel regression, coupling coordination degree models, and spatial variation function were employed to explore the coupling relationship and spatio-temporal evolution.The results indicated that there was a significant dynamic coupling relationship between the two systems.The digital new-qualitative productivity had a stronger impact on high-quality agricultural development.The mean level was in the order of the middle reaches < the upstream reaches < the downstream reaches.Regarding spatial distribution, the coupling coordination degree exhibited a spatial positive correlation globally.The high-high agglomeration areas were mainly concentrated in the Yangtze River Delta urban agglomeration and the low-low agglomeration areas were mainly in the Chengdu-Chongqing urban agglomeration and Central Guizhou urban agglomeration.The spatial randomness effect on the coupling coordination degree was gradually increasing, while the structural effect was gradually decreasing.Overall, the spatial differences were decreasing, and the local imbalances still existed.更多还原
