在全球气候变化加剧与经济不确定性增加的背景下,提升城市群韧性与创新效率的协同发展对推动区域高质量发展具有重要意义。基于2015—2023年长三角城市群27个城市的多源数据,构建涵盖经济、社会、生态、基础设施维度的城市韧性评价体系与包含创新投入、产出维度的创新效率评价体系,采用CRITIC赋权法、超效率SBM模型与耦合协调模型,系统分析二者的时空演化特征及协同机制。结果表明:城市韧性呈现“多极引领、梯度扩散”的时空特征,区域差异逐步缩小;创新效率呈N形波动趋势,空间格局由单核集聚演变为多中心联动;耦合协调度显著提升,形成“双高值中心+沿江协调带”的层级化格局,发展重心向东南方向迁移。研究结果可为长三角高质量一体化发展提供韧性-创新协同发展的科学依据。
