摘　　要：在外部不确定冲击多发的背景下,能否通过优化城市空间布局增强城市经济韧性成为思考方向。本文借助夜间灯光数据反映城市多中心程度,并基于2013—2021年长江经济带的城市面板数据,实证研究了多中心空间结构对城市经济韧性的影响,发现多中心空间结构对城市经济韧性有显著的正向影响,并且该影响存在显著的双门槛效应。机制分析发现,多中心结构能够通过提高土地价值进而增强城市经济韧性。异质性分析发现,多中心结构对经济韧性的影响作用存在要素禀赋和区位异质性。据此认为,城市空间规划时除了关注多中心空间结构带来的正向影响外,还要结合城市经济规模和其他特征适时调整城市发展策略。In the context of frequent uncertain external shocks,it has become a considerable direction whether the economic resilience of cities can be enhanced by optimizing the spatial layout of cities.Based on the degree of urban multi-center reflected by night light data and the city panel data of the Yangtze River Economic Zone from 2013-2021,this paper empirically investigates the impact of multi-center spatial structure on the economic resilience of cities,and finds that the multi-center spatial structure has a significant positive impact on the economic resilience of cities,and the impact has a significant double-threshold effect.Mechanism analysis finds that the multi-center structure can enhance urban economic resilience by increasing land value.Heterogeneity analysis finds that there is factor endowment and location heterogeneity in the effect of multi-center structure on economic resilience.Consequently,it is contended that during urban spatial planning,aside from recognizing the positive ramifications of polycentric spatial arrangements,urban development strategies ought to be aptly adjusted in tandem with urban economic magnitudes and other pertinent characteristics.
