摘要：经济韧性是城市应对结构变化和实施转型的能力，其对于区域可持续发展至关重要。空间结构是集聚经济发展过程中收益与成本在不同空间中差异化演变的结果，其作为资源要素多中心集聚的体现，对经济韧性具有何种影响？文章从城市形态视角出发，探讨了不同空间尺度下城市多中心空间结构对经济韧性的影响效应与作用机制。研究结论如下：第一，城市内部多中心空间结构对经济韧性具有促进作用，而外部多中心空间结构对经济韧性的影响呈现先促进后抑制的倒“U”形曲线特征，而且多中心空间结构对经济韧性的影响效应存在显著的时空异质性；第二，对经济韧性进行shift-share分解后发现，城市内部多中心空间结构可以通过产业结构韧性与竞争力韧性来影响整体经济韧性，而外部多中心空间结构影响经济韧性的传导机制在不同区间内存在差异；第三，内部多中心空间结构可以通过承载力效应与经济效率效应来影响经济韧性，而外部多中心空间结构可以通过要素流动效应与网络外部性效应来影响经济韧性，而且作用机制主要通过竞争力韧性进行传导；第四，对不同规模城市而言，受到内部集聚程度差异与外部网络结构差异的影响，支撑经济韧性提升的最优空间结构也存在差异。文章的研究为推动产业结构转型升级以及建设具有韧性的城市提供了政策参考。

Summary: Economic resilience is the ability of a city to respond to structural changes and innovate development paths, and spatial structure is the result of the differential evolution of income and cost in different spaces in the process of agglomeration economy development. As the embodiment of polycentric agglomeration of resource elements, what impact does the spatial structure have on economic resilience? Based on a theoretical framework of polycentric spatial structure affecting economic resilience, this paper makes an empirical test by using the matching data of nighttime lights and urban economic indicators. From the perspective of urban form, it discusses the influence mechanism of polycentric spatial structure on economic resilience under different spatial scales, and accurately identifies which cities in different sizes are suitable to choose the polycentric spatial structure. The conclusions are as follows: First, the impact of urban internal polycentric spatial structure on economic resilience is promotion, while the impact of urban external polycentric spatial structure on economic resilience is an inverted U-shaped curve relationship of first promotion and then inhibition, and the impact of spatial structure on economic resilience has significant spatio-temporal heterogeneity. Second, by conducting a shift-share decomposition of economic resilience, it shows that the internal polycentric spatial structure can affect the overall economic resilience by acting on industrial structure resilience and competitiveness resilience, while the transmission mechanism of external polycentric spatial structure on the overall economic resilience is different in different sections. Third, the internal polycentric spatial structure can affect economic resilience through carrying the capacity effect and economic efficiency effect, while the external polycentric spatial structure can affect economic resilience through the factor flow effect and network externality effect, and the transmission mechanism is mainly conducted through competitiveness resilience. Fourth, for cities in different sizes, the optimal spatial structure supporting the improvement of economic resilience is also different due to the differences in internal agglomeration degree and external network structure. This paper is helpful to expand the related research on the influencing factors of urban economic resilience, construct the theoretical framework of co-evolution between urban polycentric spatial structure and economic resilience. The policy suggestions are as follows: First, differentiated choices of spatial development models should be made to stimulate urban economic resilience. Second, the spatial structure should be relied on to achieve the restructuring of factors and promote the transformation and upgrading of industrial structure. Third, multi-dimensional policies should be implemented to open up the channels through which the polycentric spatial structure affects economic resilience.
