摘　　要：自“长三角一体化”上升为国家战略以来,大量文献开始聚焦对长三角区域的贸易结构和贸易高质量发展的研究,但鲜有文献涉及对贸易韧性的研究。本文选取长三角26个城市2010~2021年的面板数据,实证检验长三角城市群金融集聚对贸易韧性的影响。其中城市贸易韧性水平通过贸易量指标计算得到,城市金融集聚水平通过熵值法测度得到。研究发现,长三角城市群金融集聚不仅直接赋能贸易韧性,而且通过促进产业结构升级,实现贸易韧性的提升。进一步分析表明,该赋能作用存在异质性和非线性的特征。在城镇化水平更高以及金融集聚效率更强的城市,赋能作用更为显著。此外,随着产业结构水平的提高,长三角城市群金融集聚对贸易韧性的赋能作用存在边际效用递减的非线性特征。Since the“Integration of the Yangtze River Delta”became a national strategy,a great deal of literature has fo⁃cused on the study of the trade structure and high-quality development of the Yangtze River Delta region.In this paper,we use the data of 26 cities in the Yangtze River Delta from 2010 to 2021 to empirically examine the impact of financial agglomeration on trade resilience of Yangtze River Delta Economic Zone,during which the trade resilience of cities is calculated by trade volume index,and the financial agglomeration level of cities is constructed by using the entropy-weight method.It is found that financial agglome⁃ration of Yangtze River Delta Economic Zone not only directly engenders trade resilience,but also enhances trade resilience by pro⁃moting the upgrading of industrial structures.Further analysis shows that there are heterogeneity and non-linearity in above empowe⁃ring effect.In cities with higher level of urbanization and higher efficiency of financial agglomeration,the role of empowerment is more significant.Moreover,the enabling effect of financial agglomeration on trade resilience in Yangtze River Delta Economic Zone is diminishing returns nonlinear as the level of industrial structure improves.
