中文摘要：文章采用真实货运"流动数据"表征城市物流联系，从公路、铁路、水路、航空4类物流联系分析长江经济带物流网络，同时引用复杂网络理论和仿真攻击策略评估了物流网络结构的静态韧性和动态韧性，并通过模拟新冠疫情冲击探讨了上海等主导性节点城市物流网络在应对风险时的韧性表现。结果表明:①长江经济带形成了以公铁陆运为主干、水运为辅助、航空为补充的物流网络，其中各省会城市发挥着重要枢纽功能;②其物流网络层级性、异配性显著，具备良好传输韧性，但物流资源过度集中于核心城市，易引发局部区域的闭塞和僵化;③物流网络结构的韧性能力并非固定不变，而是随风险冲击增大呈现阶段变化特征，核心部分未遭受严重破坏，整体网络就仍能维持正常运转;④新冠疫情模拟下，上海等核心城市"封城"并未使物流网络陷入困境，其他城市可增强自身中介作用来弥补网络核心缺失，实现网络结构的再平衡。由此，从物流基础建设、主导性节点和脆弱性节点3方面提出物流网络结构韧性的优化建议。

外文标题：Resilience of Logistics Network Structure in the Yangtze River Economic Belt under the Background of Risk Normalization

外文摘要：This article constructs an urban logistics network based on the real freight data as logistics"flow data",analyzes the logistics network of the Yangtze River Economic Belt from four-type logistics connections of highway,railway,waterway and air,and combines complex network theory and different simulation attack strategies to evaluate the static resilience and dynamic resilience of logistics network structure.It also explores the resilience performance of logistics network in response to risk shocks by simulating the COVID-19 pandemic.The results show that:1)The Yangtze River Economic Belt has formed a logistics network with the highway and railway transportation as the mainstay,water transportation as the auxiliary,and air transportation as the supplement,in which provincial capital cities play an important hub function.2)The logistics network has significant hierarchy and heterogeneity,and has good transmission resilience,but logistics resources are excessively concentrated in core cities,which may cause blockage and rigidity in local areas;3)The resilience ability of logistics network structure is not fixed,but shows a stage change characteristic with the increase of risk shocks.The core network can still maintain the normal operation of the whole network without serious damage.4)In the COVID-19 pandemic simulation experiment,the lockdown of Shanghai and other core cities has not caused the logistics network to collapse.Other cities can strengthen their own intermediary role to make up for the lack of network core,and rebalance the network structure.Therefore,from the perspectives of logistics infrastructure,dominant nodes,and vulnerable nodes,it proposes some optimization suggestions for the resilience of the logistics network structure.
