集聚机制视角下探究新冠肺炎疫情对城市经济的冲击

Exploring the Economic Impact of the COVID-19 on Cities from the Perspective of Agglomeration Mechanism

新冠肺炎疫情是一次巨大的城市危机,破坏了集聚效应得以发挥的共享、匹配和学习机制,严重影响了城市经济正常运行。集聚机制作用的差异导致不同空间尺度上疫情冲击的异质性以及明显的复原力差异。基于此,建立全国、区域和城市三个层级的分析框架探究疫情带来的经济冲击。结果显示,发展水平更高、专业化生产能力更强的区域和城市遭受冲击更剧烈,但借助密切的区域关联和依托新一代信息技术的超空间集聚能够展现出更强的复原力。因此,加强区域关联、以城市群为核心建立协同联动的危机管理机制、升级传统集聚机制、转向超空间的网络化集聚是区域和城市经济抵御冲击的可行路径。

COVID-19,as a severe urban crisis,has destroyed the mechanisms of sharing,matching and learning,in which the agglomeration effect can be brought into full play,and seriously affected the normal operation of urban economy.The differences in the role of agglomeration mechanism leads to the heterogeneity of epidemic impact on different spatial scales and shows obvious differences in resilience.Based on this,a three-tier analytical framework at national,regional and urban levels has been established to explore the economic impact of the epidemic.Results show that regions and cities with better development and stronger specialized production capacity suffer more severe impact but show stronger resilience with the help of regional interconnection and hyperspace agglomeration relying on the emerging information technology.Strengthening regional interconnection,establishing a coordinated crisis management mechanism with urban agglomeration as the core,upgrading the traditional agglomeration mechanism and turning to hyperspace network agglomeration are the feasible ways for regional and urban economies to resist shocks.
