摘要

本文通过结合高频卡车流量和COVID-19期间中国的封锁政策冲击来研究经济弹性。我们发现，在多元化和垂直一体化水平较高的地区，卡车流量在应对COVID-19冲击时的下降幅度较小。动态上，随着区域间经济联系的恢复，多样化和垂直一体化的调节作用逐渐减弱。多样化和一体化也减轻了来自外地感染病例的负面影响。在全国城际货车流网络中，产业结构属性与经济弹性的关联在中心性较低的区域更为突出。

Diversification, vertical integration and economic resilience: evidence from intercity truck flows during COVID-19 in China

Abstract This article examines economic resilience by combining high-frequency truck flows and the lockdown policy shock during COVID-19 in China. We discover that the truck flows in regions with higher levels of diversification and vertical integration see a smaller decrease in response to the COVID-19 shock. Dynamically, such moderating effects of diversification and vertical integration get smaller with the recovery of interregional economic linkages. Diversification and integration also mitigate the negative impact from nonlocal infection cases. The association between the industrial structure attributes and economic resilience is more prominent in regions with lower centrality in the nationwide intercity truck flow network.

期刊介绍： The aims of the Journal of Economic Geography are to redefine and reinvigorate the intersection between economics and geography, and to provide a world-class journal in the field. The journal is steered by a distinguished team of Editors and an Editorial Board, drawn equally from the two disciplines. It publishes original academic research and discussion of the highest scholarly standard in the field of ''economic geography'' broadly defined. Submitted papers are refereed, and are evaluated on the basis of their creativity, quality of scholarship, and contribution to advancing understanding of the geographic nature of economic systems and global economic change.
