Diversification, vertical integration and economic resilience: evidence from intercity truck flows during COVID-19 in China
利用中国COVID-19期间高频卡车流量数据，发现区域产业多元化和垂直整合程度越高，其经济韧性越强，能更好应对疫情冲击，且这种效应随经济恢复而减弱。
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.
