Will multi-industry supply chains' resilience under the impact of COVID-19 pandemic be different? A perspective from China's highway freight transport

Abstract

The pandemic caused by coronavirus disease 2019(COVID-19) continues to disrupt the global supply chain system, bringing new risks and challenges. The uncertainty created by COVID-19 makes it is difficult for various industries to deal with the pandemic. Since the pandemic, the supply chain's resilience has been discussed and examined in some studies. However, most existing works start from a single industry perspective or pay more attention to the disturbance caused by changes in the production side. Supply chain networks of different industries, mainly transport networks, are relatively limited under the epidemic's impact. In this paper, from the perspective of highway freight transport, a comprehensive competitiveness evaluation framework was proposed to reveal and the disruption and resilience of the supply chain under the outbreak based on nine indexes with five dimensions, including efficiency, capacity, activity, connectivity, and negotiability. Based on the availability of the data(Large-scale truck trajectory), we sorted out seven categories of Chinese industries(related to highway transport) and divided them into four categories respectively: (a) Slight disruption and worse resilience; (b) Slight disruption and remarkable resilience; (c) Serious disruption and worse resilience; (d) Serious disruption and remarkable resilience. The measurement results of supply chain network performance show that the industries (cold-chain, general products, and other industries) dominated by “Efficiency - Negotiability - Connectivity” are slightly disrupted (about 33%), forming a spatial diffusion with Wuhan(the city where the pandemic first broke out) as the disrupted center, spreading outward in a circle structure. Simultaneously, five urban agglomerations surrounding it have been impacted. By contrast, due to the strict isolation measures, the industries (building materials, construction, engineering, and high-value products industry) more vulnerable to be disrupted seriously (about 82%) tend to be the pattern of “Capacity - Activity”. However, a large-scale centralized disruption was observed in the Triangle of Central China urban agglomeration was presented, resulting in almost stagnation of industry development. Meanwhile, as the future of the pandemic remains uncertain, the supply chain represented by the engineering industry, construction industry, etc are deserved to be paid more attention in line with they are prone to large-scale centralized damage due to the disruption of a single city node.

Post‐covid‐19 Supply Chains: Challenges and Prospects

“…The pandemic caused by the COVID-19 pandemic continues to disrupt the global supply chain system, bringing new risks and challenges (Fu et al, 2022). The economic shocks that resulted from the pandemic have exposed many vulnerable spots in supply chains and increased apprehensions considering globalization.…”

Supply Chain Strategy in Philippine Construction Industry: A Case Study of Joint Risk Management Approach during the COVID-19 Pandemic

“…The company in the case study was experiencing a supply shortage. The construction supply chain is more vulnerable to COVID-19 because it is reliant on worldwide supply chains for materials, equipment, plant, and people [21]. Due to the lockdowns, material manufacturers have suspended operations, and critical construction supplies are unable to reach the site.…”

The Effects of Barriers and Freight Vehicle Restrictions on Logistics Costs: A Comparison before and during the COVID-19 Pandemic in Brazil

“…Freight restrictions can influence transportation capacities negatively, which in turn increase logistics costs [36]. Products must comply with existing regulations, such as those related to the use of refrigerated trucks or to specific industry activities, when loaded by freight vehicles [37]. Freight restrictions should represent a measure of the improvement of the activity's performance, and yet, Bontempo et al [35] report that the National Transportation Confederation argues that this measure increases delivery costs.…”

“…The pandemic has represented an opportunity for logistics service providers (LSPs) to guarantee sufficient resiliency to mitigate the risks caused by negative events [39]. The recovery capacity of the freight transportation was already more robust than that in passenger transportation, but the industry has improved its resilience capacity with the pandemics [37]. The COVID-19 pandemic, however, has had several different influences on the transport industry.…”
