Damage to the manufacturing industry causes serious problems, including damage to the supply chain. Recovery requires an understanding of the types of industries that have suffered damage, but at present analyses are limited to qualitative analyses.
Therefore, in this study we investigated the impacts of COVID-19 using the industrial production index and seasonal adjustment method.
As a results of the analysis showed the spread of COVID-19 infection had the strongest impact on transportation equipment, whereas production of pharmaceuticals, masks, electrical equipment, etc. increased.
First, the areas damaged during the early stage of infection were calculated at the prefectural level. Second, the degree of impact on the manufacturing industry was quantitatively determined. Third, these results enabled comparison with past external shocks.
In addition, the spread of COVID-19 has caused supply chains to deteriorate due to the concentration of production at specific bases, and production activities in those regions have sharply declined. Therefore, to mitigate the impact of external shocks on a region, it is necessary to diversify the local industries.
