For many of the infected regions, the economy will fall sharply in the short term, and then rebound after the epidemic is over, but COVID-19 we hope is unlikely to have a huge long-term impact. Epidemic prevention and control measures from local governments will be a key factor.
How it has affected China In February 2020, China’s manufacturing purchasing manager index (PMI) was 35.7%, down 14.3 percentage points from the previous month. Meanwhile, the Production Index was 27.8%, down by 23.5 percentage points from the previous month, indicating that manufacturing production activity had slowed down radically. According to analysis of data segments such as power generation, population migration, and transportation; the work resumption rate in China is about 65%. COVID-19 may have a far-reaching impact on the capacity layout and supply chain network of many enterprises. Multinational enterprises in particular will further improve their disaster emergency mechanisms and supply chain management.
