Application of analysis on the impact of major public health events on special work of chemical enterprises

Abstract—In order to reveal the impact of Covid-19 on special work of chemical production enterprises in China, including Chinese funded, Sino foreign joint venture, foreign funded and foreign funded joint venture enterprises. The mutual influences between the two were studied by collecting safety commitment and Covid-19 logs in Zhejiang Province, and correlation method and event study were adopted. Although the level of Covid-19 was lowered to level 3 on March 23 by Zhejiang Province, it would take 46 days, 31 days, 61 days and 46 days for the four types to return to the normal special work level respectively. Therefore, for similar major public health events, chemical production enterprises should timely avoid their impact on special operation activities related to normal inspections and maintenances.
