Major crisis events are closely related to the "unprecedented changes in a century". In the digital era, the global major crisis events under the "unprecedented changes in a century" have both generality and particularity. Taking the prevention and control of COVID-19 epidemic as an example, we can find that under the "unprecedented changes in a century", China is facing some problems in the process of responding to major global crises. The macro causes of these problems are: some mechanisms, concepts and personnel in China still have typical characteristics of the industrial era, It failed to adapt to the digital age and the new environment created by the major global crisis events in the digital age. The micro causes are attributed to the emergency management system and ability, personnel and theoretical innovation. Implementing corresponding countermeasures against these causes and effectively strengthening China's response advantages can enhance the possibility of China's successful response to major global crisis events under the "unprecedented changes in a century".
