The construction of emergency management mechanism is not only a key component of emergency management work，but also an important issue to improve the resilience of social development. As a gathering area of high-end elements such as capital，technology，data，information，and talents，CBD has a serious impact on the construction of urban emergency management mechanism，and its hidden dangers seriously affect the overall security of the urban economy. Improving the CBD emergency management mechanism and establishing and improving the CBD disaster prevention，mitigation and relief system are the key measures to maintain the economic security and social stability of the CBD，and also an important part of promoting the modernization of CBD governance. In the future，CBD should continuously strengthen CBD emergency management capabilities through measures such as scientifically formulating emergency management development plans，improving financial stability and risk prevention and control mechanisms，extensively carrying out emergency science popularization and emergency mobilization，strengthening the construction of emergency shelter facilities，and building a “smart emergency brain”. Build and improve the emergency management mechanism，improve the modernization level of CBD governance capacity，and improve the overall security of the city’s economy.
