The outbreak of COVID-19 epidemic has triggered a major global public health crisis. In this anti-epidemic sniper war sweeping the world, various countries and regions around the world have offered various anti-epidemic measures. Among them, big data technology has been widely used, which provides important information support for epidemic monitoring, resource allocation and people's livelihood security, and also provides valuable inspiration for further promoting smart governance.

Application Efficiency of Big Data Technology in Epidemic Prevention

In recent years, according to the strategy of the party and the country to build a network power, governments at all levels in China have vigorously promoted the construction of smart cities, actively applied information technologies such as the Internet, big data, Internet of Things and cloud computing, and achieved remarkable governance results in transportation, environmental protection, social governance and public services. A hero is known in the time of misfortune. In this invisible battle against the epidemic, big data technology came in handy and played a positive role. This is mainly reflected in three aspects.

First, provide basic information for scientific decision-making. Scientific decision-making is the "brain center" for successful anti-epidemic. Faced with the chaotic epidemic situation, governments at all levels have quickly established a cross-departmental full-process data management system, using mobile phone signaling data, railway air traffic data, GPS data applied on the Internet and so on. , to carry out epidemic monitoring and analysis, virus tracing, patients and close contacts tracking, personnel investigation and analysis, and constantly provide complete, continuous and accurate mass information, timely judge the epidemic situation and its trend, formulate reasonable plans, make scientific decisions, implement accurate prevention and control, and improve the efficiency of epidemic prevention work. Especially in the analysis of epidemic transmission path and population movement trajectory, big data technology provides irreplaceable insight and foresight based on data, algorithms and models.

Second, it is helpful to the precise allocation of anti-epidemic resources. Rational allocation of epidemic prevention resources is an important guarantee for epidemic prevention work. In the process of anti-epidemic, governments at all levels use the digital platforms of urban management, such as developing emergency resource publishing platforms and mask reservation systems, to accurately collect and record information such as material sources, resource types and cargo quantities, lay out and implement intelligent supply chain management, find out the resource needs of medical institutions, social organizations and urban residents, accurately calculate and allocate anti-epidemic resources, and allocate medical materials and other resources in advance to ensure that anti-epidemic materials can maximize their benefits and meet the production and living needs of the masses as much as possible. Moreover, optimizing resource docking, material allocation and accurate distribution through big data has also improved the autonomy and initiative of social subjects.

Finally, promote online public services. Faced with the closed situation during the epidemic period, governments at all levels actively responded to social needs, explored new ways and methods to handle public services online, opened up a digital government or smart government network platform, broke through the data barrier of government departments, broadened the scope of online services, improved the speed of online services, launched various "non-contact" or "no-meeting" services, and accessed relevant approval or service matters, so as to make data run more and people run less, and do as much as possible. Even libraries and cultural centers actively carry out online digital services to enrich people's cultural life at home during the epidemic.
