| With the development of the country and the progress of the times,new conflicts are developing in the direction of diversification and complication,and the resulting mass incidents occur frequently.Emergency management of public emergencies is imminent.Among them,the emergency management of mass incidents is a major issue that affects the stable development of countries,cities and regions.Shenyang has a long history and is an old industrial base in the northeast region,which is strongly supported by the state.The State Council has identified Shenyang as a critical central city in the northeast region,where the prevention,control and disposal of public security are more daunting than in ordinary cities.To improve the city’s management efficiency,realize the rapid and sustainable development of the city,and properly respond to the crisis,the government urgently needs reasonable,scientific and effective solutions.In this paper,we use the concept of knowledge management and combine it with big data to deal with complex mass crisis events from the perspective of knowledge management.Compared with traditional research concepts,the implementation and application of knowledge management can improve the process of urban mass crisis prevention,control and disposal,and provide new ideas and thoughts for effective response to mass crises.The concept of knowledge management emphasizes the use of big data technology as the basis of mass crisis prevention,control and management.It improves the prevention,control and disposal methods of mass crisis events from the source through the construction of prevention and control mechanism,demand mechanism,communication mechanism,sharing mechanism and coordination mechanism.In turn,it can improve the governmental mass crisis prevention,control and disposal mechanism and optimize the efficiency of urban crisis prevention,control and disposal.In this paper,research methods such as literature analysis method,experience summary method,and interview method are used.It provides new ideas for the study of prevention,control and disposal of urban group crisis in terms of the system of prevention,control and disposal of group crisis,the application of technology,and the change of concept.The research and investigation found that there are some problems in the prevention,control and management of mass crisis in the Shenyang city government that need to be improved.For example,Shenyang’s group crisis prevention early warning mechanism is not sound,lack of effective interest appeal expression mechanism,and insufficient tacit knowledge of crisis management experts,such as fragmentation of administrative departments and incomplete release of government crisis information.By comparing the current situation,finding the problems and analyzing the causes,it proposes appropriate countermeasures and suggestions for solutions with reference to the case.It is hoped that this paper will help improve the prevention,control and disposal of mass incidents in Shenyang and create a good public safety environment. |
