Abstract: With the steady improvement of China’s comprehensive national strength,the frequency of large-scale events is increasing day by day,and the resulting security protection tasks are also escalating,imposing a heavy burden on security protection work. Informatization construction is the core path to relieve the pressure of security protection work,break through the limitations of traditional security protection,and improve the efficiency of security protection work. Based on the core connotation of new-quality public security combat effectiveness,by focusing on the bottlenecks restricting the informatization construction of security protection for large-scale events,such as the barriers to information sharing,insufficient application of technologies,and potential risks to data security,this paper proposes three optimization paths,namely constructing an integrated security protection information sharing system,deepening the application of intelligent algorithms,and improving the security protection mechanism,in the hope of providing a reference for enhancing the security protection effectiveness of large-scale events.

Key words: new-quality public security combat effectiveness, large-scale events, security protection, informatization, optimization path
