Research On Public Security Intelligence Analysis Model Based On Spatial Spillover Effect

At present,economic activities and social behaviors are more frequent,which leads to the increased mobility of time and space factors of crime,thus the spillover effect of crime is more obvious.Traditional public security intelligence analysis technology makes static analysis on the factors that affect robbery crime,makes clear the hot spots of crime and puts forward corresponding countermeasures,but cannot put forward suggestions on combating and preventing robbery crime transmission from a global perspective.Introducing spatial measurement method into intelligence analysis can combine time and space factors,sketch out the three-dimensional dynamic process of crime spillover,clarify the influence of various influencing factors on crime,establish a three-dimensional system of crime attack and prevention,and help to form spatial departmental linkage,effectively advance the time node of crime trend prediction,and provide decision support for public security organs to reduce crime flow and spillover.Based on the theory of information hinterland and growth pole in spatial metrology,combined with the theory of daily activities and rational choice in criminology,this study makes visual analysis,selects the common spatial metrology model as the basic model,and modifies the model accordingly to form a model with high fitting degree Taking the number of robbery cases in six districts of B city in 2013 as the research data,this stduy makes an empirical analysis,verifies the value and applicability of the model,and confirms the necessity,importance and authenticity of the crime spillover effect test.Through this model,we can get the spillover strength,spillover range,heterogeneity and convergence of robbery crime in the study area,and draw the basic situation of robbery crime spillover in the map,which makes the transmission dynamics of robbery crime clear.This study constructs an intelligence analysis model through theory and makes an empirical analysis.This model makes up for the deficiency that the existing intelligence analysis methods are too static.It can not only make clear the hot spots of crime,but also make clear the possible scope of criminal behavior to the maximum extent,and provide an effective tool for intelligence workers to put forward targeted prevention and crackdown countermeasures.
