Identifying the Spatio-Temporal Characteristics of Crime in Liangshan Prefecture, China

Abstract

Crime prevention and governance play critical roles in public security management. Liangshan Yi Autonomous Prefecture in Sichuan Province has a high crime rate, and spatio-temporal analysis of crime in this region could assist with public security management. Therefore, Liangshan Prefecture was selected as the research object in this study. The spatial crime data were obtained from China Judgments Online, and property crime, violent crime, and special crime (i.e., pornography, gambling, drugs, and guns) were analyzed. The findings were as follows. In terms of time characteristics (month, day, and hour), property crime tended to occur in autumn and winter, in the early month, on Wednesdays and Fridays, and at early morning. Violent crime tended to occur in winter and spring, on Mondays and Thursdays, and at night. Special crime occurred in spring and autumn, on Tuesdays, and in the daytime. In terms of spatial features, the central region of Liangshan Prefecture was the focal area for crime. There were obvious low-aggregation areas in the western region for special crime. The eastern region exhibited a high incidence of various crimes. Regarding the spatio-temporal evolution characteristics from 2013 to 2019, there were some obvious hotspots of violent and property crime in downtown and surrounding townships of Xichang City, which is the capital of Liangshan Prefecture. During the study period, the incidence of special crime has an obvious downward trend which shows that there are more new cold spots.

Analysis of the Movement Distribution Pattern of Violent Crime in Malaysia's Capital Region-Selangor, Kuala Lumpur, and Putrajaya

“…In another study, SDE was used to expose the various attributes of economic distribution accurately using spatial statistical analysis [29]. Another study used hotspot analysis, Mean Center, and standard deviation ellipse to examine the changing distribution of violent crime [30]. A fifth study used Mean Center and SDE to quantify the spatial distribution of geographic elements in terms of the center [31].…”

Crime on the mass transit system in Hong Kong: a hotspots and harmspots trajectory approach

“…As noted, the body of evidence from non-Western countries on hotspots is limited, so whether the same spatial patterns emerge in other locations is generally unknown, and this problem is exacerbated when it comes to mass transit environments. This is particularly the case in Asia, where studies of this nature are lacking (however, see Cheng et al, 2022;Liu et al, 2016;Wang et al, 2011, Wang andZhao, 2016). Furthermore, we are unaware of hotspots studies that look at crime harm rather than crime counts in these environments.…”

Construction and Analysis of Space–Time Paths for Moving Polygon Objects Based on Time Geography: A Case Study of Crime Events in the City of London

“…Thus, publicly available crime data are typically crime records posted on police departments' official websites, recording the location, time, and other attributes of each case. Crime point sets released by national police departments have been widely used in crime research [21][22][23][24][25][26]. For example, UCR (uniform crime reporting) has been applied to the study of the spatiotemporal evolution and prediction of crime [27][28][29].…”
