调查不列颠哥伦比亚省温哥华微观空间分析单元中犯罪事件数据的空间集中度和空间稳定性。2003-2013年地理参照犯罪数据，代表四种财产犯罪类型（商业爆窃、恶作剧、车内盗窃、车辆盗窃）的分析，考虑到犯罪集中在街道段和街道交叉口的水平，以及通过使用非参数空间点模式测试，确定了空间点模式在成对和纵向上下文中的稳定性。温哥华的财产犯罪高度集中在一小部分街道段和交叉口，根据犯罪类型，2013年只有5%的街道段和交叉口。空间点模式测试表明，空间稳定性几乎总是存在时，考虑所有的街道段和交叉口。然而，当只考虑有犯罪的街道段和交叉口，空间稳定性只存在于最近几年的成对比较和适度稳定的纵向tests.Despite犯罪率下降，发生在温哥华，随着时间的推移，仍然存在空间稳定性在理论发展的水平。然而，在制定情境犯罪预防举措时必须谨慎。
Investigate the spatial concentrations and spatial stability of criminal event data at the micro-spatial unit of analysis in Vancouver, British Columbia.Geo-referenced crime data, 2003-2013, representing four property crime types (commercial burglary, mischief, theft from vehicle, theft of vehicle) are analyzed considering crime concentrations at the street segment and street intersection level as well as through the use of a nonparametric spatial point pattern test that identifies the stability in spatial point patterns in pairwise and longitudinal contexts.Property crime in Vancouver is highly concentrated in a small percentage of street segments and intersections, as few as 5 % of street segments and intersections in 2013 depending on the crime type. The spatial point pattern test shows that spatial stability is almost always present when considering all street segments and intersections. However, when only considering the street segments and intersections that have crime, spatial stability is only present in recent years for pairwise comparisons and moderately stable in the longitudinal tests.Despite the crime drop that has occurred in Vancouver, there is still spatial stability present over time at levels suitable for theoretical development. However, caution must be taken when developing initiatives for situational crime prevention.
