The devastating Canterbury Earthquakes of 2010 and 2011 left an indelible mark on the city of Christchurch. The social and economic upheaval that immediately followed the Earthquakes has, in time, been replaced with a period of rebuild and transformation. In this study we investigate the effects that the Canterbury Earthquakes had on two important and inter‐related phenomena in the city: alcohol availability and crime. More specifically, we investigate how alcohol outlets and crime across six different categories changed in magnitude and spatial distribution pre‐ (end‐2009) and post‐ (end‐2014) earthquake. We do this using a variety of geospatial techniques including a relatively new method: the spatial point pattern test which allows for the identification of changes in spatial patterns at the local level. Results indicate that both alcohol outlets and crime have decreased in magnitude since the Canterbury Earthquakes. Using the spatial point pattern test we found statistically significant differences in spatial point patterns for both alcohol outlets and all crime types pre‐ to post‐earthquake. The similarity in the differences of the spatial distributions of alcohol outlets and crime provides a first empirical clue of their potential association in the city post‐earthquake.

新西兰克赖斯特彻奇灾后酒类商店和犯罪的空间稳定性

2010 年和 2011 年毁灭性的坎特伯雷地震给基督城留下了不可磨灭的印记。地震后紧随其后的社会和经济动荡已及时被重建和转型期所取代。在这项研究中，我们调查了坎特伯雷地震对城市中两个重要且相互关联的现象的影响：酒精供应和犯罪。更具体地说，我们调查了六种不同类别的酒类商店和犯罪在地震前（2009 年底）和地震后（2014 年底）的震级和空间分布上的变化。我们使用各种地理空间技术来做到这一点，包括一种相对较新的方法：空间点模式测试，它允许识别本地空间模式的变化。结果表明，自坎特伯雷地震以来，酒类销售点和犯罪率均有所下降。使用空间点模式测试，我们发现酒类商店和地震前后所有犯罪类型的空间点模式在统计上存在显着差异。酒类店和犯罪空间分布差异的相似性为它们在城市震后的潜在关联提供了第一个经验线索。
