近年来，基于地点的枯萎病补救计划作为一种减少犯罪的方法越来越受欢迎。这项研究估计了费城全市空地绿化计划对多年来犯罪变化的影响，以及这些影响是否受到附近土地使用的影响。空地绿化计划进行了评估，使用准实验和实验设计。在准实验分析中使用了熵距离加权，以使对照地段与绿化地段在预先存在的犯罪趋势上具有可比性。固定效应的差异中的差异模型被用来估计的影响，空地绿化计划在准实验和实验分析。据估计，在准实验性和实验性评价中，空地绿化可减少犯罪总数和多个亚类。当空地位于火车站和酒类销售点附近时，整治空地对减少犯罪的影响较小。当空地位于活跃的商业区附近时，空地整治的犯罪率下降幅度更大。有一些暗示性的证据表明，当位于干预前社会凝聚力水平较高的社区时，空地绿化的影响更大。研究结果表明，空地绿化提供了一个可持续的方法，以减少犯罪在弱势社区，其影响可能会因周围不同的土地使用。为了更好地了解基于场所的枯萎病整治干预措施减少犯罪的机制，未来的研究应该在实施整治工作之前和之后，测量人类活动和周围地区的邻里社会化。
Place-based blight remediation programs have gained popularity in recent years as a crime reduction approach. This study estimated the impact of a citywide vacant lot greening program in Philadelphia on changes in crime over multiple years, and whether the effects were moderated by nearby land uses. The vacant lot greening program was assessed using quasi-experimental and experimental designs. Entropy distance weighting was used in the quasi-experimental analysis to match control lots to be comparable to greened lots on pre-existing crime trends. Fixed-effects difference-in-differences models were used to estimate the impact of the vacant lot greening program in quasi-experimental and experimental analyses. Vacant lot greening was estimated to reduce total crime and multiple subcategories in both the quasi-experimental and experimental evaluations. Remediating vacant lots had a smaller effect on reducing crime when they were located nearby train stations and alcohol outlets. The crime reductions from vacant lot remediations were larger when they were located near areas of active businesses. There is some suggestive evidence that the effects of vacant lot greening are larger when located in neighborhoods with higher pre-intervention levels of social cohesion. The findings suggest that vacant lot greening provides a sustainable approache to reducing crime in disadvantaged neighborhoods, and the effects may vary by different surrounding land uses. To better understand the mechanisms through which place-based blight remediation interventions reduce crime, future research should measure human activities and neighborly socialization in and around places before and after remediation efforts are implemented.
