空地绿化的影响以及土地使用和商业存在对犯罪的影响
The Effects of Vacant Lot Greening and the Impact of Land Use and Business Presence on Crime
摘要：
我们研究了费城土地保护（PLC）空地绿化倡议对犯罪的影响，以及周围的土地使用和商业类型在多大程度上缓和了这种干预。我们依靠倾向得分匹配分析来解释绿化和未绿化空置地块之间在人口、经济、土地使用和商业特征方面的重大差异。我们估计，与不匹配分析相比，在我们的匹配对分析中绿化的空地周围的犯罪减少更大，更显著。空地绿化对犯罪的影响在住宅用地高、商业用地低的地区更大，并因附近不同类型的企业的存在而有所缓和。
英文摘要：
We examine the effect of the Philadelphia LandCare (PLC) vacant lot greening initiative on crime and the extent to which surrounding land uses and business types moderate this intervention. We rely on a propensity score matching analysis to account for substantial differences in demographic, economic, land use, and business characteristics between greened and ungreened vacant lots. We estimate larger and more significant crime reductions around vacant lots that are greened in our matched pairs analysis compared to unmatched analyses. The effects of vacant lot greening on crime are larger in areas with high residential and low commercial land use and are moderated by the presence of different types of nearby businesses.
