论文摘要
我们研究了费城土地保健（PLC）空置地段绿化计划对犯罪及其周围土地用途和业务类型的程度的影响。我们依靠倾向得分匹配分析来说明绿色和未经封闭的空置批次之间人口，经济，土地使用和业务特征的实质性差异。与无与伦比的分析相比，我们估计在匹配对分析中绿色的空置批次周围较大，更重要的犯罪减少。在高居民和商业土地较低的地区，空置地段绿化对犯罪的影响较大，并且由于附近的不同类型的企业而受到调节。
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.
