This study develops a methodology to distinguish vacant land types and introduces a classification scheme using a citywide vacancy inventory. Using Minneapolis, MN as a study area, three land characteristics associated with vacant properties - parcel size, ownership, and land use - are examined. Kaplan-Meier survival rates are then estimated to evaluate and compare the durations of vacancy between 2005 and 2015. The results indicate that a vacant property, in general, has the lowest probability to remain vacant within its first two years after becoming vacant. Smaller-sized parcels tend to result in a longer-term vacancy; while publicly owned, industrial, institutional, and/or recreational vacancies show similar tendencies. From this analysis, this study then develops a six-category classification scheme that can be used as (1) a novel tool to inventory vacant urban lands, (2) a diagnostic tool to identify repurposing opportunities, and (3) reliable means of comparing vacant properties across localities.
本研究开发了一种区分空地类型的方法，并引入了一种使用全市空置清单的分类方案。以明尼苏达州明尼阿波利斯市为研究区域，研究了与空置房产相关的三个土地特征——地块大小、所有权和土地用途。然后估计了卡普兰-迈耶生存率，以评估和比较2005年至2015年期间的空置持续时间。结果表明，一般来说，空置房产在空置后的头两年内保持空置的概率最低。较小尺寸的地块往往会导致长期空置；而公有、工业、机构和/或娱乐用途的空置则表现出类似的趋势。基于此分析，本研究随后开发了一种六类分类方案，该方案可作为（1）一种用于盘点城市空置土地的新颖工具，（2）一种识别重新利用机会的诊断工具，以及（3）一种比较不同地区空置房产的可靠方法。
