文章简介:
以往研究发现以绅士化为代表的社区变化会与新的多功能步道相关,但这种相关性在不同城市、不同社区的表现却有所不同。本研究探索了2010至2015年期间在美国大城市(田纳西州孟菲斯市、路易斯安那州新奥尔良市和华盛顿特区)投入使用的三条多功能步道沿线社区的绅士化或升级变化。本研究采用了基于非参数化倾向性得分匹配和动态DID模型的准实验研究设计,分别检验这些多功能步道的宣布建设和投入使用对周围社区的影响。本研究的实证结果支持以往研究呈现出的多功能步道影响的多样性和复杂性。具体来讲,对整体样本的分析发现多功能步道的投入使用会推动周围低收入(可绅士化)社区的绅士化进程,但是多功能步道的宣布建设影响则有限;此外,一部分证据证明了多功能步道的宣布建设和投入使用可能会推动高收入(不可绅士化)社区的进一步升级。针对每条多功能步道的个案分析发现绅士化会在一些社区发生,但并不是所有可绅士化社区都会发生。此外,研究发现多功能步道可能并不是其周围社区绅士化的唯一诱因,周围高收入社区在多功能步道宣布建设和投入使用后的进一步升级,也可能会带来周围低收入社区的绅士化。另外,绅士化的过程可能伴随着白人居民对低收入的少数族裔社区的入侵,即挤出原有的少数族裔居民。因此,想要建设步道等绿色基础设施的政策制定者、规划者和倡导者需要考虑当地环境的复杂性,以制定针对性的政策来减轻绅士化及其带来的原住居民被迫迁出等问题。
Abstract:
Scholars have found that many new multiuse trails are associated with neighborhood change like gentrification. However, gentrification of adjacent, gentrifiable neighborhoods is not universal, and studies of localized effects of trails are needed. This study documents gentrification and upgrading in both gentrifiable and non-gentrifiable neighborhoods along three multiuse trails funded and opened in large U.S. cities (Memphis, TN; New Orleans, LA; Washington D.C.) between 1993 and 2015. We use a case-control, pre-post design with Dynamic Difference-in Difference models, incorporating Nonparametric Propensity Score Matching for the control group selection, to test the announcement and opening effects in neighborhoods adjacent to these trails. We document heterogeneity and complexity of neighborhood change both within and across these trail corridors. When pooling the three trails, we find evidence of opening effects but little evidence of announcement effects in gentrifiable neighborhoods, and some evidence of both effects in non-gentrifiable neighborhoods. Our trail-specific analyses indicate that gentrification occurred in some, but not all, trail corridors and gentrifiable neighborhoods. Evidence indicates gentrification in trail corridors may not result solely from announcement/opening effects, but may be initiated or accelerated by the upgrading in surrounding non-gentrifiable neighborhoods following trail announcement and opening. Additionally, the gentrification process may also involve the encroachment of white residents into minority (i.e., predominantly Black), gentrifiable neighborhoods. Policymakers, planners, and advocates working to build green infrastructure like trails need to consider the complexities of local context when developing strategies to mitigate adverse consequences of gentrification and displacement.
