尽管人们普遍认为，红线导致了城市的投资减少，但几乎没有对历史贷款模式进行实证分析。缺乏适当的数据和明确的红线定义造成了这一空白。本文回顾了近年来借贷研究中出现的定义和方法，并考虑如何将其应用于历史红线的研究。从20世纪40年代费城的地址级抵押贷款数据进行了分析，使用空间回归，“热点”分析和表面插值。采用多个定义的红线，重点是过程和结果，以及空间和统计关系的贷款，分析结果在一系列地图层，表明红线可能发生。除了提供一些贷款歧视的证据，这篇文章促进了明确的空间观的红线，有概念和方法论的影响，当代和历史的红线研究。摘要尽管人们普遍认为，红线导致了城市的投资减少，但对历史贷款模式的实证分析却很少。缺乏适当的数据和明确的红线定义造成了这一空白。本文回顾了近年来借贷研究中出现的定义和方法，并考虑如何将其应用于历史红线的研究。从20世纪40年代费城的地址级抵押贷款数据进行了分析，使用空间回归，“热点”分析和表面插值。采用多个定义的红线，重点是过程和结果，以及空间和统计关系的贷款，分析结果在一系列地图层，表明红线可能发生。除了提供一些贷款歧视的证据，这篇文章促进了明确的空间观的红线，有概念和方法论的影响，当代和历史的红线研究。
Despite widespread belief that redlining contributed to disinvestment in cities, there has been little empirical analysis of historical lending patterns. The lack of appropriate data and clear definitions of redlining has contributed to this void. This article reviews definitions and methods that have emerged from research on lending in recent years and considers how they can be applied to research on historical redlining. Address-level mortgage data from Philadelphia from the 1940s are analyzed using spatial regression, " hot spot " analysis, and surface interpolation. Employing multiple definitions of redlining that focus on process and outcome, as well as spatial and statistical relationships in lending, the analyses result in a series of map layers that indicate where redlining may have occurred. In addition to providing some evidence of lending discrimination, this article promotes an explicitly spatial view of redlining that has conceptual and methodological implications for research on contemporary and historical redlining.
