The Great Recession greatly exacerbated income inequality and might have also magnified unequal access to healthy food in the United States. There is a growing need to examine small-area effects of the Great Recession, especially among minority populations who were disproportionately targeted for predatory loans and experienced higher rates of foreclosure. To explore how the Great Recession interacted with a foodscape locally, a counterfactual quasi-experimental analysis extended by spatial econometric models is implemented to quantify the impact of foreclosure risk on supermarket access in Chicago. Black-majority, lower-income neighborhoods with higher risk of foreclosure experienced a small but significant worsening in food accessibility after the Great Recession, reflecting a compounding crisis of structural segregation and economic vulnerability. The results further suggest that inference interpretation is sensitive to both research design framing and underlying processes that drive geographically distributed relationships. For highly spatial phenomenon like segregation and foreclosure, making space explicit might not only clarify results but also enrich interpretation and understanding of underlying processes. It is essential to better understand the role segregation and structural inequality might have in perpetuating environments that contribute to social and health disparities.

大衰退极大地加剧了收入不平等，也可能加剧了美国获得健康食品的不平等。越来越需要研究大萧条的小范围影响，尤其是在成为掠夺性贷款的目标不成比例且止赎率较高的少数群体中。为了探索大萧条如何与当地的美食景观相互作用，实施了由空间计量经济学模型扩展的反事实准实验分析，以量化止赎风险对芝加哥超市准入的影响。在大萧条之后，具有较高止赎风险的黑人占多数的低收入社区的食物可及性出现了小幅但显着的恶化，反映了结构性隔离和经济脆弱性的复合危机。结果进一步表明，推理解释对研究设计框架和驱动地理分布关系的潜在过程都很敏感。对于隔离和止赎等高度空间现象，使空间明确不仅可以澄清结果，还可以丰富对潜在过程的解释和理解。必须更好地了解隔离和结构性不平等在导致社会和健康差异的长期环境中可能发挥的作用。对于隔离和止赎等高度空间现象，使空间明确不仅可以澄清结果，还可以丰富对潜在过程的解释和理解。必须更好地了解隔离和结构性不平等在导致社会和健康差异的长期环境中可能发挥的作用。对于隔离和止赎等高度空间现象，使空间明确不仅可以澄清结果，还可以丰富对潜在过程的解释和理解。必须更好地了解隔离和结构性不平等在导致社会和健康差异的长期环境中可能发挥的作用。
