摘要

COVID-19加剧了全球粮食系统的脆弱性。本研究通过研究2019年至2020年期间冲击事件与社区特征的关系，评估了冲击事件对纽约市食物可及性的影响。我们利用社会经济和建筑环境因素对食物可及性进行建模，并利用空间计量模型和地理加权回归(GWR)对空间效应进行调整。我们的空间建模方法揭示了少数种族/民族群体与食物可及性之间的差异关系，以及收入影响的负变化。总体而言，我们的研究结果表明，粮食可及性在疫情期间恶化或两极分化，这表明需要改善网络连通性和规模较小的粮食储存，以实现公平和有弹性的粮食系统。

Neighborhood Food Accessibility and Health Disparity: Examining the Impact of COVID-19 Using Spatial Models

COVID-19 exacerbated food system vulnerabilities globally. This study assesses the impact of shock events on food accessibility in New York City (NYC) by examining its association with neighborhood characteristics between 2019 and 2020. We model food accessibility using socioeconomic and built environment factors, adjusting for spatial effects with spatial econometric models and geographically weighted regression (GWR). Our spatial modeling methods reveal diverging relationships between minority racial/ethnic groups and food accessibility, as well as a negative change in the effect of income. Overall, our results indicate that food accessibility worsened or polarized during the pandemic, suggesting the need for improved network connectivity and smaller-scale food stores to achieve equitable and resilient food systems.

期刊介绍： International Regional Science Review serves as an international forum for economists, geographers, planners, and other social scientists to share important research findings and methodological breakthroughs. The journal serves as a catalyst for improving spatial and regional analysis within the social sciences and stimulating communication among the disciplines. IRSR deliberately helps define regional science by publishing key interdisciplinary survey articles that summarize and evaluate previous research and identify fruitful research directions. Focusing on issues of theory, method, and public policy where the spatial or regional dimension is central, IRSR strives to promote useful scholarly research that is securely tied to the real world.
