背景：街角商店的产品可能会受到供应商网络的影响，店主从这些供应商那里采购食品和饮料。到目前为止，这个供应商网络还没有得到很好的描述。方法：采用网络分析的方法，对美国巴尔的摩市食品沙漠地区的24家拐角店和42家食品/饮料供应商之间的联系进行分析，以确定不同的商店和供应商特征之间的相关性。结果：食品和饮料供应商分为两类：健康供应商网络(HSN)中主要提供健康食品/饮料的供应商(n=15)和不健康供应商网络(UHSN)中主要提供不健康食品/饮料的供应商(n=41)。与美国高速铁路相比，美国高速铁路与供应商之间的拐角店联系几乎增加了两倍(t=5.23，p<；0.001)，美国高速铁路核心地区的主要供应商更加多样化。与不那么有凝聚力和稀疏联系的HSN相比，UHSN显著更有凝聚力和更密集的联系，街角商店分享更多相同的不健康供应商(t=5.82；p<；0.001)。与非裔美国人相比，亚裔和西班牙裔街角店主与−供应商的联系平均少1.53%(p<；0.001)(p<；0.001)。结论：我们的研究结果表明，街角商店的HSN和UHSN有明显的差异。解决店主的种族/文化差异也可能是重要的考虑因素。
Background: Products in corner stores may be affected by the network of suppliers from which storeowners procure food and beverages. To date, this supplier network has not been well characterized. Methods: Using network analysis, we examined the connections between corner stores (n = 24) in food deserts of Baltimore City (MD, USA) and their food/beverage suppliers (n = 42), to determine how different store and supplier characteristics correlated. Results: Food and beverage suppliers fell into two categories: Those providing primarily healthy foods/beverages (n = 15) in the healthy supplier network (HSN) and those providing primarily unhealthy food/beverages (n = 41) in the unhealthy supplier network (UHSN). Corner store connections to suppliers in the UHSN were nearly two times greater (t = 5.23, p < 0.001), and key suppliers in the UHSN core were more diverse, compared to the HSN. The UHSN was significantly more cohesive and densely connected, with corner stores sharing a greater number of the same unhealthy suppliers, compared to HSN, which was less cohesive and sparsely connected (t = 5.82; p < 0.001). Compared to African Americans, Asian and Hispanic corner storeowners had on average −1.53 (p < 0.001) fewer connections to suppliers in the HSN (p < 0.001). Conclusions: Our findings indicate clear differences between corner stores’ HSN and UHSN. Addressing ethnic/cultural differences of storeowners may also be important to consider.
