我们利用2007年至2009年阿肯色州的面板数据集来识别和确定食物沙漠对学区肥胖率的影响。我们将食物沙漠定义为食物供应有限的低收入地区。使用经典的面板数据模型和空间误差模型，我们发现在阿肯色州的学区肥胖率和食物沙漠的存在之间没有统计学上的显着关系。这一发现在不同的模型规格，空间，面板或横截面分析，以及数据中有或没有城市学区是一致的。
We utilize a panel data set from 2007 to 2009 on the state of Arkansas to identify and determine the effect of food deserts on school district obesity rates. We define food deserts as low-income areas with limited food access. Using both classical panel data models and spatial error models, we find no statistically significant relationship between school district obesity rates and the existence of food deserts in Arkansas. This finding is consistent across different model specifications, in spatial, panel or cross-sectional analysis, and with or without urban school districts in the data.
