• aidsSystemData-DIB.xlsx contains the first combination of the USDA ERS data into a single tabular format. It also contains the formulas for the calculation of derived data. • aidsSystemData3.csv is the .xlsx file converted to .csv for import into R. • aidsvdataInbrief.R contains all code used to estimate and calculate elasticities. The following packages must be installed for the script: 'tidyverse', 'lubridate', 'micEconAids', and 'broom'. • Results.xlsx contains all results. Tabs are labeled as “results_” lags between price and quantity, and “h” or “m” to indicate Hicksian or Marshallian. • all.Rdata contains all results and intermediate objects.• aidsSystemData-DIB.xlsx 首次将美国农业部经济研究服务局（United States Department of Agriculture Economic Research Service, USDA ERS）的数据整合为单一表格格式，同时包含衍生数据的计算公式。 • aidsSystemData3.csv 为转换为CSV格式的文件，用于导入R语言环境。 • aidsvdataInbrief.R 包含所有用于估计与弹性计算的代码。运行该脚本需预先安装以下R包：'tidyverse'、'lubridate'、'micEconAids' 与 'broom'。 • Results.xlsx 包含全部实验结果，其工作表命名规则为"results_"后接价格与数量的滞后阶数，后缀“h”或“m”分别表示希克斯（Hicksian）需求弹性与马歇尔（Marshallian）需求弹性。 • all.Rdata 包含全部结果与中间对象。
