阿肯色州全球稻米模型基于多国统计模拟和计量经济学框架。该模型按五个世界区域分类：非洲、美洲、亚洲、欧洲和大洋洲。每个区域都包括有供应部门、需求部门、贸易、库存和价格联动等式的国家模型。该模型中使用的所有方程都使用计量经济学方法或恒等式进行估计。估计数基于一系列解释变量，包括收入、人口、通货膨胀率、技术发展等外生宏观经济因素，特别是政府决定的政策变量，这些变量反映了各国干预其稻米部门经济的各种机制。各个国家的模式通过净贸易联系在一起，以认识到世界大米经济中各国的相互依存。
The Arkansas Global Rice Model is based on a multi-country statistical simulation and econometric framework. The model is disaggregated by five world regions: Africa, the Americas, Asia, Europe, and Oceania. Each region includes country models which have a supply sector, a demand sector, a trade, stocks and price linkage equations. All equations used in this model are estimated using econometric procedures or identities. Estimates are based upon a set of explanatory variables including exogenous macroeconomic factors such as income, population, inflation rate, technology development, and especially, government determined policy variables which reflect the various mechanisms by which countries intervene in their rice sector economy. Individual country models are linked through net trade to recognize the interdependence of countries in the world rice economy.
