摘要

本研究的目的是用时间序列(2015-1980)预测伊拉克水稻作物的生产、消费和粮食缺口,以及影响自给率和进口量的经济因素。基于统计程序(Minitab & SPSS),采用指数平滑法预测水稻作物的生产、消费和营养缺口。单、双两种(2016-2025)均为单指数平滑法,其MSE值最低,为(11450.4)。对于2025-2016年的水稻产量消耗,双指数平滑法最准确,MSE为87100.7。对于粮食缺口,单指数平滑是同一时期的最佳预测指标,其最低值(MSE)为84100.1。自给率受五个因素(耕地面积、进口量、可供消费、进口/生产比、代表封锁年数的虚拟变量)和影响进口数量的因素(大米产量、可供消费、边境价格、人口数量)的影响。

Forecasting production,consumption and the food gap of rice crop in Iraq using Exponential Smoothing method
"The aim of this research is to predict the production, consumption and food gap of the rice crop in Iraq, as well as the economic factors that affect the self-sufficiency ratio and the quantity of imports with the time series (2015-1980). Based on the statistical program (Minitab & SPSS) Is the Exponential Smoothing method for Forecasting the production, consumption, and nutritional gap of the rice crop. Two types of single and double (2016-2025) was the single Exponential Smoothing method for having the lowest MSE value of (11450.4) . As for the consumption of the rice yield for the period (2025-2016), the double Exponential Smoothing method was the most accurate (MSE), which is 87100.7. As for the food gap, the single Exponential Smoothing is the best predictor for the same period in terms of the lowest value (MSE) 84100.1. The self-sufficiency ratio was affected by five factors (cultivated area, Imports, available for consumption, import / production ratio, the dummy variable representing years of blockade), and Factors affecting the quantity of imports (rice production,available for consumption, border prices, the number of the population Al- Muthanna University All rights reserved"
