摘要

本文运用人工神经网络和计量经济学方法对2009 - 2013年伊朗大米进口趋势进行了预测,并对预测结果进行了比较。结果表明,与计量经济学技术和其他神经网络方法(如循环网络和多层感知器网络)相比,脚前神经网络具有更小的预测误差和更好的性能。结果表明:2009-2013年,我国大米进口量呈上升趋势,其中2009-2010年增幅最大,为25.72%;大米进口的增加导致大量外汇流出该国,也对国内生产造成了不可弥补的损害,无论是在价格上还是在数量上。考虑到这些情况,经济政策制定者应该寻求减少大米进口增加趋势的方法;对国内大米生产商进行更多的投资和规划。

Forecasting Iran's rice imports trend during 2009-2013.
In the present study Iran's rice imports trend is forecasted, using artificial neural networks and econometric methods, during 2009 to 2013, and their results are compared. The results showed that feet forward neural network leading with less forecast error and had better performance in comparison to econometric techniques and also, other methods of neural networks, such as Recurrent networks and Multilayer perceptron networks. Moreover, the results showed that the amount of rice import has ascending growth rate in 2009-2013 and maximum growth occurs in 2009-2010 years, which was equal to 25.72 percent. Increasing rice import caused a lot of exchange to exit out of the country and also, irreparable damage in domestic production, both in terms of price and quantity. Considering mentioned conditions, economic policy makers should seek ways to reduce increasing trend of rice import; and more investment and planning for domestic rice producers.
