基于灰色分离模型的黑龙江省水稻比较优势分析的预测

Comparative Advantage Prediction for Rice Production of Heilongjiang Province Based on the Grey Separating Model

摘要: 根据灰色模型的原理,以黑龙江省水稻20多a的产量、规模为研究对象,在数值试验的基础上得到了适合于黑龙江省水稻综合比较优势分析的灰色分离法的预测模型,对水稻综合比较优势做出预测,表明灰色分离模型在农作物比较优势分析的预测中具有一定的优势。

Abstract: According to the principle of the grey model,taking the outputs and planting area of rice in Heilongjiang province for more than 20 years as the research objects,the prediction model in analyzing optimal grey separating model and forecasting the comparative advantage of rice was established.The results indicate that the grey separation model plays an important role in economic analysis for grain crops.
