中国粮食产量预测方程

       利用投入产出分析、变系数预测模型对中国2030全国粮食产量进行预测。一个预测方程为:

      

          

                        

                               

式中,为粮食单位面积产量;常数项的变系数为2.29T为时间趋势,变系数为-2.51D为政策变量(在人的积极性充分发挥的年份中取值为1否则为0),变系数为3.56X4为受灾面积系数,变系数为-1.78X6为单位面积耕地化肥使用量(折纯),变系数为6.26X7为灌溉面积比重系数,变系数为3.64X9为单位面积耕地平均使用役畜数,变系数为3.19X11为农家肥使用系数,变系数为4.48X12为比价,变系数为3.10CA为常数调整项(预测用)。
