分析了补偿投资与减产(因固定资产报废而造成的)之间的关系动态化,给出了改进的动态投入产出模型,用几个例子对改进模型进行了验算。研制了改进模型的核电规划计算软件和国民经济规划软件,均获得较好的计算结果。对原模型的稳定性问题,也进行了理论分析和证明。理论分析和数值计算得出的结论是一致的,说明改进模型是必要的,正确的和可行的。 This paper analyzes the dynamic relationship between compensation investment and production reduction (caused by the retirement of fixed assets), gives an improved dynamic input-output model, and checks the improved model with several examples. The improved model of nuclear power planning software and national economic planning software have been developed, all of which have achieved good results. The stability of the original model, but also conducted theoretical analysis and proof. The conclusions drawn from the theoretical analysis and numerical calculation are consistent, which shows that improving the model is necessary, correct and feasible.
