摘要
在现实的经济系统中,由于社会经济活动的复杂性、多变性和随机性,用确定性变量来描述多变但又有一定规律性的社会经济现象是不符合实际的,为此,运用随机变量的分布理论研究随机投入产出模型具有现实意义。以直接消耗系数和最终需求为正态型随机变量的前提,研究了随机投入产出模型的某一类问题,并最终导出了各部门随机投入产出模型中产出量所满足的方程。
In real economic systems, it is not realistic to describe the regular but changing socio-economic phenomena with certainty variables because of the complexity, variability and randomness of socio-economic activities. Therefore, it is of practical significance to study random input- output model by using random-variable-sum theory. Taking direct consumption coefficient and final demand as the precondition of normal random variables, this paper probes into the random input-output model and derives the equations that satisfy the total output of all departments.
