基于指数分布的投入产出模型

Exponential distribution-based input-output model

用随机模型来描述经济系统的变化情况,是符合实际的.为此,运用随机变量和的分布理论,在直接消耗系数和最终需求为指数型随机变量的条件下,导出了n个部门的投入产出模型的确定性等价方程.

In consideration of the fact that the stochastic model can reflect the reality of economic phenomena, the theory of sum distribution of random variables is adopted in this paper. Under the assumption that the coefficients of direct consumption and final demand are random variables with the exponential distribution, the deterministic equivalent equations for input-output model of n departments are derived.
