An Analysis of Gray Dynamic Input-Output Model Based on Variable Structure Control

Considering the impact of the objective environment on the economic system, this article introduces gray elements to a dynamic input-output model which is based on variable structure control, and proposes the methods of determining the important parameters of the model. This model can reveal the relationship between propensity to consume, propensity to invest, the structure of consumption and investment, and industrial structure. It has great significance to adjustment and optimization of industrial structure.
