Research Of Some Models On Input-Output

Firstly, we discuss the basic model without stochastic factors. We discuss the input-output model without consumption and the model with consumption. And we mainly study the affect of consumption on economy. We mainly apply matrix to the model, and get some good answer.Secondly, we study the affect of some stochastic factors in the function of economy. We study the role of stochastic consumption in socialist market economy. In the model, we mainly apply probability and stochastic process.Finally, the paper gives out the work that we must solve in future.
