The Limiting Characteristics of A Sort of Macroeconomic Model

We presented a sort of macroeconomic model by use of input—output analysis method, and discussed the relations and limiting characteristics among output, input and consumption, when the programming period is long enough, and explain that Initial inveatment mustn′t be the positive characteristic vector of direct consumption coefficient matrix, and the output, input and consumption all tend to the positive characteristic vector of direct consumption coefficient matrix, the system grows with stable state, and presents Turnpike character, under the conditioin that there is no crisis in the system.
