Abstract: The essence of an economic system programming is virtually a problem of optimal control of a discrete dynamic system. Under this conditions, the initial state of the system is known,the final state is almost fixed, and there are time delays between the inputs and outputs of the system.This type of problem can be solved by LQ (Linear Quadratic) optimal control models. The system dynamics model, the system input output analysis model and the multiple goal programming model are three wellknown typical economics analysing models. This artical puts them together and originally combines them to an organic whole to solve the above problem.Compared with the LQ optimal control model, the integrated model has many advantages.
