Some Basic Studies On The Solvability Theorem Of The Conditional Input And Output Equation

Based on the classical Leontief input and output model, this paper introduces a kind of conditional Leontief model and the corresponding input and output equation which is more suitable to the production and management of the enterprise. It also puts forward the related solvability problem. By applying important theorems in nonlinear analysis, some solvability results about this kind of conditional input and output equation are obtained under certain conditions.This paper is separated into five chapters. In the first chapter, this paper introduces the conditional Leontief model and the corresponding conditional input and output equation. From Chapter Two to Chapter Four, we study the conditional input and output equation and obtain the solvability theorem under certain conditions. The last part is mainly about the multi-valued conditional input and output equation.
