摘　　要：本文引入了一类基于企业消耗与市场需求的条件投入产出方程,在适当的基本假设下,用非线性分析方法对这类方程分别包含存在性,连续性及满射性的可解性问题作了初步研究.由此获得本文的主要结果并给出相应的经济解释.This paper introduces a class of conditional input-output equation based on the enterprise's consuming and the demand of the market. Under some proper basic assumptions, primary researches by means of nonlinear analysis methods are devoted to the solvability question respectively including the existence, continuous dependence, and surjection, from which the authors obtain the main theorem and give some corresponding economic explanations.
