一、问题的提出投入产出分析法,是美国著名经济学家Wassily W Leontief率先提出的定量经济分析方法。该方法利用数学方法和电子计算机来研究各种经济活动的投入与产出之间的数量关系,科学的预测、分析和安排经济关系、结构、计划、管理以及成本价格等经济活动。七十年代以来,世界各国来自经济学、数学、控制理论和电子计算机领域的学者互相配合,使投入产出基础理论,动态投入产出模型,投入产出优化模型等课题的研究取得了显著 First, the question put forward Input-output analysis, is the United States leading economist Wassily W Leontief first proposed quantitative economic analysis. The method uses mathematical methods and electronic computers to study the quantitative relationship between inputs and outputs of various economic activities, and to predict, analyze and arrange economic activities such as economic relations, structure, planning, management and cost price scientifically. Since the 1970s, scholars from all fields of economics, mathematics, control theory and computer science have cooperated with each other and made remarkable achievements in such topics as input-output basic theory, dynamic input-output model and input-output optimization model
