The input-output method is a quantitative analysis method that studies the interdependence between inputs and outputs in various parts of the economic system (national economy, regional economy, sector economy, companies or enterprise economic units). The basic content of the input-output method is to prepare the input-output table, establish the corresponding linear algebraic equation system, comprehensively analyze and determine the intricate links between various sectors of the national economy, and analyze the important macroeconomic proportional relationship and industrial structure and other basic issues.
The input-output method is characterized by starting from the viewpoint that the national economy is an organic whole, and reflecting the formation process of product value and the movement process of use value at the same time. On the one hand, it reflects the technical and economic links of various sectors of the national economy, on the other hand, it reflects the quantitative links between the total social products and intermediate and final products, combining mathematical methods and electronic computing technology.

What is the "input-output method" in the statistical method?
Input output method
The method of studying and analyzing the quantity dependence relationship between production and consumption of products among various sectors of the national economy, also known as input-output analysis or balanced economic mathematical model among sectors, is an important modeling method of system engineering. Each production department needs to purchase products and pay service fees from other production departments, and also produce products and provide services for other departments. In order to study the quantitative dependence of input and output, various economic activities can be expressed in a specially designed input-output table, thus providing a concise and systematic structural model for studying the entire economic activities of a country or region.
Concept of output method
The input-output method, as a scientific method, is a quantitative analysis method to study the interdependence between inputs and outputs in various parts of the economic system.
The input-output method is a method that arranges a series of internal departments' input sources and output directions into a crisscross input-output table within a certain period of time, establishes a mathematical model based on this table, calculates the consumption coefficient, and conducts economic analysis and prediction.
What is the opposite principle of input-output method
Factor endowment theory.) Leontief's anti theory masterpiece Input Output Economics and the development of international trade theory use the input-output analysis method to analyze the structure of American import and export trade. Contrary to the theory of factor endowments, that is, the United States exports mainly labor-intensive products, while imports are capital intensive products. The input-output method is a method that arranges a series of internal departments into a crisscross input-output table with input purchase sources and output sales directions within a certain period of time, establishes a mathematical model based on this table, calculates the consumption coefficient, and conducts economic analysis and prediction.
