摘要：The links between the branches of economy are realized in concrete terms, there being elements to be
studied and analysed. Thus, within the national economy there is intermediate consumption that specifies
the consumption of a branch of all other branches. For this, we calculate intermediate consumption
technology coefficients that are used to determine the results of the national economy.
For this the input-output table was created and also the balance connection between branches which at
the macroeconomic level is a complex model that provides the necessary elements of the calculation and
analysis of economic performance.
In order to perform such an analysis it is important to determine how branches of national economy are
aggregated. Aggregation of branches of national economy is the first step to study the links between them.
The number of branches and the concentration requirements are subordinated to identifying links and
proportions that are achieved.
In this article, the meaning of a homogeneous branch is reduced to goods and services that meet certain
criteria, according to international standards.
For the first time, the model was used in the United States, with the scientific support input-output table
of Leontief. In Romania, this input-output system is used and complemented that gives an additional
possibility to analyze and study the national economy.
