The study has as main objective to assess (quantitatively as well as qualitatively) the way in which the governmental fiscal sectoral block could be positioned relatively to the other sectoral blocks of the national economy, within a macroeconomic model. To this end, some logical criteria are introduced and, based on them ten sectoral blocks of the national economy are identified and described. Then, all the economic flows (in money expression) among the fiscal block and the other nine sectoral blocks are identified and systematized, as inputs or outputs. Finally, a double entrance matrix is elaborated in order to highlight all these economic flows and to put the bases to elaborate, in future studies, even an inter-sectoral blocks balance, in an analogous way with the elaboration of the well-known Leontief inter-branch balance.

Macroeconomic models of behaviour description is based mainly on sectoral blocks from a perspective of economic flows (real and nominal) not directly related to national accounts, but rather economic markets. This makes the analyzes or predictions made on the basis of these models (either financial planning or behaviour) to be "valid" in terms of markets, but not to calibrate the national accounts or vice versa. The project intends therefore to achieve a synthesis between these two types of modelling, so both markets and national accounts to be taken into account when designing the model and its use. This article is only part of a project intended toachieve a synthesis between these two types of modeling.

Based on four logical criteria of classification, which should act together, we propose a general classification of sectoral blocks that can be associated to a national economy. Establishing sectoral blocks economic and / or institutional action must follow homogeneity criterion actions performed within that sectoral block. We proposed a structure of economic activity at national level sector consists of ten sectoral blocks. Then, we are identified and described all the economic flows (in money expression) among the fiscal block andthe other nine sectoral blocks. The purpose of our future research is to build a model based behavioural macroeconomic interactions that occur between economic markets, sectoral blocks and national accounts. Finally these interactions will be quantified in the form of equations.
