Abstract
In order to measure the economic activity, it is usual to rely on the national
accounts data, which in principle, follows the international recommendations
written in the System of National Accounts, SNA. As a way to obtain one more
instrument to analyse the economic activity of a country and also which allows
for police impact analysis, the social accounting matrix, SAM, is the one that
provides the answer. For this paper, we propose it in its reduced form, and the
data is regarded the year 2016. The essence of a SAM in this work is to be
found by the transactions and transfers between different institutional sectors.

Keywords
Economic activity; social accounting matrix; national accounts

The social accounting matrix, SAM, is a matrix representation of the income
circular flow. It captures all the real transfers among industries and institutional
sectors namely, non-financial corporations, financial corporations,
government, households and non-profit institutions serving households and
its interaction with the rest of the world sector. With a SAM it is possible to
distinguish the commodities, which in broad terms are called goods and
services, from the industries, production factors and institutional sectors. A
reduced SAM that we are proposing for Mozambique, will help in quality
control in the national accounts, as long as they are relatively weak and
incomplete. The designation reduced is due to the fact that it will be presented
in aggregated terms; the details not going to be at the level of institutional
units such as enterprises. The base for the construction of a SAM is the
Economic Integrated Accounting that represents a sequence of economic
accounts, starting from the current accounts ending with accumulation
accounts. This sequence belongs to the standard SNA, is produced by the
national accounts and allows for a comprehensive description of an economy
emphasizing the distributives aspects. National accounts constitute a product
of official statistics so that accuracy in its compilation is required. In fact, the
economic activity, the main source of income and wealth is the origin of all
flows that composes the network links that is established in the economy. It
requires intermediate inputs that are used during the productive process in
