Résumé:
This research paper aims to study the concept of competitive theory through the use of macroeconomic variables relying on statistical techniques, standard and economic, to measure economic and development performance within the various economic sectors, within a sample of countries, and it is considered a comparative study between them where they represent the same characteristics and advantages of These countries. The results of the study showed that Algeria is less competitive compared to Indonesia and Saudi Arabia, and this is due to the fact that the study variables do not affect the national raw income, especially the value added variable for the industry sector, as the latter suffers from several problems.
