Abstract: The article aims to analyze the evolution of market power, expressed by various indicators of economic concentration in the retail sector (NACE 2 figures) in the period 2012-2021. The results show that there is a general trend of increasing the level of economic concentration expressed by the Herfindahl-Hirschman index cumulated at NACE level 2 digits, obtained by weighting the turnover of the sub-sector of activity (NACE 4 digits) in the total turnover of the retail sector. Proxy indicators, such as the evolution of the share of employees in companies with over 50 employees in total employees or the evolution of the average/median of the real turnover in the period 2012-2021, reinforce the above conclusion, but in the structure, the relationship is relatively balanced between the number of industries for which the degree of concentration increases and the number of industries for which the degree of concentration decreases. And the analysis carried out from the perspective of the correlation coefficient between the HHI index and the profit rate indicates a relatively balanced distribution between negative and positive correlations at industry level, the intensity of positive correlations being higher.
