Abstract: Cette étude vise à tester empiriquement la relation entre la diversification des revenus et le pouvoir de marché ainsi que la relation entre le pouvoir de marché, la diversification des revenus et la stabilité financière bancaire. En se basant sur une base de données de 10 banques commerciales Tunisiennes sur la période allant de 1990 à 2013, on démontre qu'il existe une relation significative et positive entre le pouvoir de marché et la stabilité financière. Ceci vient renforcer les résultats des recherches antérieures portant sur différents systèmes bancaires dans plusieurs pays.This study analyses the relationship between income diversification and market power and also studies the relationship between market power, income diversification and bank financial stability. Based on a database of 10 Tunisian commercial banks over the period from 1990 to 2013, our results show that there is a significant positive correlation between market power and financial stability. These results support the results of previous researches on various banking systems in several countries.
