The service sector is one of the key sectors of the modern economy and a determining factor of sustainable economic growth. In the Republic of Uzbekistan, services generate nearly half of gross domestic product and provide employment for a significant share of the population. Despite the high growth rates of service output, the incomes of enterprises in this sector remain constrained due to low labor productivity, regional disparities, infrastructure limitations, and shortages of qualified personnel. The purpose of this article is to analyze the dynamics of service sector enterprise incomes, identify the factors shaping their formation, and develop practical ways to increase incomes based on national and international experience. The study employs methods of statistical analysis, comparative analysis, and generalization. The results indicate that digitalization, human capital development, and liberalization of service markets are key determinants of enterprise income growth.
