Abstract
<jats:p>This article analyzes the mechanisms of using financial instruments in ensuring regional development and their economic effectiveness. The study comparatively studies the models of financing regional development based on the experience of the European Union countries, in particular Poland and Turkey. The article analyzes the institutional foundations of financial instruments, revolving financing mechanisms, the activities of regional development agencies and the economic results of financing systems implemented on the basis of public-private partnerships. According to the results of the analysis, it was found that the effectiveness of financial instruments in regional development depends on their repeatability, targeting and the level of institutional coordination. Also, based on the experience of Poland and Turkey, the importance of using effective models of regional financing, in particular, revolving funds, regional development agencies and innovative financial instruments (venture funds, "green" bonds, sukuk) is substantiated. The results of the study allow us to develop practical recommendations for improving regional development financing mechanisms in Uzbekistan, increasing the economic potential of regions and stimulating investment activity.</jats:p>
