Abstract
The article examines the key factors influencing the efficiency and attractiveness of regional investment projects in Uzbekistan, with particular emphasis on institutional conditions, financial mechanisms, and the role of Youth Industrial and Entrepreneurship Zones (YIEZs). The study explores the conceptual foundations of the investment environment, investment climate, and investment attractiveness, drawing on international and national theoretical perspectives. Using analytical and comparative methods, the research evaluates existing barriers to investment efficiency, including infrastructure gaps, regulatory inconsistencies, high project costs, and limited investor protection. Special attention is given to the functioning of YIEZs as a policy instrument aimed at promoting youth entrepreneurship and stimulating regional economic development. Based on statistical data and project implementation reports, the article assesses current outcomes in YIEZs and identifies structural challenges that affect project performance. The study proposes an improved financial mechanism for leasing production facilities to young entrepreneurs, aiming to reduce entry barriers and enhance project sustainability. The research concludes that strengthening institutional coordination, expanding financial incentives, and improving infrastructure are essential for increasing investment project efficiency and creating a more competitive regional investment environment in Uzbekistan.
