This article analyzes the development of the fisheries sector in the Republic of Uzbekistan, particularly in the Syrdarya region, using econometric methods. The study highlights the role of fish products in food security, public health, and economic diversification. The analysis is based on statistical data from 2010 to 2023 and evaluated using autocorrelation and the Durbin-Watson test. Forecast values for the next five years are developed, and practical conclusions are presented to further enhance the fisheries sector.

This scientific study provides an in-depth analysis of the factors influencing the management efficiency of free economic zones (FEZs) in the Republic of Uzbekistan, assessing their contribution to socio-economic development using mathematical modeling. Using the Jizzakh Free Economic Zone as a case study, the research identifies key factors affecting production volume from 2015 to 2024 — namely, foreign investment and employment levels. The study employs the Cobb-Douglas production function to construct a classical linear regression model, along with an autoregressive (AR) model, correlation-regression analysis, and evaluation through Fisher’s criterion, Student’s t-test, and the Durbin-Watson statistic.
