ECONOMETRIC ANALYSIS OF THE EFFECTIVE USE OF INVESTMENTS IN THE DEVELOPMENT OF THE REPUBLIC'S ECONOMY

Abstract

This paper comprehensively examines the theoretical and practical aspects of the efficient use of investments in the development of the national economy based on an econometric approach. The study utilizes macroeconomic data for the period 2000–2024 to conduct an in-depth analysis of the impact of investment volume, employment level, and export volume on Gross Domestic Product (GDP). The methodological framework includes correlation analysis, construction of a multiple regression model, evaluation of parameter significance using t-statistics, assessment of overall model adequacy through the F-test, and testing for autocorrelation using the Durbin–Watson statistic. All econometric computations and model estimations were carried out using the modern statistical software environment R Studio. The empirical results demonstrate that investments have a strong positive and statistically significant effect on economic growth, as measured by GDP. Based on the findings, a set of practical recommendations has been developed aimed at improving the efficiency of investment utilization, optimizing their allocation across economic sectors, and enhancing investment policy.
