Abstract
This study examines Kazakhstan's economic growth from 2013 to 2023, focusing on the impact of energy depletion and gross national expenditure on GDP. Using correlation, regression, and dispersion analyses, the research reveals that gross national expenditure is the most significant driver of GDP, demonstrating strong positive relationships and consistent contributions. In contrast, while positively correlated with GDP, energy depletion shows moderate variability and a lesser overall impact. These findings emphasise the importance of reducing economic reliance on resource depletion and fostering domestic economic activities to ensure sustainable and resilient growth. The study provides actionable insights for policymakers to balance resource dependency with diversification efforts and strategic investment.
