Digital Transformation and Economic Growth in Central Asia: A Panel ARDL Approach

This study examines the short- and long-run effects of digital transformation on economic growth in five Central Asian economies (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan) over 2000-2024. A composite Digital Transformation Index (DTI) is constructed by principal component analysis from internet penetration, mobile cellular subscriptions, fixed broadband subscriptions and ICT service exports. Given cross-sectional dependence, mixed orders of integration and heterogeneous country dynamics, the analysis applies second-generation panel unit root tests (CIPS), Westerlund cointegration tests and the panel autoregressive distributed lag (ARDL) framework estimated by Pooled Mean Group (PMG), Mean Group (MG) and Dynamic Fixed Effects (DFE) estimators. The model controls for physical capital, human capital, trade openness and inflation. [Insert main finding after estimation: e.g., a 1% increase in DTI raises real GDP per capita by X% in the long run, while short-run effects are heterogeneous across countries.] The results support policies that combine digital infrastructure investment with digital skills development and regional digital market integration.
