Özet
This study examines the determinants of renewable energy supply share (RES) in a balanced panel of 17 countries (1995– 2021), focusing on green technology innovations (GTI), economic growth (EG), and energy tax (ET). The analysis accounts for heterogeneity, common shocks, and dynamic adjustment by combining two-way fixed effects with dependence-robust and dynamic common correlated effects (CCE) estimators using Driscoll–Kraay inference. The results show strong persistence in RES and a robust positive association between GTI and RES in the preferred commonfactor framework, while the average effects of EG and ET are weaker and model-sensitive. Dumitrescu–Hurlin panel causality tests indicate feedback between RES and EG and bidirectional linkages between RES and ET at the level, whereas innovation dynamics are asymmetric. Overall, the evidence supports innovation-centered transition strategies and emphasizes evaluating policy instruments over multi-year horizons given strong persistence and cross-country heterogeneity.
