Are regional public budgets associated with renewable energy development? Evidence from Ukraine

Анотація

Type of the article: Research ArticleAbstractThe growing importance of renewable energy in ensuring energy security and sustainable development has increased attention to the role of public finance, particularly at the regional level. This study aims to assess whether different categories of regional public expenditure are associated with renewable energy development in Ukraine, distinguishing between installed capacity and electricity generation. The analysis is based on a balanced panel dataset for 25 Ukrainian regions over 2018–2021 and applies two-way fixed effects models with lagged specifications and Driscoll–Kraay standard errors. The results show that expenditures on electric transport exhibit the strongest positive association with installed renewable energy capacity (β ≈ 0.078, p < 0.001), followed by SME support (β ≈ 0.025, p < 0.001), other environmental activities (β ≈ 0.017, p < 0.001), and natural resource management (β ≈ 0.013, p < 0.001). In contrast, most general economic expenditures are not statistically significant, suggesting that these expenditure categories are not statistically associated with higher renewable energy development within the analyzed period. For renewable electricity production, contributions to the statutory capital of enterprises are positively associated (β ≈ 0.006, p < 0.05), while co-financing of investment projects is negatively associated (β ≈ −0.027, p < 0.001), reflecting implementation lags. Additionally, capital investments in environmental protection are negatively associated with renewable electricity production (β ≈ −0.072, p < 0.001), suggesting that installed capacity expansion differs from renewable electricity production.AcknowledgmentThe authors acknowledge funding from the Swiss National Science Foundation (SNSF) [Grant No. IZURZ1_224119].
