Innovation for Sustainability: How Green and Financial Innovation Shape Green Growth

Abstract

In today's world, sustainability strategies play a critical role in the transformation of global economies and industries. Green Economic Growth (GEG), which prioritizes environmental factors, is gaining increasing importance. Financial and green innovation are identified as the main driving forces behind GEG. However, research on the effects of these factors in OECD countries remains limited, and existing findings often show inconsistencies regarding the direction and magnitude of these effects. This study aims to comprehensively examine the impact of financial and green innovation on GEG in OECD countries. Using annual data from 15 OECD countries for the period 1996–2021, panel data techniques are applied. Cointegration tests are conducted to determine the presence of long-run relationships among the variables. Subsequently, long-run coefficients are estimated using the panel quantile regression method. The robustness of the findings is tested through OLS and fixed effects models. Additionally, causality tests are employed to explore the directional relationships between the variables. The results indicate that green innovation has a positive long-run effect on GEG, whereas financial innovation exerts a negative impact. Causality tests reveal bidirectional relationships among all variables. Policy recommendations include the promotion of green bonds and sustainable finance instruments, support for green investments through regulations that take environmental risks into account, and the expansion of access to green projects via technologies such as blockchain-based carbon markets. This research provides valuable insights for policymakers in designing more effective strategies to foster sustainable economic growth.
