The Role of Institutional and Innovation Ecosystem in Moderating the Impact of Green Practices on Export Performance: Evidence from European Countries

As global merchandise exports reached $22 trillion in 2023 and environmental standards have become increasingly stringent, understanding how green practices influence export competitiveness has become critically important. Although existing research documents positive associations between environmental practices and trade outcomes, the conditions that enhance or constrain these relationships remain underexplored, particularly at the macro level across different export performance segments. Using panel data from 30 European countries for the period 2012–2022, this study examines how institutional and innovation ecosystem factors moderate the relationship between green practices and export performance. Employing panel quantile regression alongside conventional panel methods, we investigate whether regulatory quality, research and development expenditure, and financial market development influence the export benefits derived from ISO14001 certification and environmental patents. Our baseline findings reveal that both environmental management systems and green innovations show positive associations with exports, with ISO14001 certification demonstrating stronger effects in countries with lower export volumes. Notably, regulatory quality and financial market development significantly amplify the export benefits of environmental management systems. However, robustness checks employing instrumental variable estimation and System GMM to address potential endogeneity reveal that these direct effects weaken substantially when reverse causality is explicitly addressed, though point estimates remain consistently positive. These results suggest that while positive associations between environmental practices and export performance appear robust across multiple specifications, establishing definitive causal effects requires cautious interpretation and future quasi-experimental research. The findings highlight the importance of coordinated policy approaches integrating environmental, financial market, and regulatory dimensions, while underscoring that institutional moderators may provide more robust insights than direct effect estimates for understanding how environmental practices enhance competitiveness in international markets.
