Going green across boundaries: spatial effects of environmental policies on tourism flows

This study investigates the relationship between environmental sustainability policies and tourism flows across Italian provinces using a spatial Durbin error model (SDEM) within a gravity framework. By incorporating both public and corporate environmental initiatives, the analysis highlights the direct and spatial spillover effects of sustainability measures on tourism demand. The findings indicate that corporate-led initiatives, such as ecocertifications and green investments, exert a stronger direct influence on tourism flows compared to public measures, underscoring the visibility and immediate impact of private sector actions. However, both types of initiatives generate significant positive spatial spillovers, suggesting that sustainability efforts extend beyond local boundaries. These results demonstrate the interconnected nature of regional tourism systems and emphasise the critical role of coordinated sustainability policies in fostering tourism growth while promoting environmental protection. By addressing the spatial interdependencies of tourism flows and sustainability practices, this research provides valuable insights for policymakers and stakeholders seeking to improve sustainable tourism development at regional and national levels.
