Asymmetric and symmetric responses of the environmental performance on tourism industry : a case study of D-8 countries

Abstract

This study explores the asymmetric and symmetric responses of the environmental performance on tourism industry in the context of D-8 countries. While the tourism sector significantly contributes to economic growth, its environmental impact, particularly in developing countries like those in the D-8 group, remains underexplored. Existing research often overlooks the nonlinear and complex relationships between environmental performance and tourism activities, creating a significant gap in literature. Addressing this gap, the study aims to analyze the short-run and long-run symmetric and asymmetric impacts of environmental performance on the tourism industry within D-8 countries using advanced econometric models such as ARDL and NARDL. Employing a quantitative approach, the research utilizes panel data from 2008 to 2024, sourced from reputable institutions like the World Data Bank, World Travel and Tourism Council (WTTC) and Yale Center for Environmental Law & Policy. By capturing both symmetric and asymmetric relationships, the study provides deeper insights into the dynamic interplay between environmental performance and tourism. The findings are expected to reveal the differential impacts of positive and negative shocks in environmental performance on tourism trends, offering actionable insights for policymakers. It is anticipated that the study will propose strategies for integrating green tourism practices, developing energy-efficient infrastructure, and adopting international environmental standards to foster sustainable tourism while mitigating ecological degradation in D-8 countries.
