Assessing the Impact of Technological Innovations and Trade Openness on Environmental Sustainability: An Empirical Study of South Asian Economies Using Panel ARDL Approach

Abstract

This study examines the major factors that influence environmental sustainability over a 20-year period (2000–2020) in the four South Asian economies. In this study, two methods of estimation including the Pool Mean Group (PMG) estimator and the panel autoregressive distributed lag (ARDL) approach are used. The findings explore that trade openness, energy consumption, and economic expansion have a long-term positive and considerable impact on environmental deterioration, conversely technical innovation has a long-term negative impact on the environment. In short run scenario, trade openness and energy usage have significant and favourable effects on environmental degradation, whereas the economic growth and technological advancement have had a substantial negative influence on the environment. From this study, the policy makers provide the direction to the government by incentivizing technology, enforcing energy-efficient laws, promoting renewable energy, aligning trade policies with environmental goals, and enhancing regional cooperation. In order to improve South Asian environmental sustainable policies, future research should examine energy-trade-growth-technology by employing advanced techniques, and prioritizing innovation.
