Abstract

ASEAN (Association of Southeast Asian Nations) has contributed numerous carbon emissions during the phase of industrialization. This study mainly compares the different effects of export and import on CO₂ emissions across 7 ASEAN countries over 1990-2017. In addition, we investigate how technological innovation affects carbon emissions. Stationary tests are conducted through cross section dependence, unit root of panel data, and Westerlund cointegration. The results of panel quantile regression show that export and import both have adverse effects on CO₂ emissions. EKC is valid in these countries. Moreover, population size and energy intensity increase carbon emissions. In particular, technology innovation significantly reduces carbon emissions by augmenting energy efficiency. It is important to improve eco-innovation, and expand knowledge-intensive industries in ASEAN countries.
