Tóm tắt

The research investigates the interactions between ecological sustainability and green technologies in Vietnam at different time and frequency dimensions from 1992 to 2019. This study investigates these correlations and their frequency domains by employing innovative multivariate wavelet analysis techniques. The multiple coherencies between green technologies and ecological sustainability suggest one cycle was placed at low frequencies (periodicity of approximately 5-14 years) and spanned from 1996 to 1998. Two significant coexisted cycles at low frequencies were from 2001 to 2004 and 2001 to 2009. The three additional cycles were situated at high frequencies (periodicity of approximately 1-5 years). These cycles ran from 2004 to 2006, 2014 to 2016, and another cycle from 2017 to 2019. The partial wavelet coherency of green technology growth and CO
