The effects of high technology export and per capita income on carbon emission: An investigation on G20 countries

We aim to investigate the impact of per capita income and high technology product export on CO2 emissions in G20 countries (except Russia) from 1992 to 2014 via panel data analysis. We applied random coefficient panel regression method to capture the heterogeneity of the G20 countries. The findings indicate that per capita income has stronger impact on CO2 emission level in developing countries whereas high technology export has stronger impact on CO2 emission level in developed countries. We interpret this result in the way that developing countries increase their CO2 emissions through increased income and consumption whereas developed countries do so via production and export.
