ICT가 CO2 배출에 미치는 영향: 경제성장, 무역개방성, 금융발전과의 연관관계하에서 분석

Abstract

This study investigated the impact of information and communication technology (ICT), trade openness, financial development, and economic growth on CO2 emissions in Korea from 1990 to 2016. The cointegration relationship of the variables was confirmed by an autoregressive distributed lag (ARDL) bounds test. In the long-run, economic growth was statistically significant factor in the increase in CO2 emissions, while other factors, as well as ICT, did not significant factors in the changes in CO2 emissions. In the long-run, a link between economic growth and CO2 emissions has been confirmed, but other factors, including ICT, have not been able to confirm the link between CO2 emissions in the long-run. Meanwhile, in the short-run, economic growth and ICT increased CO2 emissions, and financial development led to a decrease in CO2 emissions. Trade openness did not have a significant effect on CO2 emissions in the short-run as in the long-run. In particular, ICT did not contribute to the reduction of CO2 emissions in the short-run as well as the long-run. In order to induce CO2 mitigation through ICT, the development and deployment of technology that efficiently save energy by using ICT should be further promoted.
