이산화탄소 배출의 원인 조건으로서 사회경제적 요인, 기술적 요인의 역할에 관한 연구 : 퍼지셋 질적 비교 분석을 활용한 OECD 국가 비교 분석

The study analyzes an impact of economic factor(i.e. economic growth, energy usage, trade openness), technological factor - represented by technological innovation - on carbon dioxide (CO2) emission at the country level. Based on data from OECD countries, we investigate a causal configurations beyond the exclusive leverage of those factors in order to identify the possible combinations for unifinality using fuzzy-set qualitative comparative analysis (fsQCA). Our findings show that the main condition for CO2 emission is ‘energy use’, indicating this condition usually exists in high emitter countries. Notably, an impact of ‘international trade openness’ on environmental performance can be varied in accordance with a condition of combinations. Also, our results confirm that an environmental technological innovation as a technological factor by combining with economic factors is positively associated with a high level of CO2 emission. This could implicate that high levels of technological innovation fails to compensate for the environmental impact of other conditions or sufficiently diffuse into a private market, leading to a negative environmental performance.
