전력 생산 에너지 비중 구조에 따른주요 국가별 효율성 비교

초록

In this research, the efficiency of generating electricity for major OECD countries and non-OECD countries was studied. DEA and Post-DEA methods were used to analyze efficiency of generating electricity. Under these research methods, it figured out electric efficiency of each of countries and phased benchmarking objects as well as the distinctive feature of efficient countries by electricity production sources’ composition. With these results, this paper suggested a policy about the composition of electricity production sources in terms of efficiency. The overall average efficiency was 0.883 and 5 countries of all 19 countries were the most efficient counties in CCR model. On the other hand, there were 12 countries which were the most efficient countries in BCC model with the overall average efficiency 0.951. In tier analysis, it divided each of countries into 3 groups. They are 5 countries in Tier 1 groups including of Korea, 7 countries in Tier 2 groups. and rest of countries that did not be included in these Tier groups. This result could give information about the way of benchmarking to make better electricity efficient countries. Also, an energy composition of the efficient countries was found. There is distinctive feature that electricity efficiency was depended on how much the endowed resources were held. Most of the efficient countries using fossil energy sources had sufficient endowed resources. Otherwise, using nuclear energy was recommended in terms of electric energy efficiency. Because Korea is one of the most efficient country even though does not have sufficient endowed resources, Korea should keep their generating policy using nuclear energy to generate electricity efficiently.
