ABSTRACT

This study identified substitutional relationships among energy uses in metropolitan cities and provinces from 2013 to 2016, and used the Logarithmic Mean Divisia Index (LMDI) method to grasp the degree of contribution of energy sources, GRDP, and population changes by reduction in oil prices. As a result, the emissions of particulate matter(PM10) and fine particulate matter(PM2.5) were shown to be affected by the energy intensity (EI), energy concentration (EC), economic output (EO), population change (POP), and total energy intensity (ETI). By energy source, since the EC was large in the order of oil, coal, electricity, and gas, the EI was analyzed to contribute to the emission of PM10 and PM2.5 in the order of gas, electricity, coal, and oil. In addition, it was found that EO rather than POP contributed to the emissions of PM10 and PM2.5, and also it was found to contribute more in provinces than metropolitan cities. In addition, considering the change in demand among energy sources due to the recent reduction in oil price, substitutional relationships among oil and other energy sources were identified, and LMDI method was extended by applying the relationship among energy sources, GRDP, and population change from the VAR model. As a result of applying reduction in oil price, the EC of oil increased while others decreased. Therefore, the EI of oil to PM10 and PM2.5 was decreased, while the EI of coal and gas of substitutes except electricity were decreased. In addition, it shown that the increase in demand due to the reduction in oil prices increased the ETI, while the contribution ratio of EO and POP was reduced.
