| dc.description.abstract | The Environmental Kuznets Curve（EKC）describes a relationship between economic growth and environmental quality.In this paper, we apply energy and emission data that published by International Energy Agency（IEA）to analyse CO2 emission variation in Taiwan, Japan and Korea from 1971 to 2005.
By using CO2 intensity for environmental pressure index, GDP per captia for economic growth index and other exogenous variables,for instance, energy structure, industry structure, crude oil price, energy productivity and trade effect to show the pattern of EKC in Taiwan, Japan and Korea.
The econometric results lead to two conclusions. Firstly, the relationship between CO2 intensity and GDP per captia in Taiwan and Korea is U-shape. The turning point in Taiwan is 7,300 and in Korea is 15,934（US dollar by PPP）. Secondly, the EKC pattern in Japan is monotonically decreasing linear relationship.
The reasons for U-shape EKC in Taiwan and Korea are as follows. First of all, both countries are export-oriented. Secondly, the power price in Taiwan and Korea is lower than that in Japan. Thirdly, the industry structure in Korea is industry-oriented and Taiwan too depends on coal using. Finally, the ratio of electricity output by natural gas and nuclear in Taiwan is lower than Japan and Korea.
In short, we suggest some measures to improve relationship between CO2 intensity and GDP per captia. First, to develop diversity energy supply strategies. Second, by rising energy price in order to reduce energy use. Third, to enhance the ratio of electricity output by nuclear. Forth, to maintain the growth of service industry and lower the development of high energy intensity industry. Finally, to strengthen energy efficiency in transport sectors. | en_US |
