In Section II, we survey literatures. In Section III.1, we use some indicators such as
the number of motor vehicles and cement production representing environmental
pressure to compare these indicators with economic activity level. It will show the
increasing environmental pressure along the economic growth path in South Korea. In
Section III.2, using time series data of environmental quality indicators, environmental
quality is analysed to see how it changes during the process of economic growth. This section investigates the hypothesis of the inverted U-shape curve for South Korea.
Section IV summarises the results.
