Due to China's rapid economic growth over the past few decades and its subsequent environmental deterioration, much attention has been focused on whether or not the country's development is sustainable and when and how the country will improve environmental conditions. The Environmental Kuznets Curve (EKC) hypothesizes that environment quality deteriorates with the increase of per capita income at the early stage of economic growth and gradually improves when the country reaches to a certain level of affluence. This paper tests the availability of EKC in China, and also studies the effects of economic structural change, international trade, FDI and governmental abatement effort on environmental pollutions in China.
