Assessing Income, Industrial Structure and Urbanization Impacts on Carbon Kuznets Curves in Beijing Area
Abstract:
The Carbon Kuznets curves (CKC) were widely used to forecast the future trend and turning point of carbon emission. But some key factors which influence the carbon emission a lot were not taken into consideration. In this paper, industrial structure and urbanization were added as linear factors in the CKC and Beijing area was the research object. Three expansion equations, named industrial structure CKC (CKC-S), urbanization CKC (CKC-P) and double factors CKC (CKC-SP) , were put forward. The data was from 1980 to 2009. Finding indicated that an invented U-shaped relationship exists with GDP/capita and carbon emission made by per capita. The change of industrial structure and urbanization could affect the trend and turning point of carbon emission. For Beijing area, carbon emission made by per capita would reach the turning point after 5.5 years according to the CKC-SP, and the carbon emission made by per capita was about 2.43t. These Expansion equations also showed that more secondary industry output and more urban population would lead to a higher turning point. For Beijing area, the adjustment of industrial structure has little affection on emission reduction, other measures such as improving energy efficiency and reducing the emission from consumption activities should be taken to achieve the emission reduction targets.
