Abstract: Taking the discharge amount of main pollutants as the index of environmental pollution level, and with GDP per capita as the index of economic growth, this paper analyzed the relationship between these two indices in Beijing during 1992-2008, and established a computation model to approach the effects of economic growth in Beijing on the environmental quality of the city. The results showed that the environmental Kuznets curve (EKC) could be used for describing the relationship between the GDP per capita and the discharge amount of main pollutants in Beijing during 1992-2008. At present, the discharge amount of the pollutants such as industrial wastes, industrial COD, oils, and industrial dusts, etc. in Beijing had a significant decreasing trend with the growth of GDP per capita, indicating that the discharge of major pollutants in the city had crossed the inflection point, possibly owing to the efficient environmental policy and huge environmental investment by the central and municipal governments. It was suggested that at the time of developing economy, it should be stressed to further adjust industrial structure, reduce industrial pollutants discharge, and strengthen the formulation and implementation of environmental management policies. Only by doing these, the economic growth and environmental quality in Beijing could be cooperatively and sustainably improved.
