Study On The Relationship Between Economic Growth And Emission Of Main Pollutants In Anhui Province

With the acceleration of the process of industrialization,worldwide deterioration of environmental quality has become concerned issue. Mounting public concern over environmental issues has sparked efforts to understand more clearly the reasons for environmental degradation. The environmental effects of economic growth have been receiving increasing attention of scholars in recent years and the linkage of environment with economic growth evoked much discussion .Can economic growth be part of the solution rather than the cause of environmental problem? This has been the primary motivation for empirical studies on EKC.It shows that the study on EKC has profound significance to realize the relationship between economic growth and environment and assess the existing environmental policies. Mathematical relationship between economic growth and emission of main pollutants in Anhui province has been researched in this paper, basing on the achievements of predecessors.1. This paper introduces the EKC's background ,basic meaning and history through providing an overview on relationship between economic growth and environmental pollution of the research status in domestic and abroad.2. This paper briefly reviewed economic growth and environmental quality status of Anhui province within ten years, economic structure of same period is also analysed .3. Mathematical models for the relationship between economic growth and pollutant emission are established in this paper, basing on statistic data of GDP per capita and industrial pollutants during 1992-2006. The simulation results shows that the parameters of industrial wastewater, COD, waste air and industrial solid waste are quadratic function, phenol and SO₂ are linear function, petroleum material is cubic function, dark matter has no regularity. All the parameters of industrial emission disappear the characteristic of Environmental Kuznets Curve (EKC) hypothesis in the study period. Since economic growth of Anhui is still in the initial stage of industrialization in which the emission of industrial pollutants has not reached the turning point. 4. Mathematical models for the relationship between different region's economic growth and main pollutant emission are established, basing on statistic data of GDP per capita and industrial pollutants during 1992-2006. The simulation results indicate that Anhui different regions's regularity of GDP per capita and main pollutants emissions have regional disparity, Regions of Anhui along the Yangtze River have strong distribution regularity of GDP per capita and main pollutants emissions, the middle region in Anhui is followed, north and south region's regularity is gradually weakened. Regularity of GDP per capita and main pollutants emissions is mianly related to different regions's economic development level. COD and SO₂ emissions of Ma'anshan appear the characteristic of Environmental Kuznets Curve (EKC) hypothesis in the study period,their tuning point are 25862 yuan and 24291 yuan; as far as the two parameters of industrial emission are concerned,the city has crossed the turning point of EKC curve.The simulation results of industrial emission parameters shows diverse regularity,which indicates that not all the parameters of industrial emission would fulfill the characteristic of EKC hypothesis.Not all the parameters of a city could show the regularity.5. Cost and effectiveness of environmental protection policies of Anhui province is analysed and some policy suggestions are also put forward ,according to the results of Anhui and its different regions's regularity of GDP per capita and main pollutants emissions.
