Empirical Study on the Relationship between Economic Growth and Environmental Pollution Level in Jilin Province

Based on the Environmental Kuznets Curve hypothesis (EKC), the measurement models of various environmental pollution indicators with economic growth indicators were obtained by using the regression simulation of PASW Statistics 18.0 statistical software based on the data of environmental indicators and economic growth indicators in Jilin Province, and analyzed the characteristics of EKC. The result indicated that the EKC of environmental indicators did not completely accord with the “U” shape. The EKC of industrial wastewater discharge amount showed the “U + inverted U” shape, the inflection point appeared in 2009; The EKC of industrial waste gas emissions was in continuous growth without an inflection point; The EKC of industrial solid waste output showed the left half part of the “U” shape, the inflection point will appear in 2014. The EKC of industrial dust emissions was a shape of logarithmic function, being in a gradually decreasing trend without an inflection point; The EKC of industrial SO2 emissions showed the “U + inverted U” shape, the inflection point appeared in 2008; The EKC of COD discharge amount of industrial wastewater showed the unobvious “U + inverted U” shape, the inflection point appeared in 2009. The overall environmental pollution level in Jilin Province was in the stage of continuous improvement.
