Evaluation of Economic Development and Industrial Pollution in Chongqing in Recent Years Based on EKC

In recent years Chongqing has made rapid economic development. But it also faces an enormous pressure in energy-saving and carbon emission reduction especially in the industrial fields. This paper constructs the models of Environmental Kuznets Curve (EKC) with time series data of Chongqing from 1995 to 2006. The basic data include the industrial waste discharge per unit GDP, industrial waste discharge per capita GDP and corresponding environmental data. The relationship between typical environmental indexes and increase of GDP is analyzed. The results show that the industrial waste discharge per unit GDP displays general downward trend, which indicates the technological progress and readjustment of industrial structure have yielded significant environmental benefit. Meanwhile, on the whole the relationship of economic development and environmental pollution in recent years donot conform with the obvious characteristics of EKC. The fitting EKC curves of all environmental indexes have no turning point. So the efficient environmental policy and huge environmental investment of Chongqing have to make the economic and environment develop sustainable and healthily.
