Study on the relationship between iron and steel industry output value and the "three wastes" emission

By using the 2001~2011 Ferrous metal smelting and rolling processing industry environment of economic data and log two environmental Kuznets model to simulate the relationship of Three kinds of “three waste” emissions and economic development. The study found the iron and steel industrial wastes emissions and iron and steel industry output value consistent with the environmental Kuznets curve. The EKC curve of steel industrial wastewater and solid waste emissions is right branch of inverted u-shape curve, has been turning point, has been in the downlink period. The EKC curve of industrial emissions in an inverted u-shape curve to the left, showing an upward trend, but increase the amplitude decreases with the increase of steel industry output value, therefore waste become a major iron and steel industry pollution source.
