The Analysis of Factors Affecting SO2 Emission of Chinese Industry

This paper integrates Grossman decomposition model with Logarithmic Mean Divisia Index (LMDI) Decomposition method to construct a new decomposition model concerning industrial pollution factors. We decompose the influencing factors with the constructed model which selects year 2005 to 2008 as analysis period and Chinese industries and SO₂ emission of its internal industries as research object. For Chinese industry and its domains, the dominant influencing factor of SO₂ emission is scale effect in analysis period. The variation of scale goes against the reduction of SO₂, whereas structural variation benefits that. Improve the clean technology effect or pollution treatment effect is two effective ways of reducing SO₂ emission. Only by lowering down the emission of SO₂ of leading domains, the reduction effect can be more obvious.
