| Abstract: | This paper identified that there were two aspects of the effects on industrial pollution production by technological progress: the scale effect which promotes economic scale and the intensity effect which reduces pollution generation intensity.Based on the Malmquist index,a theoretical model was built to analyze the two effects,and an empirical study on the industrial SO2 production changes during 2006 and 2009 due to the technical progress was carried out.The results indicate that technical progress reduced the amount of industrial SO2 production.Technical progress reduced the amount of industrial SO2production in 2006–2007 and 2008–2009,while it was the opposite situation in 2007–2008.The scale effect was more significant in the eastern region,while the intensity effect was more significant in the central region. |
