本研究分析了1998 - 2009年中国工业部门大气污染物的管理情况。采用对数均值分解指数分解分析法，重点分析了燃煤污染强度（CPI）、末端治理（EOP）、能源结构（EM）、生产效率变化（EFF）和生产规模变化（PSC）等5个因素对大气污染物排放量的影响。三种污染物是本研究的主要焦点：二氧化硫（SO2），粉尘和烟尘。本文的新奇之处在于利用污染治理技术变革的规模效益效应，分行业研究淘汰政策对中国大气污染管理的影响。首先，中国工业部门的SO2排放量的增加，因为生产规模的增加进行了论证。然而，引起这种变化和能源效率提高的EOP设备阻止了与产量增加相称的SO2排放量的增加。第二，在1998年至2009年期间，除钢铁行业外，所有行业的烟尘排放都得到了成功的减少和控制，尽管这些行业的生产规模扩大了。这一减少是通过EOP技术和能源效率的改进实现的。1998年至2009年，中国工业部门的粉尘排放量减少了近65%。通过在生产过程中实施EOP技术和污染预防活动，特别是在水泥行业，成功减少了排放量。最后，水泥工业的污染防治是由于生产技术的发展，而不是规模效益。(C)2013爱思唯尔有限公司保留所有权利。
This study analyzes the management of air pollutant substance in Chinese industrial sectors from 1998 to 2009. Decomposition analysis applying the logarithmic mean divisia index is used to analyze changes in emissions of air pollutants with a focus on the following five factors: coal pollution intensity (CPI), end-of-pipe treatment (EOP), the energy mix (EM), productive efficiency change (EFF), and production scale changes (PSC). Three pollutants are the main focus of this study: sulfur dioxide (SO2), dust, and soot. The novelty of this paper is focusing on the impact of the elimination policy on air pollution management in China by type of industry using the scale merit effect for pollution abatement technology change. First, the increase in SO2 emissions from Chinese industrial sectors because of the increase in the production scale is demonstrated. However, the EOP equipment that induced this change and improvements in energy efficiency has prevented an increase in SO2 emissions that is commensurate with the increase in production. Second, soot emissions were successfully reduced and controlled in all industries except the steel industry between 1998 and 2009, even though the production scale expanded for these industries. This reduction was achieved through improvements in EOP technology and in energy efficiency. Dust emissions decreased by nearly 65% between 1998 and 2009 in the Chinese industrial sectors. This successful reduction in emissions was achieved by implementing EOP technology and pollution prevention activities during the production processes, especially in the cement industry. Finally, pollution prevention in the cement industry is shown to result from production technology development rather than scale merit. (C) 2013 Elsevier Ltd. All rights reserved.
