本文计算了1996-2003年中国30个地区工业固体、水、气三大废物的有效分解率。采用单产出（真实的GDP）和五投入（劳动力、真实的资本存量、固体废物、废水和废气）的数据包络分析（DEA）方法，计算各地区各年度的目标废物量。然后通过比较污染物的实际废弃量和实际废弃量，得到各地区每年的有效减排率。我们的主要发现是：1.东部地区是研究期间各年三废排放效率最高的地区。2.东、中、西部地区1996-2003年固体废物平均目标削减率分别为24.90%、64.77%和62.33%，废水平均目标削减率分别为14.27%、27.45%和32.01%，废气平均目标削减率分别为18.42%、43.21%和46.66%。3.由于中西部地区在三废问题上有着相似的严重性，因此，实际上，中国在三废问题上被分为两部分。4.与废水和废气的情况相比，固体废物的减少是中国最紧迫的任务。
This paper computes efficient three industrial waste abatements (solid, water and gas) for 30 regions in China from 1996–2003. Data envelopment analysis (DEA) with a single output (real GDP) and five inputs (labour, real capital stock, solid wastes, waste water and waste gas) is used to compute the target wastes of each region for each year. The efficient abatement ratios of each region in each year are then obtained by comparing the actual waste to the actual waste of a pollutant. Our major findings are: 1. The east area contains the most efficient regions with respect to the three wastes in every year during the research period. 2. The east, central and west areas have 1996–2003 average target abatement ratios of solid wastes of 24.90%, 64.77% and 62.33%, of waste water 14.27%, 27.45% and 32.01%, and of waste gas 18.42%, 43.21% and 46.66%, respectively. 3. Because the central and west areas have similar critical problems on the three wastes, China is actually divided into two parts considering the three wastes. 4. Compared with the cases of waste water and gas, solid waste reduction is China's most urgent task.
