摘　　要：文章运用DEA模型的CRS与VRS模型对2010年中国35个主要城市的工业废水治理效率进行静态分析,并在考虑固定资产投资价格指数后,运用Malmquist TFP指数对这些城市2000~2010年工业废水治理的名义全要素生产率和实际全要素生产率进行动态分析。结果表明,2010年35个主要城市的工业废水治理平均综合效率仅为0.508,达到DEA有效的城市仅占总数的13.8%,且63.9%的城市处于规模效率递减阶段;2000~2010年这些城市工业废水治理的名义TFP和实际TFP分别为0.957、0.967。不同城市的工业废水治理效率差异过大且技术进步不足是导致整体效率偏低、效率改进缓慢的主因。This thesis applied the VRS model and CRS model (different forms of DEA model) to statically ana-lyze the efficiency of industrial wastewater control of China’s 35 key cities in 2010, and used the Malmquist index to dynamically analyze these cities’ nominal total factor productivity (TFP) and the actual total factor productivity from the year 2000 to 2010, after taking fixed-asset investment price index into consideration. The result shows that in 2010 the 35 key cities’ average efficiency of industrial wastewater control only comes to 0.508, only 13.8% among them reached the DEA effective, and 63.9% are in a condition of reducing efficiency. The nominal TFP of the crucial cities’ industrial waste water remedy is 0.957 and the actual is 0.967. The main reason of this technolo-gical change is the gap in the efficiency of industrial wastewater control between different cities and technological backwardness.
