摘要
采用并行网络DEA模型和经典ccR模型评估了2001-2012年滇池流域水污染防治收费政策点源防治绩效。结果表明，相比并行网络DEA模型，CCR模型容易高估系统效率，结果区分度较低。由并行网络DEA模型评估结果可知，滇池流域水污染防治收费政策点源防治绩效平均值为0．695，整体效率较低，且“十一五”期间平均绩效高于其他年份；作为收费政策，适当提高政策征收标准，可促进企业和居民提高用水效率，降低污染物排放，有助于提高政裳的实施绩效；滇池流域污水处理收费政策点源防治绩效较高，而阶梯水价政策和排污收费制度实施绩效较低，未来滇池流域可通过进一步提高阶梯水价征收标准和通过排污收费制度费改税等措施以提高阶梯水价政策和排污收费制度点源防治实施绩效。
The performance of water pollution control charging policy of the Dianchi Lake basin from 2001 to 2012 was assessed by parallel network DEA model and CCR model. The results showed that compared to parallel network DEA model, the CCR model was more likely to overestimate the efficiency of the whole system, and had lower discernibility ability which could not analyze the efficiency of subsystems. The results of parallel network DEA model showed that the average efficiency value of water pollution control charging policy of the Dianchi Lake basin is low with the average value of 0.695. The average efficiency value during the ＂Eleventh Five-Year Plan＂ is higher than the other years. As the water pollution control charging policy, adjusting the imposed standards of different policies appropriately would help to reduce pollutants emissions, improve the water-use efficiency and enhance the implementation efficiency level of the policies. The efficiency value of sewage treatment charging policy is much higher than that of the water pollution levy system and water price ladder policy. Thus, the Dianchi Lake basin could raise the standards of water price charges or levy taxes in order to improve the performance levels of the water pollution levy system and the water price ladder policy.
