摘要
近年来,随着城市化进程的加快,国家对城市污水处理项目的投入也大幅度增加,污水处理厂的规模是否适应当地经济、人口、环境的发展,决定了污水处理厂的综合效益高低。本文用回归分析对西部地区山地城市10家中小规模污水处理厂2008年—2011年的运营状况进行规模经济验证分析,最后得出其存在规模经济效应,说明西部地区山地城市现有污水处理厂的规模是适合当地经济状况的,对其他地区污水处理厂规模的设计具有一定的参考意义。
In recent years, with the accelerated process of urbanization, the government has increased a large investments in urban sewage plants , and the overall efficiency of a sewage plant depends on whether the size of the sewage plant adjust to the development of the local economy, population and environment. This article is trying to make use of the theory of regression analysis to probe the small/mid scale sewage plants in Southwest of China between 2008 and 2011. Finally we＇ve found that scale economy effect do exist in the small/mid scale sewage plants of Southwest area. It shows that the scale of the sewage plants in Southwest of China is appropriate for the local economy. Also, it＇s significant to design the scale of a sewage plant in other places.
