- W2361192263 abstract "Three methods i.e., average production function (APF), frontier production function (FPF) and data envelopment analysis (DEA) model, are employed to quantitatively assess the efficiency of China抯 urban wastewater treatment plants (WWTPs) and to identify the critical factors affecting the efficiency. Based on the data from 81 surveyed WTTPs, the three models are solved and some variables are gained. The examined variables cover the production elasticity of input factors, technological efficiency, return rate to scale, and so on. The study finds that capital is the factor with the highest production elasticity (0.507), which is followed by electricity with the production elasticity of 0.415, and labor is the factor with lowest production elasticity. The average rate to return derived from the APF model is 1.11, which shows that there is high potential to increase the profit by augmenting the inputs. Based on the results from DEA model, the relative efficiency of each sample WTTP is gained and a full WTTP list can be ordered by efficiency, which would be helpful to establish the benchmark standard for efficiency regulation." @default.
