Abstract
In this research, the data envelopment analysis (DEA) model of measuring the eco-efficiency of urban material metabolism has been constructed based on the urban material input and output indicators. According to the data of Xiamen from 1985 to 2007, an empirical study was conducted to measure the eco-efficiency of urban material metabolism using DEA program. The results showed a general downtrend of Xiamen's eco-efficiency of material metabolism from 1985 to 2007, in which there were 15 efficient years and eight inefficient years. The eco-efficiency and urbanization rate of Xiamen was remarkably negatively correlated. Moreover, the results revealed at 4 years (1995, 2001, 2002 and 2003) there had been undesirable output slack (environmental pollution), and at 2 years (1991 and 1999) there had been desirable output slack (GDP), and at 8 years there had been input slack (water, land, food and energy), especially for water and energy. Finally, some suggestions on promoting the eco-efficiency of urban material metabolism were put forward.
