The Efficiency Analysis on Material Metabolism in Liaoning Province
Abstract:
From the view of material metabolism efficiency, resource productivity in Liaoning Province has been improved strikingly as well as the material metabolism efficiency and the material excretion efficiency. From 2006, the material consumption per GDP and the reducing speed of garbage output quantity are slowing down while the material metabolism efficiency is stepping into a gradually-improving period. The environmental impact model IPAT created by Professor Ehrlich has been used for calculating the changes of environmental impact these years. The result shows that environmental impact in Liaoning Province tends to raise gradually, so the task of lowering resources and environment pressure in the future is quite urgent and it is necessary to seek for a reasonable material resource configuration.
