| 摘 要： | The process of economic activities is on the basis of tremendous material inputs. China has been discharging an enormous amount of waste, giving rise to a wide range of environmental impacts. The method of economy-wide material flow analysis （EW-MFA） is one of the effective tools to examine the flow of materials entering physical economies, and recognize early environmental problems. Relevant researches are still at the early stage in China and most focus on material throughput but are rarely concerned about the utilization of recycling resource and environmental impact. Based on more than 3,000 items of data related, materials entering Chinese economy are classified into three types, and then the characteristics of material input and environmental impact are presented for the years 1990-2005 by using the indicators derived from EW-MFA. The Ratio of Recycled Material （RRM） is added as the new indicator in order to be in accordance with the need of circular economy being promoted in China. Results show that the great changes in the structure of material input cause the continuous increase of industrial solid waste emissions and the bogging down of material productivity. The RRM reveals that the utilization of recycling resources remains at a fairly low level in China. Finally, some weakness of EW-MFA is discussed according to the calculated results.

| Abstract: | The process of economic activities is on the basis of tremendous material inputs.China has been discharging an enormous amount of waste, giving rise to a wide range of environmental impacts.The method of economy-wide material flow analysis (FW-MFA) is one of the effective tools to examine the flow of materials entering physical economies, and recognize early environmental problems.Relevant researches are still at the early stage in China and most focus on material throughput but are rarely concerned about the utilization of recycling resource and environmental impact.Based on more than 3,000 items of data related, materials entering Chinese economy,are classified into three types, and then the characteristics of material input and environmental impact are presented for the years 1990-2005 by using the indicators derived,from EW-MFA.The Ratio of Recycled Material (RRM)is added as the new indicator in order to be in accordance with the need of circular economy being promoted in China.Results show that the great changes in the structure of material input cause the continuous increase of industrial solid waste emissions and the bogging down of material productivity.The RRM reveals that the utilization of recycling resources remains at a fairly low level in China.Finally, some weakness of EW-MFA is discussed according to the calculated results. |
