Material Input Analysis of Shanghai Economic and Environmental System

The objection of the study is to estimate resource and environmental costs of the economic development,evaluate the sustainability of the economicenvironmental system and help the decision-maker make better plan for circular economy.The material flow theory and methodology based on the Eurostat guidelines have been applied to analyze quantitative characteristics of the total material requirement(TMR),the direct material input(DMI) and the resource productivity(RP) in Shanghai during 1990-2003.The conclusions are shown as follows:①The enormous total material requirement and direct material input cause huge pressure on the environment on the city of Shanghai.②The resource productivity in Shanghai is 1.22 times as much as that of China in 1996 and one thirtieths of that of Japan in 2000,which shows that the efficiency of the resource utilization in Shanghai is still low.③ Technique level and institution capability have the key effects on total material requirement or environmental quality.Before 2020,Shanghai should focus on reducing the material input,developing technology and putting forward the institution capability for circular economy.
