Base on the framework of material flow analysis (MFA) proposed by Eurostat, this paper collected relateddata and conducted a regional MFA for the Chengyang District in Qingdao. The indicators such as Direct Material Input(DMI), Direct Material Consumption (DMC) and Exports are calculated or estimated for the period of year 1995through 2004. Several derivable indicators defining direct material productivity and material intensity are also evaluatedand some valuable conclusions were drawn. DMI in absolute number increased from about 1645.9 kilotons in 1995 toabout 8052.5 kilotons in 2004. Imports contribute to about 47 to 69% of DMI, and the biggest component of imports isfossil fuel that approximately accounts for 50% of imports. DMI per capita of Chengyang District increased rapidly andreached 17.4 tons in 2004. Compared with other five economies studied by WRI, material consumption intensity ofChengyang District is significantly lower than developed countries, which indicates that Chengyang District is still in adevelopment stage. The direct material productivity (actual GDP per DMI) increased 59.1% from 1995 to 2004 and hasbeen higher than either of studies in China, which indicates efficiency of resources utilization has improved obviously inChengyang District. But there was significant increase in material input in the last decade, which shows that rapidincrease of economy is highly dependent on requirement and consumption of natural resources. Therefore, in order topromote the sustainability, it is essential to develop circular economy and improve utilization efficiency of resources.
