Since copper is the most widely used nonferrous metal in China, the research on the use and recycling of copper plays a strategic role in the sustainable development of economy. In this paper the copper flow was interpreted in the SFA model of "STAF" by the four stages such as production, manufacture & fabrication, use and waste management. The change in stock and substance flow of copper in China in 2004 was analyzed, and the result showed that from 1998 to 2004, the average of PZ, PS, MZ and MSwere 49.08%, 25.98%, 57.14% and 21.45%, respectively, being far below the level of European countries. It's revealed by the comparison of copper flows in China between 1994 and 2004, the copper inflows and outflows of every stage in China had all inreased, while the recycling rate of waste copper had a lower increase than the quickly growing demand of copper. Therefore, faced with the resource crisis, the key points of the sustainable development of copper industry in China are the intensification of policy guidance and technical research, and the increase of the resource production of primary resource and the recycling rate of secondary resource.
