摘要

In this paper we use comparative method to analyze the evolution law and development trend of aluminum resources supply and demand in China and the United States, the purpose is to predict the future China aluminum supply and demand trend. This paper analyses the primary aluminum production, secondary aluminum production, import and export volume, consumption of aluminum and other data in China from 1956 to 2013, and in the United States from 1900 to 2013. The results show that: (1) the aluminum resources supply and demand trend of the United States are in line with "S" shape, while the primary aluminum development show a trend of inverted "U" curve; (2) China primary aluminum production and consumption trend both appears inverted "U" curve; (3) China begin to reduce the external dependency of secondary aluminum with its self-sufficiency ability raise; (4) China secondary aluminum production ratio will be more than primary aluminum ratio.
