An Analysis of the Three Turning Points in the "S-shape" Rule of Copper and Aluminum Demand
铜、铝需求“S”形规律的三个转变点剖析

This paper analyzes three key transition points for the copper and aluminum per capita consumption S-shape track. It figures out theoretically the time when those three transition points appear for aluminum and also points out that that it shares the same period with aluminum for copper per capita consumption to show the transition points, aluminum comes slightly earlier than copper. Base on this provision, the paper analyzes the copper and aluminum demand tendency in the future for our country and concluded that the demand for copper and aluminum demand will be on the summit around 2020, which will be double by then.
