Abstract: With the continuous development of economy and technology, copper is widely used in electric power, machinery, construction, transportation, national defense and other important fields.In the field of non-ferrous metal consumption, the consumption of copper is only less than that of aluminum.In 2020, affected by the pandemic of Covid-19, the global copper industry is hard to move forward and the market is fluctuating, global copper concentrate output decreased slightly, at the same time, the supply and demand of refined copper were obviously tight, copper price increased significantly.This paper systematically analyzes the factors affecting copper supply and demand,by using the sector forecasting method, focus on the future copper demand of global wind power infrastructure and new energy vehicle industry.During the 14^th five year plan, the cumulative new copper demand of global wind power facilities and new energy vehicle industry is 2 408 thousand tons and 3 617 thousand tons respectively, and the copper demand of other traditional and emerging consumer areas will also increase slightly.In 2025, global copper demand will reach to 25.17 million tons, which China's copper demand will reach to 14.56 million tons, China is the main driving force of copper demand growth.
