1. Its price is determined by the inherent characteristics and uses of its raw materials. On the one hand, it is affected by the world and domestic supply and demand, on the other hand, it is affected by the speed of domestic economic development and economic policies. In the past few years, due to the global economic depression and the Southeast Asian financial crisis, the lack of domestic economic demand led to the decline of aluminum price. Later, through the national micro regulation and control, the implementation of active fiscal policy, the expansion of domestic demand, and led to the increase of aluminum consumption.2. As the capacity of domestic antirust aluminum plate raw materials is added too fast, on the one hand, the domestic alumina supply is tight; on the other hand, the micro economic environment determines that the demand for aluminum can not be added too fast in recent years, which will be more conducive to promoting the export of domestic antirust aluminum plate raw materials to a certain extent. However, the large energy consumption and high cost of domestic anti rust aluminum plate raw materials restrict the development of anti rust aluminum plate raw material industry in China. Therefore, it is still necessary to import a certain amount of aluminum every year to meet the domestic demand. The adjustment of import and export tariff and the change of exchange rate will affect the domestic aluminum price.
