1. Macroeconomics \ r \ Food is the most important thing for people. As a necessary life guarantee, agricultural products have always had rigid demand. However, with the rapid economic development, the demand for agricultural products is not only manifested in eating, but also the proportion of feed use, alcohol, starch and other industrial deep processing is gradually increasing. \r\n2。 Changes in the relationship between supply and demand \ r \ nAs the basis of economics, the relationship between supply and demand is the basis for determining product prices. Therefore, when analyzing the price trend of industrial products and agricultural products, it is necessary to analyze the relationship between supply and demand. This also largely determines the future development direction of product prices. \r\n3. Seasonal factors \ r \ With the large-scale and centralized development of agricultural planting, weather conditions have an increasing impact on agricultural output, which is beyond the control of the current scientific and technological level of human beings. Therefore, the occurrence of extreme weather will inevitably affect the price fluctuation of agricultural products in the futures market.
