Market supply and demand: the price of agricultural products is affected by market supply and demand. When the market is in short supply, the price will rise. For example, in spring, people have a great demand for vegetables and fruits, but the supply is relatively small, which leads to the price increase. On the contrary, if the supply exceeds the demand, the price will fall. For example, in autumn, when the grain harvest season comes, the market supply is sufficient, and the price will fall.

Production factors: production cost is one of the important factors affecting the price of agricultural products. Production costs include input costs such as seeds, fertilizers, pesticides and labor, as well as the costs of production factors such as land and water resources. These cost changes will directly affect the prices of agricultural products. For example, if the price of agricultural production factors rises, the production cost of agricultural products will increase, and the price will also rise accordingly.
