The so-called grain risk fund refers to the special funds used by the central and local governments to stabilize the grain market price, maintain the normal circulation order of grain and implement economic regulation. It is mainly used for the interest and expenses of national grain and oil reserves and national special grain reserves, as well as the expenses needed to adjust the grain market price by using central grain reserves under special circumstances. It is used for the interest, expenses and differential expenses incurred by local governments to stabilize the grain market price, as well as subsidies for farmers in poor areas to increase their expenses due to rising grain prices. The grain risk fund saved in the current year is carried forward to the next year for rolling use.
