Price adjustment fund, the so-called price adjustment fund, is a special fund used by the government to regulate market prices, balance supply and demand or support operators. 1988 the State Council clearly put forward the requirement of establishing non-staple food price adjustment funds in cities across the country in the "Notice on Trial Implementation of Appropriate Subsidies for Employees from Retail Price Changes of Major Non-staple Foods". Article 27 of the Price Law stipulates: "The government can establish an important commodity reserve system, set up a price adjustment fund, regulate prices and stabilize the market."
