对政府定价实行听证会制度，有利于政府价格主管部门制定价格的科学化和规范化。以往的实践表明，由政府直接制定某些商品和服务的价格往往存在一定程度的“失灵”：———价格缺乏灵活性。价格一经制定容易固定不变，不能及时反映成本或供求情况的变化，使价格难于很好地发挥 The implementation of the hearing system for government pricing is conducive to the government’s price authority in formulating prices that are scientific and standardized. Past practice has shown that there is often a certain degree of “failure” in the price of certain goods and services that are directly formulated by the government: — The price lacks flexibility. Once prices are fixed, they are easily fixed and cannot reflect changes in costs or supply and demand in time, making prices hard to play well.
