《中华人民共和国价格法》第二十三条规定:“制定关系群众切身利益的公用事业价格、公益性服务价格、自然垄断经营的商品价格等政府指导价、政府定价,应当建立听证会制度,由政府价格主管部门主持,征求消费者、经营者和有关方面的意见,论证其必要性、可行性”。以往,凡涉及铁路、公路、民航、水运、邮政及电信等公用设施及公共产品的价格,一般都是“暗箱”操作。因此,“擅自定价”、“非法定价”等问题长期得不到解决,市场运作很不规范,政府、商家、消费者之间也存在着较为严重的角色冲突。本来,对这些“关系群众切身利益的事 Article 23 of the “Price Law of the People’s Republic of China” stipulates that: “To formulate a government guidance price that relates to the immediate interests of the masses, such as public service prices, public service prices, and commodity prices run by natural monopolies, and government pricing, a hearing system should be established, Presided over by the government department in charge of price and solicited the opinions of consumers, operators and relevant parties to demonstrate its necessity and feasibility. ” In the past, prices involving public facilities and public goods such as railways, highways, civil aviation, water transport, postal services and telecommunications were generally “obscure” operations.
