摘要
价格形成机制是微观经济学的重要组成部分。西方经济学认为"在其它条件不变的情况下,供需决定价格的产生,而价格又反作用于供需"。这一理论是有前提假设的,即完全竞争、完全信息和完全理性。但是,至于价格信息是如何传递给生产者和消费者的,是通过什么样的渠道和中介系统传递的,传统经济学没有进行详细讨论。从这个意义上讲,传统经济学只是把价格形成看做了一个"黑箱"。昝廷全(2007)从哲理的角度分析了传统经济学中价格机制存在的缺陷,并深入分析了其与价格信息传递的关系。本文通过引入2002年AminMousavi等学者根据Z.Pawlak的粗糙集理论提出的信息粗交流理论,特别是在刘纪芹、史开泉研究成果的基础上,建立了关于"信息粗交流在价格形成中的作用"的单向路径信息粗传递模型,提出了如何使价格信息源尽量保真的方法。最后,给出了一个具体应用实例。
Price formation mechanism is an important part of the microcosmic economics.In western economics,In case of fixed other conditions,demand and supply decide the price,and the price reacts demand and supply.This theory is on the assumption of complete competition,complete information and complete rationality.But,how is the price information transmited to producer and consumer？ And what is the channel and media system does the price information transfer by？ These are not discussed detailly in orthodox economics.In this sense,orthodox ecnomics regards price formation as a ＂black box＂.Zan Tingquan（2007） analysed the imperfection of price mechanism in orthodox economics.He also deeply analysed the relation between price mechanism and transmission of price information.By introducting Rough Communication brought forward by AminMousavi etc,this article,in particular,on the basis of the research work by LI Ji-qin and SHI Kai-quan,establishes a model of one-direction rough communication.And it puts forward the method to remain price information source.An applicative intance is given in the end.
