信用、抵押与企业

当代财经 2005年第8期 13-18页

作者：邢振东四川大学经济学院四川成都610064

科斯以来,企业理论总体上都沿用了市场与企业的两分法。这些理论虽然对揭示企业的真相有一定贡献,但其从一开始就忽略了一个基本的问题:既然企业性质与市场交易密不可分,那么市场交易的性质及其发生的前提条件是什么呢?经过分析与考证发... 详细信息

科斯以来,企业理论总体上都沿用了市场与企业的两分法。这些理论虽然对揭示企业的真相有一定贡献,但其从一开始就忽略了一个基本的问题:既然企业性质与市场交易密不可分,那么市场交易的性质及其发生的前提条件是什么呢?经过分析与考证发现,交易发生的前提条件是信用。信用不是“物”而是一种契约关系,建立在客观经济抵押的基础上。对企业而言,信用内含的经济抵押不但粘住了资产所有者赋予企业以生命,而且决定了企业的形态与规模。

如何防范机会主义行为是企业理论研究的重点之一。经过对相关理论的回顾与评述,发现现有防范机会主义的文献中,往往忽视了一个重要的因素———客观的物质基础。那么这个基础是什么?经过研究,发现是信用。理论经济学研究的信用只是注重了信用“工具”的一面,却忽视了信用背后的经济关系。信用的实质是一种契约,是建立在一定抵押基础之上的契约。信用是企业内的基本关系,决定了企业内的收益安排。

企业信用:一个新的分析视角

四川大学学报（哲学社会科学版） 2005年第1期 27-32页

作者：朱方明邢振东四川大学经济学院四川成都610064

在经济学中,信用一般被认为是一种特殊的价值运动形式,即商品赊销或货币借贷关系。这种狭义的理解将信用物化,并使其游离于企业基本问题之外。我们理解的信用是一种广义的信用关系,是企业利益相关者之间基于经济利益的相互信任与授信机... 详细信息

在经济学中,信用一般被认为是一种特殊的价值运动形式,即商品赊销或货币借贷关系。这种狭义的理解将信用物化,并使其游离于企业基本问题之外。我们理解的信用是一种广义的信用关系,是企业利益相关者之间基于经济利益的相互信任与授信机制。从企业产生的前提条件、企业参与者的行为逻辑及企业的基本关系等方面看,信用是企业生存和发展的重要基础,企业制度的变迁史实际也是企业信用的发展史。
