农户交易中介化——概念界定与经济合理性论证

Intermediary Transaction in the Process of Household Transaction

目前我国绝大多数农户采用直接化的交易方式,近年来,出现了一种新的交易方式,即"交易中介化",到底是哪种交易方式更有效?哪种方式更能节省交易成本?所以必须对其内涵进行界定,以"交易成本"为分析工具,借助一个关于基础交易成本与交易方式选择的模型。由于农户的有限理性、不确定性、交易频率、资产的专用性等因素影响,农户的基础交易成本是相当高的。从微观经济学的角度来看,直接化的交易还会使农户的福利受到损失。换言之,中介化交易是一项有效的制度安排。

At present, most households adopt direct transaction pattern in China, which breeds a new way of transaction, i. e. ＂intermediary transaction pattern＂ . But which is more efficient and less costful？ By defining it, the paper presents a model about transaction cost and pattern, for the reasons of limited rationality, uncertainty, transaction fluency and asset specificity. It draws a conclusion that the transaction cost is high in direct transaction pattern. As an transaction pattern, with economical rationality in terms of microeconomics intermediary transaction proves more efficient.
