交易成本与分工:一个分析框架

通过设计一个简单的模型,可以分析交易成本与分工水平的关系,即只要交易成本足够低,而且交易双方存在比较优势,他们就总能从分工中获利;如果交易双方不存在内生和外生比较优势,那么,除了生产活动专业化报酬恒定外,不论是专业化经济还是专业化不经济,交易双方都可以从分工中获利。交易双方从分工中获得利益的大小,取决于交易成本的大小,因此,分工水平的发达程度取决于交易成本的大小。

Transaction Costs and Division of Labor: An Analytical Framework

In this article,the author designs a simple model to analyze the relationship of labor division and transaction costs.By such an analytical framework,the author makes a conclusion: if the transaction costs are low enough,then if there exists comparative advantage,both sides of transaction can benefit from labor division,if there doesn't exist exogenous and endogenous comparative advantage,both sides of transaction can still benefit from labor division except that there is constant return to specialization.
