System of exchange
利用网络分析、经济学和文化社会学概念，构建了一个交换体系分类方案，说明自由市场只是经济类型之一，其他类型并非市场缺陷，有助于分析不同交换安排并发展市场组织理论。
We develop a classification scheme of systems of exchange using concepts from network analysis, economics, and cultural sociology. This classification illustrates that the free market is but one possible type of economy and that other types are not best understood as imperfections. This classification helps to distinguish analytically among qualitatively different types of exchange arrangements and suggests bases from which to develop theories about the organization of markets and exchange systems of various types.
