从传统的观点看,交换作为一种简单可观的人类行为,是不符合复杂性特征要求的,但对其进行复杂性分析后可以发现,交换在本质上是一种信息综合决策行为系统,符合组分复杂、结构复杂和功能复杂三方面的复杂性要求,是一种复杂系统。在认识了交换复杂性的本质后,对交换复杂性的基本模型进行了理论描述,并指出了将复杂性理论引入交换问题的研究所内含的方法论意义。 From a traditional point of view, exchange as a simple and observable human behavior does not meet the requirements of complexity characteristics, but after its complexity analysis, we can find that exchange is essentially a system of information comprehensive decision-making behavior, in line with Complex components, complex structure and complex functions of three complex requirements, is a complex system. After understanding the nature of exchange complexity, this paper describes the basic model of exchange complexity and points out the significance of the methodology embedded in the institute that introduces complexity theory into exchange problems.
