经济网络的自组织动力学——基于个体之间经济交易的研究

摘要

Based on dynamical transaction model,transactions among agents are used as a tool to study the formation, development dynamics of economic networks in a complex system. It is found that,agents'optimal optional transaction is useful to improve self-organization evolution of the industy, and complex economic system's natural order comes from the complex stable economic network resulted by agents' transactions. The limitness of individual's rational expectation can result in opportunistic behaviour,then cause economic network′s self-organized criticality and periodical fluctuation on the macro-level even economic crisis.%在交易动态模型研究的基础上,以个体之间的交易为工具,主要对复杂系统中经济网络形成、发展的动力学进行研究论述.研究发现:个体的优化选择交易有助于推动产业结构的自组织进化,经济复杂系统的自然秩序来源于经济个体通过交易关系联结起来的、稳定的复杂经济网络;但由于个体理性预期的局限性,有限理性的微观个体在价格信号指引下容易陷入逐利投机状态,推动经济网络的自组织临界性形成,从而导致宏观经济的周期波动,乃至于经济危机的形成.
