项目摘要

Economic systems are made of a large number of interacting agents and display also surprising self organizing features and macroscopic order in spite of the underlying disorder among its constituents. It is easy to understand why there is a great temptation to extrapolate that line of thought to account for some basic, stylized facts of economic systems. This approach however amounts to take especially into account the interactions among the agents, and the way in which they coadapt to each other and to regard equilibrium in a more dynamical way.In this research we construct a virtual market (VM) in computer, and the macro dynamisms of the market are analyzed from the micro point of view. The VM is constructed based on the model of 'Economics of Complex Systems'. Economics of Complex Systems has several features : increasing returns to scale, bounded rationality, self-organization, one-to-one trading, and so on.In this model, the market consists of three types of heterogeneous agents, named Supply agent, Demand agent, and Intermediate agent. Partnering between supply and demand agent is decided by '4-Heap algorithm'. In this market, supply agents produce one kind of goods, and demand agents consume all kinds of goods. Multiple intermediate agents are existing in this market, and then multiple local 'markets' are formed.At First, we introduced the idea of economics of complex systems, and the basic market model, which abstracts and simplifies an actual market, was defined and constructed. Then several simulation experiments have been executed to analyse basic characteristics of the VM. Some distinctive characteristics of the price dynamisms have been described in that simulation, and the decision mechanism on the market price has been analysed by the behaviour of each agent. Finally the applicability of the proposed framework into resource allocation problem for supply chain management has been also discussed.

经济系统是由大量相互作用的主体组成的，尽管其组成部分之间存在潜在的混乱，但它也表现出令人惊讶的自组织特征和宏观秩序。很容易理解，为什么会有很大的诱惑去推断这一思路，以解释经济体系的一些基本的、程式化的事实。然而，这种方法的数额，特别是考虑到代理之间的相互作用，以及他们相互适应的方式，并考虑均衡在一个更动态的方式。在本研究中，我们构建了一个虚拟市场（VM）在计算机上，和市场的宏观动态分析从微观的角度来看。VM是基于“复杂系统经济学”模型构建的。复杂系统经济学具有规模报酬递增、有限理性、自组织、一对一交易等特征，在该模型中，市场由三种类型的异质主体构成，即供给主体、需求主体和中介主体。供需主体之间的合作关系由“4堆算法”决定。在这个市场中，供给主体生产一种商品，需求主体消费各种商品。本文首先引入了复杂系统经济学的思想，定义并构建了对实际市场进行抽象和简化的基本市场模型。通过仿真实验分析了虚拟机的基本特性。在该模拟中描述了价格动态的一些独特特征，并通过每个代理人的行为分析了市场价格的决策机制。最后讨论了该框架在供应链管理资源分配问题中的适用性。
