运用MAS技术构建了经济政策作用模型。模型中包括居民、银行、市场、行业、政府等五类智能体，并充分利用了智能体的协作、交互功能。研究中将货币政策设计为从微观个体的知识获取、决策以及宏观总量控制两个方面作用于经济运行。模拟演算结果验证了模型的有效性和实用性，得出了在一定的产业规模条件下，利率机制对货币供应及总产出作用明显，表明该模型可为政策制定者提供参考。

An economic policy simulation model is developed by using the MAS (MultiAgent System) technique. The model is composed of five categories of agents i.e. the resident agent, the bank agent, the government agent, the market agent and the industry agent, and their features are fully utilized for the agents’ cooperation and communication. The effect of monetary policy is designed as micro individual knowledge acquirement, decision making and macro overall volume control. The results obtained demonstrate the validity and applicability of the proposed model, and demonstrate that the  interest rate mechanism has a significant effect on money supply and total output under a certain industrial scale. The simulation experiment also indicates that the model is able to provide a reference to the decisionmaker.
