中文摘要：

多主体模型是一种研究生态和社会、经济等复杂系统的动态研究方法，社会经济系统作为由类型多样与数量巨大的经济个体组成的复杂系统，系统中各主体复杂的相互作用表现出单个个体所不具备的特征。基于多Agent人工社会建模，在遗产继承和子辈发展方面对原始Sugarscape模型做了改进，借助REPAST软件平台，仿真研究固定资源下对不同数量人口的支撑作用，获取社会财富、个体生活水平以及社会福利随人口变化的数据，根据其变化曲线，得到经济学启示。

英文摘要：

Multi - agent model is a kind of dynamic research method on complex system of ecology,society and economy. The social economy system is a kind of complex system composed with diverse types and large numbers of economical individuals, the complicate mutual action among agents displays some characteristic that single agent does not have. Based on multi - agent artificial social modeling, improved primitive Sugarscape model in legacy succession and offspring＇ s development,draw support from REPAST software platform, research the support function on different quantity population under the fixed resources,obtain data of the wealth of society, individual living standard and the social welfare vary with population,obtain the enlightenment of economics from its curve.
