“第一性原理”在社会产业模型中的仿真

Simulation of the “First Principle” in Social Production Model

用"第一性原理"来看待经济社会,其实就是用物理学的方式来模拟最原始的人类社会经济活动,重新假设他们的分工、交换与协作。从经济物理学的研究视角,引出了一个简单产业经济(SP)仿真模型,在模型中用物理中的粒子关系还原了最原始的人类生产关系,赋予了个体经济社会中的特定角色和行为规范,并列举了模型仿真的几种常见的经济现象,与实践数据进行比较后发现,模型仿真结果与真实经济中的阶层分布、公司规模、收入分配差距等均有惊人的相似度。

When we use the "First Principle" to look into the economy, we are trying to understand it in a physical way, so that we assume the economy starts from primitive state, and regulate how each people(agent) related(e.g., hire, employed, pay, consume) to each other. We introduce a Social Production(SP) Model which conducts these rules, and show how it simulates some economic stylized facts, e.g., the firm dynamics, the GDP growth rate and business cycle, the income distribution, and etc.
