基于Harris-Todaro主体的城乡人口迁移模型
A Harris-Todaro Agent-Based Model to Rural-Urban Migration
摘要：
哈里斯-托达罗模型的农村-城市迁移过程中的代理人为基础的方法下重新审视。工人的迁移被解释为一个通过模仿的社会学习过程，并通过计算模型形式化。通过模拟这个模型，我们观察到一个过渡的动态与总人口的城市部分的持续增长，朝着一个平衡。这种均衡的特征是城乡预期工资差异的稳定（广义哈里斯-托达罗均衡条件）、城市集中和城市失业。这些经典的结果最初由Harris和Todaro得到的是我们模型的涌现性质。
英文摘要：
The Harris-Todaro model of the rural-urban migration process is revisited under an agent-based approach. The migration of the workers is interpreted as a process of social learning by imitation, formalized by a computational model. By simulating this model, we observe a transitional dynamics with continuous growth of the urban fraction of overall population toward an equilibrium. Such an equilibrium is characterized by stabilization of rural-urban expected wages differential (generalized Harris-Todaro equilibrium condition), urban concentration and urban unemployment. These classic results obtained originally by Harris and Todaro are emergent properties of our model.
