RURAL–URBAN MIGRATION IN ECONOMIC DEVELOPMENT
综述了当代发展中国家城乡迁移的理论文献，涵盖刘易斯模型、托达罗模型及后续研究，并探讨了求职、家庭决策和非正规部门的作用。
Abstract. This paper provides a review of the theoretical literature on rural–urban migration in contemporary LDCs. The paper begins with a brief discussion of the Lewis model before going on to discuss the Todaro and the Harris–Todaro models and the large literature which these models have spawned. The question of job search in the context of migration and the role of family members in migration decisions are considered next. The paper then takes a closer look at the Informal sector and also sets out alternative migration functions to the ones usually employed in the literature. The paper concludes with a brief note on some of the important implications arising from our study.
