Brief introduction of labor market segmentation theory

The theory of labor market segmentation, also known as dual labor market model, was put forward by American economists Dolingher and Piol in 1960s. Labor market segmentation refers to the departmental differences in the labor market caused by social and institutional factors; The differences in access to labor market information and channels among different groups of people lead to obvious differences in employment departments, positions and income patterns, such as the stratification between race, gender and immigrants.
