Informal employment is an important way to solve the problem of rural labor' employment.Based on the rural data of China Health and Nutrition Survey(CHNS) in 2009,the paper analyzes the Intergenerational Transmission during the process of choosing the informal employment for two generations in rural family using the recursive bivariate probability model.The study shows that factors affecting the behaviors of choosing the informal employment between two generations are different,but there is also strong intergenerational transmission or inheritance relationship.The children's behaviors of choosing the informal employment are influenced by the parental behaviors.This means the children are short of independence when choosing the informal employment in rural family.
