Abstract: With a large number of empirical studies, the concept or attitude of family education has a direct impact on the education investment on their children. The rural residents who treat education as investion have become the majority. Farmers have the similar expectation on the successful education of boys and girls. The higher education the parents received, the higher the growth of investment in education. The sustained decline in the Engel’s coefficient was mainly due that the growth of education is for the cost of family life through the research on farmers investment in their children’s education and family income and expenditure.
