In market economy, man is both the essential productive factor and the consuming subject. Education promotes the two aspects. As shown by investigations on the influence of educational attainment on consumption, education has great influences on people’s consumption level, consumption structure, consumption modes and consumption concepts. The world is entering the stage when people are paying more attention to environmental protection, ecological balance, and the building of harmonious society. Therefore, economics of education should not only focus on the exploitation and cultivation of human capital in the instrumental aspect of man, and for the sake of his all-round development, it should also center on the enhancement of consumption level, consumption concepts, rational consumption and consumption skills.
