The main body of education cost is human cost. Labor cost, also known as human resource cost, includes the introduction cost, development cost and use, management and maintenance cost of human resources. Schultz, an American economist, believes that the human resource cost in general includes the expenditure on education, medical care and domestic migration for obtaining good employment opportunities, as well as the sum of the income given up by educated adults and trained workers and other inputs to improve human quality.
Educational institutions and their levels manage and maintain human resources insurance, wages, welfare, use and motor-intensive industries. Labor costs account for the vast majority of costs. Compared with capital-intensive industries, the productivity growth of labor-intensive industries is generally slow and limited. Take the automobile industry as an example. From the past annual output of thousands of cars to the present, the production efficiency has increased by dozens or even hundreds of times. But the productivity of labor-intensive industries cannot be improved like that of automobiles. Although the class teaching system has improved the production efficiency of education, its scope is limited. Moreover, judging from the current trend of education reform in the world, it seems to be a reform trend to improve the teaching quality, reduce the ratio of students to teachers and reduce the class size. Therefore, the labor cost of education is rising.
