The purpose of this study is to find ways to improve the total cost of education and the cost-sharing structure of each major based on the empirical analysis of the education cost, annual average tuition, and employment rate of each department. To achieve the purpose, it analyzed 84 departments of undergraduate courses at AB University, a large national university, due to the limitation of data collection for educational cost analysis. Based on the results of the study, the following suggestions were made for the improvement of the total education cost and cost-sharing structure of major colleges and universities. First, the total cost of education at AB National University is 46% to 73% of Australian universities, and the total cost of education in agriculture, natural science and engineering is very low at 50% in Australia. In order to enhance the competitiveness of national universities, it is necessary to raise the total education cost by majors of all fields. Second, in order to increase the total education cost by major, it needs to improve the overall government burden, except for the areas of management, administration, and law. Third, considering that engineering, veterinary medicine, total education cost, cash expenditure cost, and employment rate per student are relatively higher than other majors, the tuition level is improved rather than the current level. However, at the same time, to improve the quality of education, it is necessary to increase public support more dramatically than now.
