Income changes of National University Corporations focusing on income items

Following the incorporation of Japan's national universities, governmental block grants decreased. In response, the national universities have sought to expand their revenue streams to offset decreased governmental block grants. In that context, the purpose of this article is to clarify the income stream changes of national university corporations in Japan. The total income of all national universities, after incorporation, increased by 2.7 billion USD (2005-2011) (29.3 billion USD to 32.0 billion USD: 1USD=80.16YEN), while governmental block grants decreased by 0.8 billion USD (13.3 billion USD to 12.5 billion USD I ratio of the item against the all incomes 45%-39%). The increase in university hospital incomes is the biggest factor in the next increase (84% of the total income increase I 7.6 billion USD to 9.8 billion USD I ratio of the item against the all incomes 26% -31%). Research grants and research contracts also increased (3 .4 billion USD to 4. 7 billion USD I 11% -15% ), while tuition income decreased ( 4.2 billion USD to 4.1 billion USD I 14%-13%). Private donation income slightly increased from 0.78 billion USD to 0.83 billion USD (3% -3%). Current estimates suggest that in four years university hospital income might eclipse income from governmental block grants. In addition, it is worth noting that, unlike the United States and elsewhere, when the Japanese government decreased the block grants, tuition income decreased as well. Focusing on the individual university, there is a strong negative correlation between the size of total income and the decrease in the governmental block grant. On the other hand, there is a strong positive correlation between the size of total income and the increase in university hospital incomes, research contracts income and research grants. This means that the bigger universities, in terms of total income, the bigger the decrease in block grants they received. At the same time, they received larger increases in hospital income, research contracts income and research grants. This means that the bigger universities, in terms of total income, the bigger the decrease in block grants they received. At the same time, they received larger increases in hospital income, research contracts income and research grant income. Only the change ratio of governmental block grants is significantly correlated (negatively) with the size of total incomes. This means that once the size of each university's total income is controlled, there is no clear correlation between the size of total income and the change ratio of other income, e.g., research grants income. However, the change ratio of total incomes is still positively correlated with the size of total university incomes. Above all, the size of total income of the national universities has a strong effect on the change ratio of total incomes. This means that under this financial arrangement, large and comprehensive universities have large advantages in earning money. This may pose certain risks to long term academic diversities and harmony among the national universities
