7.5 Conclusions
Data observation and cross-section analysis reached the following statistical conclusions. First, the information system development cost, had a positive correlation with the loan and bills discounted in each bank, and the total assets. Second, internal system development personnel and the system operation personnel were not always accorded the privileges of other sector personnel. Therefore, there were few possibilities for these personnel to move between banks through the labor market. Finally, banks with independent strategy, which do not take the guidelines from the Bank of Japan and governments into account, invest in information systems more positively accompanied with the increase of the loan arid bills discounted and the total assets than banks of the dependent type.
