Outline of Final Research Achievements

I studied issues of regional banks in Japan and the optimization of bank management from the perspective of declining loan-deposit ratio. The mainly factors contributing to the problem are still the old business policy of acquiring deposits, and the fact that the theoretical interpretation of money issuance or creation has not been correctly determined by the banks.
In this study, the variation of the loan-deposit ratio in Japan is contrasted with that in Scandinavian countries, and it is shown that the relationship between fiscal expenditure or spending and banking function on a macro basis is a significant factor. Japanese banks are heavily involved in JGB , and it is clear that the decline in the loan-deposit ratio is caused by cooperation with the budget deficit rather than by the decline in the local economy.

Academic Significance and Societal Importance of the Research Achievements

地方銀行の経営環境の悪化に対応するための理論分析を行った研究である。銀行システムがおかれている環境，特にマクロ環境の変化の要因分析に注力した。
具体的には預貸率低下のマクロ環境の対比を，スカンジナビア諸国との国際比較により，日本の環境悪化の要因が，政府債務の増大に伴う銀行システムによる政府債務の消化ないし引き受けに要因が認められることを明らかにした。
これは社会の高齢化や地方産業の衰退に要因を求める一般論とは異なり，貨幣供給能力を有する地方銀行を含む銀行システムが政府債務を引き受けることで預貸率が事後的に低下する現象のメカニズムを明らかにした。
