Abstract

本稿では、日本の家計貯蓄率の過去と将来について検証し、日本の家計貯蓄率は過去に おいて常に高かった訳ではなく、戦後に限れば、15%の水準を上回ったのは、1961~86 年の26 年間の間だけであったということを示す。なお、日本の家計貯蓄率は1970 年代 半ばまでは上昇傾向を示したが、(新型コロナウイルスの影響が大きかった2020-21 年 の期間を除けば)1970 年代半ば以降、低下傾向を示しており、今後、人口の高齢化に伴 ってさらなる低下を見せ、マイナスにまで落ち込む見通しであるということを示す。さ らに、日本の家計貯蓄率の最も重要な決定要因は人口の年齢構成であり、人口の年齢構 成によって日本の家計貯蓄率の水準も、過去および将来の動向もおおむね説明できると いうことを示す。
