据国际货币基金组织统计，如果要在2030年将净公共债务总额降低到相当于GDP80%的话，日本必须在2020年将当前8.6%的基本预算赤字转变为6.7%的基本盈余，并维持这一状况到2030年。
According to the IMF, to reduce its net public debt to 80% of GDP by 2030, Japan would have to turn today’s 8.6% primary budget deficit (the balance excluding interest payments) into a 6.7% primary surplus by 2020 and maintain such surpluses continuously until 2030.
