Government debt 公债
（重定向自Public bond）
Government debt (also known as public debt, national debt and sovereign debt) is the debt owed by a central government. (In federal states, "government debt" may also refer to the debt of a state or provincial, municipal or local government.) By contrast, the annual "government deficit" refers to the difference between government receipts and spending in a single year, that is, the increase of debt over a particular year.
