近年来随着我国国债发行额和国债余额的急剧增长,国债负担率引起了人们的高度关注,但是从国际比较角度看,我国的国债负担率还较低,财政扩张空间较大。本文依据一定的理论基础和试验模型,就国债依存度对国债负担率的变化进行分析。 In recent years, with the rapid growth of the issuance of government bonds and the balance of national debts in China, the national debt burden rate has aroused people’s attention. However, from the perspective of international comparison, the debt burden of our country is still low, and there is ample room for fiscal expansion. Based on a certain theoretical basis and experimental model, this paper analyzes the changes of the national debt burden rate based on the dependence of national debt.
