本文从两个角度对真实储蓄率进行了改进:一是将政府经常性支出作为制度因素纳入真实储蓄核算,解决了真实储蓄率与新国民财富体系在统计口径上的不一致问题;二是将外贸因素纳入真实储蓄核算,从对外开放风险的角度克服真实储蓄率在资源经济价值核算上的缺陷。本文的实证研究证明了制度因素纳入真实储蓄率的合理性和对外开放程度会影响资金使用效率,但是对外贸风险的线性调整方式在统计意义上并不显著。
We improve the genuine savings rate from two aspects. First, we add government recurrent expenditure in genuine savings rate, from which we solve the inconsistency of genuine savings and new national wealth accounting. Second, we adjust the genuine savings rate by import and export, which can consider the opening risk of a nation. Adding government recurrent expenditure as institutional capital in genuine savings rate is proved reasonable in the empirical research, and import and export shows its importance in capital efficieney of genuine savings, but adding it to genuine saving rates linearly is not supported in the empirical research.
