近十几年来,我国经济发展迅速,每年GDP以较高比率增长,其中高储蓄高投资对经济增长的贡献巨大。然而,由于有效需求不足,储蓄在向投资转化的过程中受到阻塞,导致我国投资率长期低于储蓄率,引起我国宏观经济失衡,也造成我国储蓄资源极大的闲置。本文首先用索洛模型分析了高储蓄率对经济增长的贡献,然后建立对数线性模型进行了实证检验,最后探析了储蓄和投资的关系、转化机制及其中存在的种种障碍。
In the past decade or so, China’s economy has developed rapidly and its GDP has been growing at a relatively high rate each year. Among them, the high savings and high investment make a huge contribution to economic growth. However, due to the lack of effective demand, the savings have been blocked in the process of conversion to investment. As a result, the investment rate in our country has been below the saving rate for a long time, causing the imbalance in our country’s macroeconomy and causing great vacancy in China’s saving resources. Firstly, this paper analyzes the contribution of high savings rate to economic growth with Solow model, and then establishes a logarithmic linear model for empirical test. Finally, it analyzes the relationship between savings and investment, the transformation mechanism and the obstacles in it.
