经济动态效率与我国最优消费率:1992～2013

The Dynamic Efficiency and the Optimal Consumption Rate of Economy in China: 1992～2013

将经济实现黄金律增长时对应的消费率界定为最优消费率,则经济动态效率为判断现实经济消费率与最优消费率之间的关系提供了一种思路：当经济处于动态无效状态时,现实经济的消费率低于最优消费率;当经济处于动态有效状态时,现实经济的消费率高于最优消费率。运用1992～2013年中国经济相关数据进行实证分析,结果显示：1992～2007年和2011～2012年中国经济动态有效,最终消费率高于最优消费率;2008～2010年和2013年经济呈动态无效,最终消费率低于最优消费率;1992～2013年期间中国的最优消费率大致为55%。最后给出了提高中国最终消费率的政策建议。

By defining the optimal consumption rate as when economy achieves the Golden Rule growth, the authors believe that dynamic efficiency of economy provides a way for judging the relationships between real economic consumption rate and the optimal consumption rate： when an economy is dynamically inefficient, ＇the consumption rate of real economy is lower than the optimal consumption rate ; when the economy is dynamically efficient, the consumption rate of real economy is higher than the optimal consumption rate. empirical study is made by using relative data of China＇ s economy from 1992 to 2013, and the results show that China＇ s economy is dynamically efficient from 1992 to 2007 and from 2011 to 2012, and the final consumption rate is higher than the optimal consumption rate; China＇ s economy is dynamically inefficient from 2008 to 2010 and in 2013, the final consumption rate is lower than the optimal consumption rate; China＇ s optimal consumption rate is around 55% during 1992 to 2013. Finally, policy recommendations on improving the final consumption rate of China are proposed.
