货币流通速度变化的国际比较、收敛性及成因研究

The Changes of Money Velocity:International Comparison,Convergence and Reasons

本文基于全球各国的货币流通速度 （GDP/M2） 数据, 首先对比研究了全球货币流通速度走势, 发现全球不同收入层级国家的货币流通速度均具有下降趋势, 但是也存在明显差异.其次, 本文发现了不同收入层级国家货币流通速度具有明显的收敛特性, 并利用线性方程和多项式方程对收敛趋势进行了研究, 结果显示,全球货币流通速度大约在2030年左右大体会趋于-致, 数值大约为0.4947-0.776.最后, 本文对货币流通速度变化的原因进行了简单探讨.

Based on the data of the velocity of money(GDP/M2)around the world,this article does some re-searches on the trend of the velocity of money,and finds that money velocity of different income levels of countries isdecreased and exists some differences. Also the convergence of money velocity is found in this article,and the trend ofconvergence is studied with the linear equation and the polynomial equation. The results show that money velocity willbecome the same in about 2030 and the velocity of money is about the 0.4947 to 0.776. In the end,this article discuss-es the reasons of the change of money velocity.
