| 分别采用几何法和代数法，从需求一边研究影响LM曲线位置的因素和影响过程，分析了如何更为规范地表述LM曲线移动的问题，并结合我国实际分析了货币需求一边因素的变化对货币政策效果的影响。分析结果显示：影响LM曲线移动的因素有货币交易需求、货币投机需求和实际货币供给量的变动；货币交易需求函数和货币投机需求函数都有常数项；当LM曲线移动时，表述为LM曲线向上或下移动更为规范；货币交易需求和货币投机需求增加都会导致LM曲线向上移动；我国未来货币交易需求会减小而货币投机需求会增加，进而导致货币政策效应变小。 |

| Abstract: |
| When western macroeconomics textbooks at home and abroad introduce IS LM model, only the effect of real money supply change on LM curve is considered instead of the influence of the changes of money demand on the shift of LM curve.〖BP)〗Geometric and algebraic methods are used to analyze how to better normatively express LM curve shift and to analyze the impact of the change of money demand factors on monetary policy efficiency based on China’s reality and based on the factors and influential process affecting the shift of LM curve from demand side. Analysis results show that the factors affecting LM curve shift include money transaction demand, money speculation demand and the change of real money supply quantity, that both money transaction demand function and money speculation demand function have constant term, that when LM curve shifts, LM curve being described as upward or downward shift is more standard, that both money transaction demand and money speculation demand can cause LM curve to upward shift, and that in the future, China’s money transaction demand will decrease but money speculation demand will increase, which further give rise to the reducing of monetary policy effect. |
| Key words: LM curve shift real money supply quantity money transaction demand money speculation demand |
