货币流动性过剩和城乡收入差距是困扰我国经济运行的两个主要问题。本文采用1991-2007年的数据,对货币流动性过剩和城乡收入差距之间的联系进行实证检验。结果表明,货币流动性过剩与城乡收入差距之间存在着长期的正相关关系,且互为因果关系,但城乡收入差距对货币流动性过剩的影响远大于货币流动性过剩对我国城乡收入差距的影响。因此,逐渐缩小城乡收入差距,扩大国内消费需求是解决货币流动性过剩问题的关键。 The excess liquidity in the currency and the income gap between urban and rural areas are two major problems plaguing the operation of our economy. This paper uses the data of 1991-2007 to test the relationship between excess liquidity and urban-rural income disparity. The results show that there is a long-term positive correlation between excess liquidity and income gap between urban and rural areas and mutual causation, but the effect of income gap between urban and rural areas on the excess of liquidity is much larger than that of excess liquidity on the income gap between urban and rural areas influences. Therefore, gradually narrowing the income gap between urban and rural areas and expanding domestic consumer demand are the keys to solving the problem of excess liquidity in the currency.
