以2002年-2011年平稳性时间序列C差G和Y差G,即驻马店市城乡居民消费差距和收入差距的对数增长率为变量进行格兰杰因果关系分析和回归结构模型分析,结果显示驻马店市城乡居民收入差距在短期内对消费差距影响不显著,但较长期趋势表明,驻马店市城乡居民收入差距对消费差距还是有一定的影响,收入差距每增加一个百分点,消费差距会相应的增加0.77个百分点;驻马店市城乡居民消费差距对收入差距的影响在短期内影响较显著,同时驻马店市城乡居民消费差距每增加一个百分点,收入差距就会相应的增加近0.34个百分点,除了消费差距对收入差距的影响外,还有其他因素会对驻马店市城乡居民收入差距造成一定程度的影响。
Based on Granger causality analysis and regression structural model analysis, the author uses the logarithmic growth rate of C G and Y G, which is the stationary consumer time series between 2002 and 2011, as the consumer and urban residents in Zhumadian city. However, the longer-term trend shows that the income gap between urban and rural residents in Zhumadian City still has some impact on the consumer gap. With each one-percentage-point increase in the income gap, the consumer gap will increase correspondingly 0.77 percentage points; the impact of urban and rural residents in Zhumadian on the income gap in the short term impact more significant, while the urban and rural residents in Zhumadian every one percentage point increase in consumer income, the income gap will be a corresponding increase of nearly 0.34 percentage points, in addition to the consumer gap Income disparity, there are other factors that will affect the income gap between urban and rural residents in Zhumadian City to a certain extent.
