消费、投资、出口占GDP比重变化对我国城乡居民收入及收入差距的影响

Impactof the Proportion Changes of Consumption,Investment,Exportsin GDP on China's Urban and Rural Households' Incomeand Income Gap

利用最新的统计数据,本文编制了2010年中国城乡居民收入分配投入占用产出表,通过构建投入产出最终需求结构变动模型,模拟分析了调整消费、资本形成和净出口占GDP比重变动对我国城乡居民收入增长及城乡居民收入差距的影响作用。研究结果表明,从增加总收入水平的角度看,扩大最终消费和净出口占GDP的比重对于我国居民总收入有正向拉动作用,而扩大资本形成占GDP的比重则会减少我国居民总收入。从缩小城乡居民收入差距的角度看,扩大消费起到了积极作用,而扩张投资和净出口则不利于我国城乡居民收入差距的缩小。

Using the latest statistics data,this paper compiles China's 2010 urban and rural income input-output table. By constructing input- output final demand structure change model,this paper analyzes the impact on China's urban and rural households' income and income gapwhen the proportion of consumption,investment,exports in GDP changed. The result shows that,from the point of increasing thetotal income,expanding final consumption and net exports share of GDP have a positive role in driving the income of urban and rural households and income gap,and expanding the proportion of investment in GDP plays a negative effect on China's households' income and income gap. From the angle of narrowing the income gap between urban and rural residents,expanding consumption takes a positive effect,while the expansion of investment and net exports are not conducive to shrink the income gap.
