凯恩斯消费函数所揭示的消费、储蓄与可支配收入的关系在国民收入决定和总需求分析中有重要的应用。本文提出了以总收入为基础的含税消费函数,分析了其微观上的合理性,并从三个方面与凯恩斯消费函数进行了比较。实际数据的统计分析表明,至少从总量上看,人们的储蓄、消费决策更多地依赖总收入而不是可支配收入,税收、转移支付乘数数值上与政府支出乘数相等,平衡预算的财政政策不会对宏观经济具有扩张或紧缩的影响。
The relationship between consumption, saving and disposable income revealed by the Keynesian consumption function has important applications in national income decisions and aggregate demand analysis. This paper presents a tax-based consumption function based on total revenue, analyzes its microscopic rationality, and compares Keynesian consumption functions from three aspects. The statistical analysis of the actual data shows that at least in terms of total amount, people’s savings and consumption decisions depend more on total income than on disposable income. The tax and transfer payment multipliers are numerically equal to the government expenditure multiplier, Fiscal policy does not have the effect of macroeconomic expansion or contraction.
