消费行为理论是现代西方经济学中的一个重要领域,对宏观经济运行分析具有现实意义。宏观经济学视角下消费行为问题主要是对消费函数的研究。回顾绝对收入假说、相对收入假说、生命周期和永久性收入假说及现在方兴未艾的预防性储蓄假说、流动性约束假说、λ假说,消费理论的演变与整个西方主流宏观经济学发展潮流相吻合,深入探索消费函数理论的发展规律有益于宏观经济学的深入研究。 The theory of consumer behavior is an important field in modern western economics and has practical significance for the macroeconomic analysis. Consumer behavior under the macroeconomic perspective is mainly the study of the consumption function. Reviewing the absolute income hypothesis, the relative income hypothesis, the life-cycle and permanent income hypothesis and the now-defunct precautionary savings hypothesis, the liquidity constraint hypothesis, the λ hypothesis and the evolution of the consumption theory are consistent with the development trend of the mainstream western macroeconomics. Exploring the law of development of the consumption function theory is beneficial to the further study of macroeconomics.
