对凯恩斯消费函数的实证分析——以中国城市居民消费支出为例

英国经济学家凯恩斯以1929～1933年的经济大萧条为时代背景,在《通论》中提出了"消费函数"的概念。凯恩斯认为虽然有众多的因素都影响着居民的消费支出,但是具有决定意义的是居民收入水平。凯恩斯的消费函数理论自问世以来受到其他的消费理论的质疑,包括相对收入消费理论、生命周期消费理论和永久收入消费理论等。对于这些质疑,我们可以用实证的方法来验证凯恩斯消费函数。

British economist Keynes brought up the concept of eonsuption function in the book A General Treatise with the background of 1929-1933 economic depression. Keynes believed that income was the most important factor which affected consumption. There was many consumption theory schools, such as Relative Income Hypothesis of Consumption, Life Cycle Hypothesis of Consumption and Permanent Income Hypothesis of Consumption, which haboured suspicions after Keynes Consumption Function was presented to the public. Therefore it is necessary for us to test Keynes Consumption Function with the tool of positive economics.
