萨伊定律的争议及对我国宏观调控政策的启示

Controversies over Say’s Law and Its Implications for China’s Macro-control Policy

萨伊定律可概括为供给自动创造需求或生产会自行创造销路的理论,其提出以来饱受争议:一方面,马尔萨斯、西斯蒙第、凯恩斯、马克思等经济学家对其进行严厉批判;另一方面,新古典学派与供给学派对其进行继承与发展。本文对萨伊定律的争议及其历史地位演变历程进行阐述,并结合西方国家在宏观管理中的实践经验及我国国情,对我国宏观调控中采取的供给管理政策与需求管理政策进行深刻分析,提出我国经济发展应吸取萨伊定律中科学合理的部分,坚持供给侧结构性改革,以实现经济的长期稳定增长。

Say’s Law,which can be summarized as the theory that supply automatically creates demand or production creates sales by itself,has been controversial since its introduction.On the one hand,it has been severely criticized by economists like Malthus,Sismondi,Keynes,and Marx;on the other hand,it has been inherited and developed by neo-classical schools and supply schools.This paper elaborates on the controversies of Say’s Law and the evolutions of its historical status,combines the practical experience of Western countries in macro-management and China’s national conditions,deeply analyses supply management policies and demand management policies adopted in China’s macro-control,and puts forward that China’s economic development should draw on the scientific and reasonable parts of Say’s Law,and adhere to the supply-side structural reform to achieve the long-term and stable growth of the economy.
