新供给经济学:宏观经济学的一个发展方向

New Supply-side Economics: A New Direction for Macroeconomics

当前宏观经济理论已经发展到总供求模型,但宏观调控理论依然建立在60年前形成的IS-LM模型的基础上,因此,宏观调控理论严重滞后于宏观经济学的发展。新供给经济学就是以总供求模型为基础建立起来的宏观调控理论,它在宏观调控中同时考虑并综合运用供给管理和需求管理。供给管理在短期和长期宏观调控中均可使用,供给管理的政策工具包括促进技术进步、制度创新、调节要素成本、调节税收、鼓励产品创新等。新供给经济学的理论源泉包括社会主义政治经济学、现代制度经济学以及供给学派。

Modern macroeconomics has developed to AD- AS model, while macroeconomic policy theory is still based on IS- LM model which was developed in 1950 s. Therefore the prevalent policy theory seriously lags behind the development in macroeconomic theory. New Supply-side Economics is macroeconomic policy theory based on AD-AS model, which employ both supply management and demand management in macroeconomic control. Supply management can be used in both short- and long- term managements. The sources of New Supply- side Economics are socialist political economy of China, modern institutional economics, and supply-side economics.
