宏观经济分析中的总供给曲线

The Aggregate Supply Curve in the Macroeconomic Analysis

总供给—总需求模型是宏观经济学的一种主要分析工具,然而,在多数教科书中,关于总供给曲线的论述或者不够全面,或者不够清晰,或者不够准确。为弥补这一不足,本文将全面而深入地讨论以下三个问题:总供给曲线的定义,总供给理论中的"长期"与"短期"含义,主要短期总供给曲线的推导;讨论的重点是准确理解这三个问题需要注意的关键点。

The AS-AD model is one of the main analytic tools in macroeconomics,in majority of textbooks,however,there exist some shortcomings in the expositions of aggregate supply curve such as incomplete or unclear or inaccurate description.In order to make up this deficiency,this paper overall and deeply discusses such three issues as the definition of aggregate supply curve,the meaning of ＂long-term＂ and ＂short-term＂ in aggregate supply theory as well as the derivation of main short-run AS curves.The focus of the discussion is on the key points for correctly understanding of these three issues.
