摘要
本文基于哈罗德、多马和索洛关于经济增长理论的经典文献,对哈罗德-多马模型与索洛模型提供一个比较分析。本文的基本结论包括:1、并不像索罗模型宣称的那样,它接受除不变要素比例之外的所有哈罗德-多马假定,而是通过引入新古典生产理论,消除哈罗德-多马模型中的"黄金时代"问题;2、并不像索罗模型宣称的那样,它解决了哈罗德-多马模型中的"刃锋问题"(或称"不稳定性原理"),而是通过引入一种产品的总量生产函数和取消投资函数,从而取消了国民收入的会计恒等式和均衡条件式之间的区分,回避而不是解决了哈罗德-多马模型中的刃锋问题;3、资本-产出比也不像索洛模型宣称的那样,是生产函数的技术特征,而是关于价格机制的不同假定。
This article is an attempt to provide a comparative analysis of Harrod-Domar model and Solow growth model which is on the basis of the classical articles on economic growth theories written by Harrod, Domar and Solow. Three new viewpoints are included in this article： 1. Instead of accepting all the Harrod-Domar＇s assumptions except fixed ratio of factors as it claims, Solow model just eliminates the ＂golden-time＂ problem in Harrod-Domar model by introducing the Neoclassical production theory. 2. Rather than resolve the ＂blade problem＂ in Harrod-Domar model（also called instability principle） as is well-known, Solow model just succeeds in avoiding the ＂blade problem＂ by introducing the Gross Production Function and abolishing the Investment Function and eliminating the difference between the Accountant Identical Equation and Balance Conditional Equation of the national income. 3. The capital-output ratio in Solow model is not a technical nature as it claims, but a different assumption about the price mechanism. Additionally, the article also provides a comparative analysis between Keynesian theory and Harrod-Domar theory.
