一个古典经济周期波动模型——对Goodwin古典周期模型的重构

基于古典主义思想对于劳动与资本这一经济运行核心关系的论述,本文对Goodwin周期模型进行了重构,构建一个由工资份额与资本存量组成的二维古典经济周期波动模型.稳定性分析结果表明,模型的均衡状态为非稳定焦点均衡,一旦脱离均衡点,经济将在工资份额与资本存量相互作用的驱动下围绕均衡点做周期性波动,且波动的幅度逐步加大.产生这一现象的根本原因在于工资性收入与资本性收入即资本存量之间比例结构的波动.

A Classical Economic Cycle Model-Reconstruction to Goodwin Cycle Model

Based on the classical viewpoint of labor and capital,this paper reconstructs Goodwin cycle model and constructs a classical economic cycle model on wage share and capital stock.The stability analysis shows that the equilibrium of model is non-equilibrium.Once out of equilibrium,the interaction between wage share and capital stock will bring about cyclical fluctuation.The essential reason of economic cycle is fluctuation of structural proportion of wage income and capital income.
