摘　　要：在利润率分解式的基础上,基于工资对需求和成本的双重影响可以推导出工资—利润率倒U关系。将其引入后凯恩斯国民收入决定式中,结合利润率对资本积累的影响,以及资本积累通过劳动力需求对劳资分配的影响,可以构建出基于马克思理论逻辑的短期经济动态模型。在该模型中,消费不足经济危机、工资挤压利润经济危机和有机构成提高导致利润率下降危机,这三种经济危机类型的发生机制、条件和相互关系都能得到清晰的说明,有助于理解马克思危机理论之间的关系。在模型基础上,围绕经济政策与外生冲击对投资行为和利润率的影响,还可以为分析相关政策的作用提供不一样的视角。In the framework of the decomposition of profit rate,we can deduce the inverted U-shaped relationship between wage and profit rate based on wage’s dual impact on demand and cost.Then,based on the post-Keynesian national income determinant,combined with the impact of profit rate on capital accumulation and the impact of capital accumulation on labor demand and labor distribution,we can construct a short-term dynamic economic model rooted from Marx’s theory.In this model,the economic crisis of insufficient consumption,the economic crisis of wage squeezing profit and the crisis of declining profit rate caused by the increase of organic composition can all be clearly explained in terms of the mechanisms,conditions and their interrelationships,which is helpful to understanding Marx’s crisis theory.Based on this model,the effects of economic policies and exogenous shocks on investment behavior and profitability also provide new perspectives for analyzing relevant policies.
