马克思两大部类再生产理论的动态化和实证化研究

A Dynamic and Empirical Study on Marxist Reproduction Theory of Two-sector Economic Model

马克思的两大部类再生产理论存在着数理化、模型化、动态化和实证化的研究需要。本文通过将两大部类中的生产生产资料的第I部类进一步区分为生产原材料的部门和生产资本品的部门,尝试对两大部类再生产理论进行动态化建模,并将马克思两大部类的再生产理论与现代宏观经济学之间建立起联系。该模型不仅完全还原了马克思两大部类再生产过程必须满足的两大部类之间的交换条件,同时也推导出满足这一交换条件的两大部类之间的平衡增长路径,以及在平衡增长路径上所体现出的经济增长率。然而,我们同时也看到,在市场经济条件下,该平衡增长路径在现实中很难实现,由此论证了马克思所言的生产的社会化和生产资料的私有化之间的矛盾。最后的实证研究表明,马克思两大部类所必须保持的平衡增长路径能很好地解释中国过去的经济增长。

The reproduction theory of Marx's two-sector economic model still has the needs to be further studied from the aspects of mathematics,modeling,dynamics and empirical research.This paper will try to build a dynamic model of the reproduction theory of a twosector economy.By introducing important factors such as capital stock and investment that affect macroeconomic growth into the Marx's two-sector reproduction model,this study establishes a connection between Marx's two-sector reproduction theory and modern macroeconomics.The model not only completely restores the exchange conditions between the two sectors that must be met in the reproduction process,but also finds the balanced growth path and the growth rates at the balanced growth path.However,we also see that under the condition of market economy,such a balanced growth path is difficult to be achieved in reality,thus demonstrates the contradiction between the socialization of production and the privatization of means of production.Empirical research shows that the balanced growth path of Marx's two-sector economic model can well explains China's economic growth in the past.
