The Effect of Labor Productivity and Social Production Scale on Profit-induced Demand Functions:Analysis from the Perspective of Marx's Economic Theory
Based on Marx's economic theory,this paper analyzes the effect,quantitative relationship and essence of labor productivity and social production scale on profit-induced demand.The scale of social production can be measured by the number of workers and the number of capital.This paper points out that when labor productivity increases and capital quantity expands,profit-induced demand does not necessarily increase.If the growth rate of organic composition of capital is higher than the growth rate of labor productivity and capital quantity,profit-induced demand will decline.This is the decline in aggregate demand or the intensification of aggregate demand shortage in economic growth.The instability of expectations and the time difference between investment in the formation of market supply and demand will lead to the inherent instability of demand caused by profits,which will lead to the inherent instability and periodicity of the macro economy.It is of great significance to pay special attention to these two points in macroeconomic policy formulation.On the basis of Marx's economic theory,the relationship between profit-induced demand function and its quantitative analysis are constructed,and the practical problems in macroeconomic operation are solved,which also proves the vitality of Marx's theory.
