The impact of labor productivity and social production scale on aggregate demand and its deficiency: Functions and Analysis from the Perspective of Marx's Economic Theory in Das Kapital

This article, grounded in Marx's economic theory from Das Kapital, delves into the impact of labor productivity and social production scale on aggregate demand and its shortages, exploring the quantitative relationships and their underlying essence. It offers a theoretical framework for addressing macroeconomic issues such as insufficient aggregate demand, economic growth, and fluctuations. Initially, the article constructs and analyzes the functional relationship between aggregate social demand, labor productivity, and social production scale. Subsequently, it clarifies the concept of insufficient aggregate demand, establishes the functional relationship between this shortage and labor productivity as well as social production scale, and conducts an in-depth quantitative and institutional analysis of the issue. The article underscores that vigorously developing the socialist public ownership economy and adhering to and developing the socialist basic economic system constitute the fundamental institutional approach to resolving the shortage of aggregate demand.
