This paper proposes an original macroeconomic theory termed "Aggregate Economics," aimed at eliminating cyclical global economic crises at their root. The study contends that the essential triggers of contemporary crises lie in the excessive acceleration of financial currency, aggregate supply-demand imbalances, and systemic decision-making failures.Centered on the philosophical core of "Humanity as the Sovereign of Earth's Resources," this theory disrupts traditional factor allocation models and introduces a scientifically rigorous "25% Equalization Distribution Scheme." Under this framework, global resources and wealth are conditionally allocated in four equal 25% proportions to: Public Welfare, Scientific Research, Commercial Development, and Disaster Relief. By establishing globally unified rules for balanced development and mandating 100% enforcement, this framework seeks to achieve Pareto optimal resource allocation, thereby definitively ending global economic instability and ensuring the sustainable advancement of human civilization.
