ABSTRACT: First, the extensive quantum theory is researched. Second, Orrell‟s quantum economics is introduced. Third, we propose the extensive quantum economics and its three fundamental principles: duality, uncertainty principle and extensive statistics. Fourth, we may apply quantum principles, theory and mathematical equations to economics. The corresponding Schrödinger equation and its potentials are studies, in which different potentials correspond to different economic policies and development models in quantum economics, and form different results and varying energy levels. Fifth, we discuss some economic models, such as the nonlinear theory of economic growth and the multiply connected topological economics, etc. Finally, we propose a specific prediction method. Since quantum theory has rich mathematical and physical contents, so the extensive quantum economics not only may be applied to many economic regions, and theory may be corrected and developed.
KEY WORDS: economics, quantum, principle, theory, equation, model
