ABSTRACT: First, we research basic equations of the extensive quantum theory. Second, based on the extensive quantum economics, we propose wave-cycle and wave function. Third, we discuss the uncertainty of extensive quantum economics. Fourth, according to the extensive quantum statistics, the extensive quantum economics should be divided three types: BE economics, FD economics, mixed economics. Fifth, the input-output model corresponds to Heisenberg equation and S theory. Sixth, we search knowledge economics and its four theorems, and e-market. Seventh, we discuss some other mathematical methods in economics. Human society and economics are very complex, and the extensive quantum economics only provides a new research method and a possible development direction.
Key Words: economics, quantum, wave function, uncertainty, statistics, input-output model, knowledge, mathematics.
