Economic Complex Analysis for Approaching Economic Equilibrium and Economic Stability

Under the framework of complex economics, it is found that the Cauchy-Riemann equation and the Laplace equation construct the core of economic complex analysis, which describes economic equilibrium and economic stability. Combining fundamental solution of Cauchy-Riemann equation and Laplace equation, the stable economic functions are revealed, in which commodity function X and money function Y as complex economic function Z=X+iY link with price level P and output quantity Q. The numerical simulations provide visual results.
