The invention discloses an asymptotically stable attraction domain calculation method applied to a combined heat and power market. The calculation method comprises the following steps: establishing an energy supplier production strategy model, a terminal user optimal energy purchase model and a transaction center market clearing model based on a game theory; according to the constructed optimal strategy model, a dynamic market transaction mechanism is designed, and an optimal economic behavior model of each market subject is described based on a KKT condition and a gradient method; based on the established optimal economic behavior model, constructing a state-space equation of the combined heat and power market; and deducing an attraction domain calculation formula according to the Lyapunov stability theorem. According to the calculation method, the economic behavior is described based on the game theory, the economic behavior is converted into a space equation for describing the market operation state, then
