The invention discloses a method for solving a balanced solution of a scale population model based on density distribution reconstruction, and the method comprises the following steps: S1, building a population dynamics model with a scale structure according to the life cycle characteristics of a research object; s2, according to non-local boundary conditions, setting incubation growth amount and breeding circulation amount; s3, fixing the incubation growth amount, and solving the breeding circulation amount; s4, judging whether the population dynamics model is in a balance state or not according to the population number growth rate; if the state is the balance state, executing the step S5; if the state is the unbalanced state, the breeding circulation amount is used as the next incubation growth amount, and iteration is carried out until the breeding circulation amount is equal to the incubation growth amount; and S5, reconstructing population number distribution in an equilibrium solution state. According to the method, stable and unstable equilibrium solutions can be solved.

The application discloses a dynamic analysis method of a China energy economic society (CEES) CGE (Computable General Equilibrium) model, and belongs to the technical field of the computable general equilibrium model.The application realizes the method as follows: 1, obtaining energy economic society evaluation parameters corresponding to a domestic region in a preset period of a historical year; 2, constructing a CEES CGE comprehensive evaluation model for carbon neutralization policy distribution effect evaluation; 3, sequentially solving a commodity market equilibrium, a factor market equilibrium and a macro account balance through a multi-market recursive dynamic simultaneous solution algorithm, and solving the CEES CGE comprehensive evaluation model in different carbon neutralization policy scenarios in a recursive dynamic manner to obtain a general equilibrium solution, and obtaining an energy economic society evaluation index set corresponding to the domestic region in the preset period of the historical year.Compared with the prior art, the application solves the technical problems of the general equilibrium model, such as insufficient energy structure description, insufficient heterogeneity of the household department, limited social distribution effect recognition ability and insufficient long-term dynamic simulation ability.
