A two-sector economy evolution model based on the general equilibrium and its simulation

A macro-economic system is divided into a new and developing sector and a traditional or developed sector in the paper, a nonlinear two-sector economic system evolution model is set up. Under general equilibrium, the evolution process of this economic system is discussed, and the solution is given. It is proven to be unstable by model analysis and simulation, and a bifurcation appears in the economic variable growth path. The mid-trajectory of this bifurcation is the turnpike of the nonlinear two-sector economic system evolution process.
