Dynamic Analysis of a Novel Four-Dimensional ESER System

This paper proposes a novel four-dimensional energy-saving and emission-reduction system (ES- ER). The system is established in accordance with the complicated relationship between energy-saving and emission-reduction, carbon emissions, economic growth and carbon tax. The dynamic behavior of the sys- tem is analyzed by means of Lyapunov exponents and bifurcation diagrams. The periodic orbits are explored, and the ESER attractor with carbon tax constraints is put forward. Numerical simulations are presented to demonstrate the results.
